Author name code: evershed ADS astronomy entries on 2022-09-14 author:"Evershed, John" ------------------------------------------------------------------------ Title: Recollections of seventy years of scientific work Authors: Evershed, J. Bibcode: 1955VA......1...33E Altcode: This article records some of the researches in solar physics undertaken during my life. These have included the following: prominence observations covering sixteen years; spectroheliograph work with a direct vision prism; experiments on the radiation of heated gases; eclipse expeditions in 1898 and 1900; studies of the relation between emission and absorption spectra, and of the continuous spectrum of hydrogen. In India (1906-1923) my work included: the discovery of radial motion and the estimate of pressure in sunspots; a study of the exceptional observing conditions in Kashmir; measurements of the red-shift in connection with EINSTEIN'S prediction; great magnetic storms during flares; the motion in the tail of HALLEY'S comet and its transit over the Sun; observations of novae. At Ewhurst (1923-1954) I was concerned with: high-dispersion work with liquid prisms; the study of the Zeeman effect and the discovery of a particularly sensitive line for its determination; measurements of minute line-shifts due to horizontal motions; and the decrease of wavelength of solar lines. Reference is made to scientific men I have met and to whom I am indebted for interest and encouragement. Title: Report of his observatory (Ewhurst) Authors: Evershed, J.

Bibcode: 1923Natur.112R.901E Altcode: THE type of cloud photographed by Dr. Lockyer (NATURE, November 17, p. 725) is very frequently seen at Kodaikanal in south India during the thunderstorm season in April and May. It is always associated with thunder and always appears after the thunder clouds have expended their electrical energy. This often happens quite suddenly when the storm is of local origin.

Bibcode: 1923Natur.111...13E Altcode: SIR ARTHUR SCHUSTER in his review of Dr. Mulder's book on this subject states that ``there seems no reason to doubt that dispersion combined with absorption of light completely accounts for the effect'' (NATURE, September 16, p. 370). Yet Dr. Mulder's own view is that a complete explanation is still wanting. Title: The spectrum of Sirius Authors: Evershed, J.

Bibcode: 1921Natur.108..566E Altcode: REFERRING to Father Cortie's letter on this subject (NATURE, October 27, p. 272), the sequence of magnetic disturbances following at 27-day intervals the storms of May 12-21, 1921, was recorded also at Kodaikanal, but those storms recorded in England as ``very great'' on September 2 and 28-29 were classed here as ``moderate '' only. There were also recorded here ``great'' storms on March 21-22 and April 18-19, which appear to belong to the same sequence, the whole interval from March 22 to September 29 giving a mean period of 27.29 days. Assuming this to be the synodical period of the sun, the equivalent sidereal period is 25.42 days, closely agreeing with Carrington's mean value of the rotation for spots.

Bibcode: 1918Natur.102..105E Altcode: IN NATURE of June 13 I note that the earliest observation of Nova Aquilæ in England was made by Miss Grace Cook at 9.30 G.M.T. on June 8, and the magnitude was estimated as equal to Altair. In India the star was seen and recognised as a nova about five hours earlier by Mr. G. N. Bower in Madras, who has sent me his original notes made at 10 p.m. Indian Standard Time on June 8 (corresponding with 4.30 p.m. G.M.T.). Mr. Bower was occupied in pointing out the principal stars and constellations to a friend, and identifying them with the aid of Mrs. Evershed's ``Guide to the Southern Stars.'' Turning to the eastern sky, he at once saw a star on the borders of Aquila and Serpens which he could not place. It appeared to be as bright as Altair, or possibly brighter, but not so bright or white as Vega. Altair was, however, unfavourably placed for the comparison.

Bibcode: 1916Obs....39...59E Altcode: No abstract at ADS Title: A Question of Albedo Authors: Evershed, J. Bibcode: 1915Natur..96..369E Altcode: THE past summer in the Kashmir Valley has been one of extraordinary dryness, with continuous blue skies and hot sunshine. These conditions have extended into the autumn, and during the month of October even the surrounding mountains, so often clouded, have been entirely clear. The snow-line, instead of descending to lower elevations with the advance of the season, has steadily risen, until at the date of writing only a few isolated patches of white can be seen on the Pir Panjal range on the south-west side of the valley, and no snow at all on the mountains towards the east. It was with a distinct shock of surprise, therefore, that at sunset on the date October 22 we noticed a beautiful dome of snow just topping the eastern mountains, which were still brilliantly illuminated by the sun. For a few moments the only possible explanation seemed to be that one of the higher peaks of the central Himalayan ranges had made a prodigious upward thrust of several thousands of feet! However, the earth's rotation movement rapidly transformed this snowfield into the familiar features of the full moon. Title: Note on the Atmospheric Conditions Required for Astronomical Observations Authors: Evershed, John Bibcode: 1915PASP...27..179E Altcode: No abstract at ADS Title: The Green Flash Authors: Evershed, John Bibcode: 1915Natur..95..286E Altcode: MANY descriptions of the green flash have been published in letters to NATURE and elsewhere, but I do not remember to have seen a satisfactory explanation of this curious phenomenon. Atmospheric dispersion is invoked, but this does not explain the absence of the red end of the spectrum. My observations agree in every particular with those described by Mr. Whitmell in NATURE of March 11, p. 35. At sea I have observed a violet or blue tint occasionally, and on one occasion a red flash as the lower limb of the sun emerged from a cloud into a clear space very near the horizon.

Bibcode: 1911Natur..87..111E Altcode: IF it is true, as Mr. Buss suggests, that variations in the intensity of the components of the emission line K2 on either side of the absorption line K3 are sufficient to account for the dark markings occasionally found in spectroheliograms, then the Kodaikánal plates should show them as conspicuously as those taken with a high dispersion instrument, which isolates the central line. Yet this, as Mr. Buss has himself pointed out, is not the case. In studying high dispersion spectrum photographs of the solar disc, one occasionally discovers places where the K3 line is abnormally dark, and the same thing may also be well observed in the line Hα. When the spectroscope slit chances to cross one of these linear markings, an intensely black spot is seen on the absorption line, and this will usually remain visible or run along the line if the solar image is moved slightly. In the case of the lines H and K, the components of the emission lines H2 and K2 are, I think, always weak at the points of greatest darkness in the absorption lines, and for this reason they may possibly contribute somewhat to the final result in our plates.

Bibcode: 1898Obs....21..404E Altcode: No abstract at ADS Title: Solar Radiation Authors: Evershed, J. Bibcode: 1898Natur..58..619E Altcode: AT the conclusion of his British Association lecture on Phosphorescence1, Mr. Jackson makes a suggestion with regard to solar radiation which will doubtless receive due attention from those who are interested in solar physics. It is one of especial interest to me because, by an entirely different train of thought, Mr. Jackson has arrived at a possible explanation of the relation between sun-spots and terrestrial magnetic disturbances which is practically identical with a suggestion I have recently put forward in a paper on ``The cause of the darkness of sunspots,'' published in the Astrophysical Journal (April 1897). Title: 1898 January 22, note on some results obtained with a small prismatic camera at the Eclipse Camp at Talni Authors: Evershed, J.

Bibcode: 1898MmBAA...6...12E Altcode: No abstract at ADS Title: The Corona Spectrum Authors: Evershed, J. Bibcode: 1897Natur..56..444E Altcode: IN your article on the approaching solar eclipse (page 393, paragraph 2), reference is made to the apparent absence of the corona line, 1474 K, from the chromosphere and prominences. I would like to point out that occasionally this line is clearly seen reversed in metallic prominences; and that the form of the prominence, generally a very small one, can be made out with the widened slit as in the other chromosphere lines. Such an instance is recorded by Fenyi, who has published a drawing of the prominence as seen in the lines 6677, C, and 1474 K; the height as measured in the last-named line being 33'' (``Astronomy and Astro-physics,'' xi. 432, 1892).

Bibcode: 1895Natur..52..508E Altcode: THE forms of birds flying at a great height and crossing the solar disc, as described by Mr. Bray in your issue of August 29, have been rather frequently seen here during the spring and autumn months, and the writer has always attributed such flights to migrating birds on passage. They have usually been noticed while observing the image of the sun projected on a card screen from the eyepiece of a small equatorial telescope; occasionally, however, they have attracted attention at night also, crossing the disc of the moon, upon which their forms are very clearly defined, and with careful focussing (which is very nearly the same as for parallel rays) it has almost been possible to identify the species from the shape of the wings and manner of flight; birds of the swallow tribe, in particular, have been clearly distinguished, and others resembling the thrush, possibly redwings or fieldfares, have been noticed. The direction of flight, according to the writer's experience, is nearly always towards the south in August and September, and the reverse in April. Title: The Corona Spectrum Authors: Evershed, J. Bibcode: 1893Natur..48..268E Altcode: IN the preliminary account by M. Deslandres of the main results of the eclipse, photographs obtained by the French astronomers at Fundium, as reported in this journal on May 25 (vol. xlviii. p. 81), it is stated that many new coronal lines have been photographed, and that a displacement of the lines in the light from opposite points of the corona in the solar equatorial plane proves a rotational movement nearly corresponding with that of the surface of the sun itself. Title: The Chromosphere Authors: Evershed, John Bibcode: 1887Natur..37...79E Altcode: HAVING lately devised a spectroscope with two small sextant telescopes and two small prisms, one of ``extra dense'' glass by Hilger, I attached it to a 2½-inch telescope, and tried its powers on the sun on the 6th inst., with the result that not only were the rays C and D3 easily visible as bright lines, but I also found that by opening the slit and keeping the brighter part of the spectrum out of view I could see the actual ragged surface of the ``storm-tossed sea of hydrogen.''
