Title: Sensitivity of Solar Eigenfrequencies to the Age of the Sun
Authors: Gough, D. O.; Novotny, E.
Bibcode: 1990SoPh..128..143G
Altcode: 1990IAUCo.121P.143G
The increasing central concentration of the Sun with age modifies
the acoustic eigenfrequencies. In particular, the frequency separation
dl=3(2l+3)−1«vn,l−vn−1,l+2»
for modes with l + 1/2 ≪ n decreases as nuclear reactions augment
the molecular-weight gradient in the energy-generating core. If,
for example, the Sun were older than is generally believed, one
might therefore expect dl to be smaller than current
theoretical predictions. On the other hand, to ensure that the
luminosity is consistent with observations, the presumed initial
hydrogen abundance would need to be enhanced, thereby reducing the
resultant molecular-weight gradient. Thus there is some degree of
cancellation of the two major factors that determine dl.

Title: The Effects of Recent Opacity Corrections on a Main-Sequence
Stellar Model of 2.25 M_{sun}
Authors: Novotny, Eva
Bibcode: 1972ApJ...174..425N
Altcode:
A comparison is made between models calculated with the opacities of
Carson, Mayers, and Stibbs and the electron-scattering corrections
of Watson with models based on the opacities of Cox, Stewart, and
Eilers. The models have a mass of 2.25 M0 and a chemical composition
with X = 0.596 and Z = 0.02 With the adopted formulae representing the
new opacities, it is found that the percentage changes with respect
to the model based on the opacities of Cox et at. can be as large
as + 11 for the stellar radius, -42 for the luminosity, - 15 for the
effective temperature, - 30 for the mass of the convective core, -8
for the central pressure, and -4 for both the central density and the
central temperature.
