Does solar structure vary with solar magnetic activity?
Sarbani Basu, Anna Mandel
We present evidence that solar structure changes with changes in solar activity. We find that the adiabatic index, Gamma_1, changes near the second helium ionization, i.e., at a de…

Constraining solar abundances using helioseismology
Sarbani Basu, H. M. Antia
Recent analyses of solar photospheric abundances suggest that the oxygen abundance in the solar atmosphere needs to be revised downwards. In this study we investigate the consequen…

Asteroseismic determination of helium abundance in stellar envelopes
Sarbani Basu, Anwesh Mazumdar, H. M Antia +1
Intermediate degree modes of the solar oscillations have previously been used to determine the solar helium abundance to a high degree of precision. However, we cannot expect to ob…
