Impact of magnetic activity on inferred stellar properties of main sequence Sun-like stars

no code implementations4 Feb 2021 Alexandra E. L. Thomas, William J. Chaplin, Sarbani Basu, Ben Rendle, Guy Davies, Andrea Miglio

We also warn that for stars with very high or low inclination angles, the response of modes to activity is more easily observable in the separation ratios and hence will incur a larger bias.

Solar and Stellar Astrophysics

New axion and hidden photon constraints from a solar data global fit

no code implementations7 Jan 2015 Núria Vinyoles, Aldo Serenelli, Francesco L. Villante, Sarbani Basu, Javier Redondo, Jordi Isern

We present a new statistical analysis that combines helioseismology (sound speed, surface helium and convective radius) and solar neutrino observations (the $^8$B and $^7$Be fluxes) to place upper limits to the properties of non standard weakly interacting particles.

Solar and Stellar Astrophysics

New solar opacities, abundances, helioseismology, and neutrino fluxes

1 code implementation16 Dec 2004 John N. Bahcall, Aldo M. Serenelli, Sarbani Basu

We construct solar models with the newly calculated radiative opacities from the Opacity Project (OP) and recently determined (lower) heavy element abundances.

Solar Models: current epoch and time dependences, neutrinos, and helioseismological properties

no code implementations17 Oct 2000 John N. Bahcall, M. H. Pinsonneault, Sarbani Basu

We calculate accurate solar models and report the detailed time dependences of important solar quantities.

How Uncertain Are Solar Neutrino Predictions?

no code implementations12 May 1998 John N. Bahcall, Sarbani Basu, M. H. Pinsonneault

Solar neutrino fluxes and sound speeds are calculated using a systematic reevaluation of nuclear fusion rates.
