Asteroseismic modelling of solar-type stars: A deeper look at the treatment of initial helium abundance

no code implementations15 Oct 2020 Benard Nsamba, Nuno Moedas, Tiago L. Campante, Margarida S. Cunha, Antonio García Hernández, Juan C. Suárez, Mário J. P. F. G. Monteiro, João Fernandes, Chen Jiang, Babatunde Akinsanmi

Adopting 35 low-mass, solar-type stars with multi-year Kepler photometry from the asteroseismic "LEGACY" sample, we explore the systematic uncertainties on the inferred stellar parameters (i. e., radius, mass, and age) arising from the treatment of the initial helium abundance in stellar model grids .

Predicted Yield of Transits of Known Radial Velocity Exoplanets from the TESS Primary and Extended Missions

1 code implementation15 Nov 2018 Paul A. Dalba, Stephen R. Kane, Thomas Barclay, Jacob L. Bean, Tiago L. Campante, Joshua Pepper, Darin Ragozzine, Margaret C. Turnbull

From these probabilities, we predict that $25. 5^{+0. 7}_{-0. 7}$ of the known RV exoplanets should transit their host stars.
