Grids of stellar models with rotation - I. Models from 0.8 to 120 M⊙ at solar metallicity (Z = 0.014)
Sylvia Ekström,Cyril Georgy,Patrick Eggenberger,Georges Meynet,Nami Mowlavi,Aurélien Wyttenbach,Anahí Granada,Anahí Granada,Thibaut Decressin,Raphael Hirschi,Raphael Hirschi,Urs Frischknecht,Urs Frischknecht,Corinne Charbonnel,Corinne Charbonnel,André Maeder +15 more
TL;DR: In this paper, a set of models for solar metallicity, where the effects of rotation are accounted for in a homogeneous way, is presented, and a grid of 48 different stellar evolutionary tracks, both rotating and non-rotating, at Z ǫ = 0.014, spanning a wide mass range from 0.8 to 120 m ⊙.

TL;DR: In this paper, a set of models for solar metallicity, where the effects of rotation are accounted for in a homogeneous way, is presented, and a grid of 48 different stellar evolutionary tracks, both rotating and non-rotating, at Z=0.014 are computed.
Journal ArticleDOI
Fast core rotation in red-giant stars as revealed by gravity-dominated mixed modes
Paul G. Beck,Josefina Montalbán,Thomas Kallinger,Joris De Ridder,Conny Aerts,Rafael A. García,Saskia Hekker,Marc-Antoine Dupret,Benoit Mosser,Patrick Eggenberger,Dennis Stello,Yvonne Elsworth,S. Frandsen,Fabien Carrier,Michel Hillen,M. Gruberbauer,Joergen Christensen-Dalsgaard,Andrea Miglio,Marica Valentini,Timothy R. Bedding,Hans Kjeldsen,Forrest R. Girouard,Jennifer R. Hall,Khadeejah A. Ibrahim +23 more
TL;DR: An increasing rotation rate from the surface of the star to the stellar core in the interiors of red giants is reported using the rotational frequency splitting of recently detected ‘mixed modes’, which confirms the theoretical prediction of a steep gradient in the rotation profile towards the deep stellar interior.
Journal ArticleDOI

TL;DR: In this article, the rotational splittings and frequencies of the modes for six young Kepler red giants were extracted and a seismic modeling of these stars using the evolutionary codes Cesam2k and astec was performed.
Journal ArticleDOI
The Geneva stellar evolution code
Patrick Eggenberger,Georges Meynet,André Maeder,Raphael Hirschi,Corinne Charbonnel,Corinne Charbonnel,Suzanne Talon,Sylvia Ekström +7 more
TL;DR: In this paper, the Geneva stellar evolution code with special emphasis on the modeling of solar-type stars is presented. And the basic input physics used in the Geneva code as well as the modelling of atomic diffusion is first discussed.
