Modules for experiments in stellar astrophysics (mesa): binaries, pulsations, and explosions
Bill Paxton,Pablo Marchant,Josiah Schwab,Evan B. Bauer,Lars Bildsten,Lars Bildsten,Matteo Cantiello,Luc Dessart,Robert Farmer,Haili Hu,Norbert Langer,Richard H. D. Townsend,Dean M. Townsley,Francis Timmes +13 more
TL;DR: Modules for Experiments in Stellar Astrophysics (MESA) as discussed by the authors can now simultaneously evolve an interacting pair of differentially rotating stars undergoing transfer and loss of mass and angular momentum, greatly enhancing the prior ability to model binary evolution.
Journal ArticleDOI
Evolution of binary stars and the effect of tides on binary populations
TL;DR: In this paper, a rapid binary-evolution algorithm was proposed to model the formation and evolution of binary systems, including all aspects of single-star evolution, features such as mass transfer, mass accretion, common envelope evolution, collisions, supernova kicks and angular momentum loss mechanisms.

Improved Age Estimation for Solar-Type Dwarfs Using Activity-Rotation Diagnostics
TL;DR: In this article, the authors derived an improved activity-age calibration for F7-K2 dwarfs (0:5 mag < B -V < 0.9 mag).

Orbital migration of the planetary companion of 51 Pegasi to its present location
TL;DR: In this paper, the authors show that if the companion is indeed a gas-giant planet, it is extremely unlikely to have formed at its present location, and suggest instead that the planet probably formed by gradual accretion of solids and capture of gas at a much larger distance from the star (∼5 AU), and that it subsequently migrated inwards through interactions with the remnants of the circumstellar disk.
