Journal ArticleDOI
Accretion-powered Stellar Winds as a Solution to the Stellar Angular Momentum Problem
TL;DR: In this article, the angular momentum extracted by a wind from a pre-main-sequence star to the torques arising from the interaction between the star and its Keplerian accretion disk is compared.
Journal ArticleDOI
The mass-dependence of angular momentum evolution in sun-like stars
Sean P. Matt,A. Sacha Brun,Isabelle Baraffe,Isabelle Baraffe,Jerome Bouvier,Jerome Bouvier,Gilles Chabrier,Gilles Chabrier +7 more
TL;DR: In this article, a physically motivated scaling for the dependence of the stellar wind torque on the Rossby number was derived, which explains why the lowest mass stars are observed to maintain rapid rotation for much longer than solar-mass stars.
Journal ArticleDOI
The Effect of Magnetic Topology on Thermally Driven Wind: Toward a General Formulation of the Braking Law
Victor Réville,Allan Sacha Brun,Sean P. Matt,Antoine Strugarek,Antoine Strugarek,Rui F. Pinto,Rui F. Pinto +6 more
TL;DR: In this paper, the authors considered a dipolar stellar magnetic field, both quadrupolar and octupolar configurations, while also varying the rotation rate and the magnetic field strength, and gave a unique law that fits the data for every topology by formulating the torque in terms of the amount of open magnetic flux in the wind.
Journal ArticleDOI
Magnetic braking formulation for sun-like stars: dependence on dipole field strength and rotation rate
TL;DR: In this article, the authors used two-dimensional axisymmetric magnetohydrodynamic simulations to compute steady-state solutions for solar-like stellar winds from rotating stars with dipolar magnetic fields.
Journal ArticleDOI
Accretion-powered Stellar Winds. II. Numerical Solutions for Stellar Wind Torques
Sean P. Matt,Ralph E. Pudritz +1 more
TL;DR: In this paper, the role of stellar winds in torquing down the stars was explored, and the stellar winds need to have relatively high outflow rates, and thus would likely be powered by the accretion process itself.
