Strong Stellar Winds

Science, 1980
The hottest and most luminous stars lose a substantial fraction of their mass in strong stellar winds. These winds not only affect the evolution of the star, they also carve huge expanding cavities in the surrounding interstellar medium, possibly affecting star formation. The winds are probably driven by radiation pressure, but uncertainties persist in

Stellar wind theories

Astrophysics and Space Science, 1997
The author surveys the basic theory of stellar winds with momentum input due to a force or with energy input. Five laws of stellar winds are formulated, and different wind mechanisms, line-driven model and dust-driven models are discussed.

Binary stellar winds

Astrophysics and Space Science, 1974
Stellar winds from a binary star pair will interact with each other along a contact discontinuity. We discuss qualitatively the geometry of the flow and field resulting from this interaction in the simplest case where the stars and winds are identical.

Numerical Simulations of Stellar Winds

Space Science Reviews, 1999
We discuss steady-state transonic outflows obtained by direct numerical solution of the hydrodynamic and magnetohydrodynamic equations. We make use of the Versatile Advection Code, a software package for solving systems of (hyperbolic) partial differential equations.

Stellar wind theory

Journal of Geophysical Research: Space Physics, 1980
The theory of stellar winds as given by the equations of classical fluid dynamics is considered. The equations of momentum and energy describing a steady, spherically symmetric, heat‐conducting, viscous stellar wind are cast in a dimensionless form which involves a thermal conduction parameter E and a viscosity parameter γ.

Stellar rotation effects on the stellar winds

Physics of Plasmas, 2020
The purpose of this paper is to give detailed systematic considerations to clarify and provide insights and a qualitative guide into the role of the azimuthal wind flow in the stellar-rotation braking mechanism. For this purpose, we make use of the Weber-Davis [Astrophys. J. 148, 217 (1967)] magnetohydrodynamic (MHD) version of Parker's [Astrophys.
