Astrospheres and Solar-like Stellar Winds [PDF]

open access: yesLiving Reviews in Solar Physics, 2004
Stellar analogs for the solar wind have proven to be frustratingly difficult to detect directly. However, these stellar winds can be studied indirectly by observing the interaction regions carved out by the collisions between these winds and the ...

Stellar winds from Massive Stars [PDF]

open access: yes, 2000
We review the various techniques through which wind properties of massive stars - O stars, AB supergiants, Luminous Blue Variables (LBVs), Wolf-Rayet (WR) stars and cool supergiants - are derived. The wind momentum-luminosity relation (e.g.

Nonthermal Motions and Atmospheric Heating of Cool Stars

open access: yesThe Astrophysical Journal, 2023
The magnetic processes associated with the nonthermal broadening of optically thin emission lines appear to carry enough energy to heat the corona and accelerate the solar wind.

Comparison of theoretical radiation-driven winds from stars and discs [PDF]

open access: yes, 1999
We compare models of line-driven winds from accretion discs and single spherical stars. We look at the problem of scaling mass-loss rates and velocities of stellar and disc winds with model parameters.

Stellar feedback efficiencies: supernovae versus stellar winds [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
Stellar winds and supernova (SN) explosions of massive stars ('stellar feedback') create bubbles in the interstellar medium (ISM) and insert newly produced heavy elements and kinetic energy into their surroundings, possibly driving turbulence. Most of this energy is thermalized and immediately removed from the ISM by radiative cooling.

Accretion‐powered Stellar Winds. II. Numerical Solutions for Stellar Wind Torques [PDF]

open access: yesThe Astrophysical Journal, 2008
[Abridged] In order to explain the slow rotation observed in a large fraction of accreting pre-main-sequence stars (CTTSs), we explore the role of stellar winds in torquing down the stars. For this mechanism to be effective, the stellar winds need to have relatively high outflow rates, and thus would likely be powered by the accretion process itself ...

A Review of the Theory of Galactic Winds Driven by Stellar Feedback

open access: yesGalaxies, 2018
Galactic winds from star-forming galaxies are crucial to the process of galaxy formation and evolution, regulating star formation, shaping the stellar mass function and the mass-metallicity relation, and enriching the intergalactic medium with metals ...

Dust Coagulation in Oxygen-rich Circumstellar Outflows

open access: yesThe Astrophysical Journal, 2023
We show that the inefficient growth of SiO molecules on (SiO) _x dust grains prolongs the period of maximum dust nucleation in circumstellar outflows resulting in a several orders-of-magnitude increase in the dust density near the star.

Braking down an accreting protostar: disc-locking, disc winds, stellar winds, X-winds and Magnetospheric Ejecta [PDF]

open access: yes, 2013
Classical T Tauri stars are low mass young forming stars that are surrounded by a circumstellar accretion disc from which they gain mass. Despite this accretion and their own contraction that should both lead to their spin up, these stars seem to ...

A Disk Wind Driving the Rotating Molecular Outflow in CB 26

open access: yesThe Astrophysical Journal, 2023
We present the ^12 CO ( J = 2–1) sensitive molecular line and 1.3 mm continuum observations from the Submillimeter Array (SMA) of the bipolar outflow associated with the young star located in the Bok globule known as CB 26.
