Astrospheres and Solar-like Stellar Winds [PDF]
Living 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 ...

Molecules in Stellar Winds [PDF]
Symposium - International Astronomical Union, 1992 High mass-loss molecular winds are characterstic of two important phases of stellar evolution, very young protostars and stars on the asymptotic branch. Novel chemical processes in these winds suggest a variety of new astronomical observations.

Nonthermal Motions and Atmospheric Heating of Cool Stars
The 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.

Dust Coagulation in Oxygen-rich Circumstellar Outflows
The 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.

A Disk Wind Driving the Rotating Molecular Outflow in CB 26
The 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.

AGB Winds with Gas-Dust Drift in Stellar Evolution Codes
Universe, 2021 A significant fraction of new metals produced in stars enter the interstellar medium in the form of dust grains. Including dust and wind formation in stellar evolution models of late-stage low- and intermediate-mass stars provides a way to quantify their

Stellar feedback efficiencies: supernovae versus stellar winds [PDF]
Monthly 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]
The 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
Galaxies, 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 ...

Constraints on Magnetic Braking from the G8 Dwarf Stars 61 UMa and τ Cet
The Astrophysical Journal Letters, 2023 During the first half of their main-sequence lifetimes, stars rapidly lose angular momentum to their magnetized winds, a process known as magnetic braking.
