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.

Stellar winds in a-type supergiants [PDF]
International Astronomical Union Colloquium, 1989 The contribution of A supergiant stars to the return of mass and energy to the interstellar medium is not very important. Abbott (1982) analised a sample of early stars and concluded that B and A supergiants provided less than 8 % of the mass input to the ISM by stellar winds.

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.

X-ray Shaping of Planetary Nebulae
Galaxies, 2018 The stellar winds of the central stars of planetary nebulae play an essential role in the shaping of planetary nebulae. In the interacting stellar winds model, the fast stellar wind injects energy and momentum, which are transferred to the nebular ...

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 ...

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.

Magnetospheric outflows in young stellar objects
EPJ Web of Conferences, 2014 Different classes of outflows are associated with the magnetospheric activity of accreting T Tauri protostars. Stellar winds are accelerated along the open field lines anchored in the stellar surface; disk winds (extended or X-type) can be launched along

Radiatively-driven stellar winds [PDF]
International Astronomical Union Colloquium, 1986 In this review, attention will be focussed exclusively on the winds of hot stars, concentrating for the most part on spectral types 0 and B. For these stars, a clear consensus has emerged that it is the gradient of selective radiation pressure - i.e., line-driving - that explains the high terminal velocities, typically ~ 2000 km s−1, of their winds ...

A Study of Primordial Very Massive Star Evolution
The Astrophysical Journal, 2023 We present new evolutionary models of primordial very massive stars with initial masses ranging from 100 to 1000 M _⊙ that extend from the main sequence to the onset of dynamical instability caused by the creation of electron–positron pairs during core C,

An Ultraviolet View of Stellar Winds [PDF]
Symposium - International Astronomical Union, 1979 Ultraviolet observations of mass-loss effects in O stars have, over the past decade, revealed a broad picture of a phenomenon whose extent was only partially evident from earlier ground-based observations. Ultraviolet resonance lines of a variety of ionization stages of several common elements provide a comprehensive probe of the low-density, extended ...
