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 ...

(Sub)stellar companions shape the winds of evolved stars [PDF]

open access: yesScience, 2020
Complex stellar winds from evolved stars Stars less than eight times the mass of the Sun end their lives as planetary nebulae, structures of ionized gas thrown off by the star and heated by the exposed stellar core. Planetary nebulae are often bipolar in

A Review of the Theory of Galactic Winds Driven by Stellar Feedback [PDF]

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 ...

Ab Initio Horizon-scale Simulations of Magnetically Arrested Accretion in Sagittarius A* Fed by Stellar Winds [PDF]

open access: bronzeAstrophysical Journal, 2020
We present 3D general relativistic magnetohydrodynamic (GRMHD) simulations of the accretion flow surrounding Sagittarius A* that are initialized using larger-scale MHD simulations of the ∼30 Wolf–Rayet (WR) stellar winds in the Galactic center.

Gusty, gaseous flows of FIRE: galactic winds in cosmological simulations with explicit stellar feedback [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
We present an analysis of the galaxy-scale gaseous outflows from the Feedback in Realistic Environments (FIRE) simulations. This suite of hydrodynamic cosmological zoom simulations resolves formation of star-forming giant molecular clouds to z = 0, and ...

On the deceleration of Fanaroff–Riley Class I jets: mass loading by stellar winds [PDF]

open access: bronze, 2014
Jets in low-luminosity radio galaxies are known to decelerate from relativistic speeds on parsec scales to mildly or sub-relativistic speeds on kiloparsec scales.

Stellar winds and photoionization in a spiral arm [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
The role of different stellar feedback mechanisms in giant molecular clouds is not well understood. This is especially true for regions with many interacting clouds as would be found in a galactic spiral arm. In this paper, building on previous work by

SILCC VI – Multiphase ISM structure, stellar clustering, and outflows with supernovae, stellar winds, ionizing radiation, and cosmic rays [PDF]

open access: yes, 2021
We present simulations of the multi-phase interstellar medium (ISM) at solar neighbourhood conditions including thermal and non-thermal ISM processes, star cluster formation, and feedback from massive stars: stellar winds, hydrogen ionising radiation ...

The surprisingly small impact of magnetic fields on the inner accretion flow of Sagittarius A* fueled by stellar winds [PDF]

open access: yes, 2020
We study the flow structure in 3D magnetohydrodynamic (MHD) simulations of accretion onto Sagittarius A* via the magnetized winds of the orbiting Wolf-Rayet stars.

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.
