The SILCC project - III. Regulation of star formation and outflows by stellar winds and supernovae [PDF]
, 2016 We study the impact of stellar winds and supernovae on the multiphase interstellar medium using three-dimensional hydrodynamical simulations carried out with FLASH. The selected galactic disc region has a size of (500 pc)(2) x +/- 5 kpc and a gas surface

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

Morphology of Hydrodynamic Winds: A Study of Planetary Winds in Stellar Environments [PDF]
Astrophysical Journal, 2018 Bathed in intense ionizing radiation, close-in gaseous planets undergo hydrodynamic atmospheric escape, which ejects the upper extent of their atmospheres into the interplanetary medium.

The effects of stellar winds and magnetic fields on exoplanets [PDF]
, 2013 The great majority of exoplanets discovered so far are orbiting cool, low-mass stars whose properties are relatively similar to the Sun. However, the stellar magnetism of these stars can be significantly different from the solar one, both in topology and

The Dispersion and Rotation Measure of Supernova Remnants and Magnetized Stellar Winds: Application to Fast Radio Bursts [PDF]
Astrophysical Journal, 2018 Recent studies of fast radio bursts (FRBs) have led to many theories associating them with young neutron stars. If this is the case, then the presence of supernova ejecta and stellar winds provides a changing dispersion measure (DM) and rotation measure (

Stellar Winds Pump the Heart of the Milky Way [PDF]
Astrophysical Journal, 2019 The central supermassive black hole of the Milky Way, Sgr A*, accretes at a very low rate making it a very underluminous galactic nucleus. Despite the tens of Wolf–Rayet stars present within the inner parsec supplying ∼10−3 M⊙ yr−1 in stellar winds, only

Erosion of an exoplanetary atmosphere caused by stellar winds [PDF]
Astronomy & Astrophysics, 2019 Aims.We present a formalism for a first-order estimation of the magnetosphere radius of exoplanets orbiting stars in the range from 0.08 to 1.3M⊙. With this radius, we estimate the atmospheric surface that is not protected from stellar winds.

Hydrodynamic simulations of the inner accretion flow of Sagittarius A* fuelled by stellar winds [PDF]
, 2018 We present Athena++ grid-based, hydrodynamic simulations of accretion onto Sagittarius A* via the stellar winds of the $\sim 30$ Wolf-Rayet stars within the central parsec of the galactic center.

The relative impact of photoionizing radiation and stellar winds on different environments [PDF]
, 2018 Photoionizing radiation and stellar winds from massive stars deposit energy and momentum into the interstellar medium (ISM). They might disperse the local ISM, change its turbulent multi-phase structure, and even regulate star formation.

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