The structure of accreted stellar streams [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT Many of the Milky Way’s globular clusters are likely accreted from satellite galaxies that have long since merged with the Milky Way. When these globular clusters are susceptible to tidal disruption, this process likely starts already inside the parent satellite leading to an early stellar stream within the satellite.

The Mass Accretion Rate and Stellar Properties in Class I Protostars
The Astrophysical Journal, 2023 Stars collect most of their mass during the protostellar stage, yet the accretion luminosity and stellar parameters, which are needed to compute the mass accretion rate, are poorly constrained for the youngest sources.

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 ...

Stellar capture by an accretion disc [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 Long-term evolution of a stellar orbit captured by a massive galactic center via successive interactions with an accretion disc has been examined. An analytical solution describing evolution of the stellar orbital parameters during the initial stage of the capture was found.

Disk Accretion and the Stellar Birthline [PDF]
The Astrophysical Journal, 1997 We present a simplified analysis of some effects of disk accretion on the early evolution of fully convective, low-mass pre-main-sequence stars. Our analysis builds on the previous seminal work of Stahler, but it differs in that the accretion of material occurs over a small area of the stellar surface, such as through a disk or magnetospheric accretion

X-Shooter study of accretion in Chamaeleon I: II. A steeper increase of accretion with stellar mass for very low mass stars? [PDF]
, 2017 The dependence of the mass accretion rate on the stellar properties is a key constraint for star formation and disk evolution studies. Here we present a study of a sample of stars in the Chamaeleon I star forming region carried out using the VLT/X ...

Accretion from Stellar Winds [PDF]
International Astronomical Union Colloquium, 1988 AbstractRecent calculations have demonstrated that accretion from a stellar wind is very probably unsteady. The average rate of accretion of angular momentum is lower by about a factor 5 than the rate at which angular momentum is deposited into the Bondi-Hoyle accretion cylinder.
