On the Origin of Stellar Masses [PDF]
The Astrophysical Journal, 2011 It has been a longstanding problem to determine, as far as possible, the characteristic masses of stars in terms of fundamental constants; the almost complete invariance of this mass as a function of the star-forming environment suggests that this should

Stellar Mass Calibrations for Local Low-mass Galaxies
The Astrophysical JournalThe stellar masses of galaxies are measured from integrated light via several methods—however, few of these methods were designed for low-mass ( M _⋆ ≲ 10 ^8 M _⊙ ) “dwarf” galaxies, whose properties (e.g., stochastic star formation, low metallicity ...

Variation in the stellar mass function along stellar streams [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Stellar streams are the inevitable end product of star cluster evolution, with the properties of a given stream being related to its progenitor. We consider how the dynamical history of a progenitor cluster, as traced by the evolution of its stellar mass function, is reflected in the resultant stream.

Stellar coronal mass ejections
Serbian Astronomical Journal, 2022 Stellar coronal mass ejections (CMEs) are a growing research field, especially during the past decade. The large number of so far detected exoplanets raises the open question for the CME activity of stars, as CMEs may strongly affect exoplanetary atmospheres.

No Tension: JWST Galaxies at $z > 10$ Consistent with Cosmological Simulations
The Open Journal of Astrophysics, 2023 Recent observations by JWST have uncovered galaxies in the very early Universe via the JADES and CEERS surveys. These galaxies have been measured to have very high stellar masses with substantial star formation rates.

Proceedings of the International Astronomical Union, 2008 AbstractIt has been known for some time now that rapidly-rotating solar-like stars possess the stellar equivalent of solar prominences. These may be three orders of magnitude more massive than their solar counterparts, and their ejection from the star may form a significant contribution to the loss of angular momentum and mass in the stellar wind.

STELLAR MASS DEPENDENT DISK DISPERSAL [PDF]
The Astrophysical Journal, 2009 We use published optical spectral and IR excess data from nine young clusters and associations to study the stellar mass dependent dispersal of circumstellar disks. All clusters older than ~3 Myr show a decrease in disk fraction with increasing stellar mass for Solar to higher mass stars.

THE MASS DISTRIBUTION OF STELLAR-MASS BLACK HOLES [PDF]
The Astrophysical Journal, 2011 We perform a Bayesian analysis of the mass distribution of stellar-mass black holes using the observed masses of 15 low-mass X-ray binary systems undergoing Roche lobe overflow and five high-mass, wind-fed X-ray binary systems. Using Markov Chain Monte Carlo calculations, we model the mass distribution both parametrically---as a power law, exponential,

The Astronomical Journal, 2023 High-precision stellar masses and radii measured directly from binaries can effectively calibrate stellar models. However, such a database containing full spectral types and a large range of metallicity is still not fully established. A continuous effort

Can Protostellar Outflows Set Stellar Masses?
The Astrophysical Journal, 2023 The opening angles of some protostellar outflows appear too narrow to match the expected core–star mass efficiency (SFE) = 0.3–0.5, if the outflow cavity volume traces outflow mass, with a conical shape and a maximum opening angle near 90°.
