The Astrophysical Journal, 2023 We investigate the mass–metallicity relationship of star-forming galaxies by analyzing the absorption line spectra of ∼200,000 galaxies in the Sloan Digital Sky Survey.

Constraining the Stellar Mass Function in the Galactic Center via Mass Loss from Stellar Collisions
Advances in Astronomy, 2011 The dense concentration of stars and high-velocity dispersions in the Galactic center imply that stellar collisions frequently occur. Stellar collisions could therefore result in significant mass loss rates.

The Astrophysical Journal, 2023 The assembly of galaxies over cosmic time is tightly connected to the assembly of their host dark matter halos. We investigate the stellar mass growth history and the chemical enrichment history of central galaxies in the Sloan Digital Sky Survey Mapping

Precise Stellar Mass and Mass-Luminosity Data [PDF]
Symposium - International Astronomical Union, 1997 Recent progress in observing and data reduction methods for precise mass and mass-luminosity determinations in binary systems are briefly reviewed. The foundations appear to have been laid for a new burst of accurate data. Detailed model simulations of the individual systems are the best way to use these data to critically test the theoretical models ...

Extragalactic Constraints on the Initial Mass Function [PDF]
, 2008 The local stellar mass density is observed to be significantly lower than the value obtained from integrating the cosmic star formation history (SFH), assuming that all the stars formed with a Salpeter initial mass function (IMF).

Mass loss and stellar superwinds [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017 Mass loss bridges the gap between massive stars and supernovae (SNe) in two major ways: (i) theoretically, it is the amount of mass lost that determines the mass of the star prior to explosion and (ii) observations of the circumstellar material around SNe may teach us the type of progenitor that made the SN.

The Stellar Mass Components of Galaxies: Comparing Semi-Analytical Models with Observation [PDF]
, 2010 We compare the stellar masses of central and satellite galaxies predicted by three independent semianalytical models with observational results obtained from a large galaxy group catalogue constructed from the Sloan Digital Sky Survey.

Satellite galaxies in the Illustris-1 simulation: anisotropic locations around relatively isolated hosts [PDF]
, 2019 We investigate the locations of satellite galaxies in the z = 0 redshift slice of the hydrodynamical Illustris-1 simulation. As expected from previous work, the satellites are distributed anisotropically in the plane of the sky, with a preference for ...

Radio observations of stellar mass loss [PDF]
Symposium - International Astronomical Union, 1979 A program to search for steady-state thermal emissions from stars has been in progress for several years in Canada (Purton 1976). In this program we have specifically excluded flaring objects (such as β Lyr or HR1099) where non-thermal emission is probably responsible.
