The Massive End of the Stellar Mass Function [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We derive average flux corrections to the \texttt{Model} magnitudes of the Sloan Digital Sky Survey (SDSS) galaxies by stacking together mosaics of similar galaxies in bins of stellar mass and concentration. Extra flux is detected in the outer low surface brightness part of the galaxies, leading to corrections ranging from 0.05 to 0.32 mag for the ...

Stellar coronal mass ejections [PDF]
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 ...

Constraining the Stellar Mass Function in the Galactic Center via Mass Loss from Stellar Collisions [PDF]
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.

An HSC view of the CMASS galaxy sample. Halo mass as a function of stellar mass, size and Sérsic index [PDF]
A&A 622, A30 (2019), 2018 Aims. We wish to determine the distribution of dark matter halo masses as a function of the stellar mass and the stellar mass profile, for massive galaxies in the BOSS CMASS sample. Methods. We use grizy photometry from HSC to obtain S\'ersic fits and stellar masses of CMASS galaxies for which HSC weak lensing data is available, visually selected to ...

The Stellar Mass Components of Galaxies: Comparing Semi-Analytical Models with Observation [PDF]
Astrophys.J.712:734-745,2010, 2009 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. In particular, we compare the stellar mass functions of centrals and satellites, the relation between total stellar ...

Evolution of Mass Functions of Coeval Stars through Wind Mass Loss and Binary Interactions [PDF]
, 2015 Accurate determinations of stellar mass functions and ages of stellar populations are crucial to much of astrophysics. We analyse the evolution of stellar mass functions of coeval main sequence stars including all relevant aspects of single- and binary-star evolution.

Red Galaxy Growth and the Halo Occupation Distribution [PDF]
Astrophys.J.682:937-963,2008, 2008 We have traced the past 7 Gyr of red galaxy stellar mass growth within dark matter halos. We have determined the halo occupation distribution, which describes how galaxies reside within dark matter halos, using the observed luminosity function and clustering of 40,696 0.2

The Effect of the Remnant Mass in Estimating Stellar Mass of Galaxies [PDF]
Publications of the Astronomical Society of Japan, 2013 The definition of the galactic stellar mass estimated from the spectral energy distribution is ambiguous in the literature; whether the stellar mass includes the mass of the stellar remnants, i.e. white dwarfs, neutron stars, and black holes, is not well described. The remnant mass fraction in the total (living+remnant) stellar mass of a simple stellar

The masses and metallicities of stellar haloes reflect galactic merger histories [PDF]
, 2017 There is increasing observational and theoretical evidence for a correlation between the metallicity and the mass of the stellar halo for galaxies with Milky Way-like stellar masses. Using the Illustris cosmological hydrodynamical simulations, we find that this relationship arises because a single massive massive progenitor contributes the bulk of the ...
