ORBITS, DISTANCE, AND STELLAR MASSES OF THE MASSIVE TRIPLE STAR σ ORIONIS [PDF]

, 2016
We present interferometric observations of the σ Orionis triple system using the CHARA Array, NPOI, and VLTI. Using these measurements, we spatially resolve the orbit of the close spectroscopic binary (Aa,Ab) for the first time and present a revised ...

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.

The luminosity and stellar mass Fundamental Plane of early-type galaxies [PDF]

, 2009
From a sample of ~50000 early-type galaxies from the SDSS, we measured the traditional Fundamental Plane in four bands. We then replaced luminosity with stellar mass, and measured the "stellar mass" FP.

STELLAR MASSES AND STAR FORMATION RATES FOR 1 M GALAXIES FROM SDSS+WISE [PDF]

, 2015
We combine Sloan Digitital Sky Survey (SDSS) and WISE photometry for the full SDSS spectroscopic galaxy sample, creating spectral energy distributions (SEDs) that cover λ = 0.4–22 μm for an unprecedentedly large and comprehensive sample of 858,365 ...

Benchmarking pre-main sequence stellar evolutionary tracks using disk-based dynamical stellar masses

Astronomy & Astrophysics
Stellar masses are a fundamental property to understand models of pre-main sequence evolution, but their values derived from Hertzsprung–Russell (HR) diagrams are strongly model dependent.

Breaking down the link between luminous and dark matter in massive galaxies

, 2011
We present a study on the clustering of a stellar mass selected sample of galaxies with stellar masses M*>10^10Msol at redshifts 0 ...

THE SPITZER SURVEY OF STELLAR STRUCTURE IN GALAXIES (S4G): STELLAR MASSES, SIZES, AND RADIAL PROFILES FOR 2352 NEARBY GALAXIES [PDF]

, 2015
The Spitzer Survey of Stellar Structure in Galaxies is a volume, magnitude, and size-limited survey of 2352 nearby galaxies with deep imaging at 3.6 and 4.5 μm.

The Stellar Ages and Masses of Short GRB Host Galaxies: Investigating the Progenitor Delay Time Distribution and the Role of Mass and Star Formation in the Short GRB Rate

, 2010
[Abridged] We present optical and NIR observations of 19 short GRB host galaxies, aimed at measuring their stellar masses and population ages. The goals of this study are to evaluate whether short GRBs track the stellar mass distribution of galaxies, to ...

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.
