The distribution of low-mass stars in the Galactic disc
We quantify the complex interdependence of stellar binarity, the stellar mass-luminosity relation, the mass function, the colour-magnitude relation and Galactic disc structure, all of which must beExpand
A Universal Mass Profile for Dwarf Spheroidal Galaxies
We apply the Jeans equation to estimate masses for eight of the brightest dwarf spheroidal (dSph) galaxies. For Fornax, the dSph with the largest kinematic data set, we obtain a model-independentExpand
The mass distribution in the galactic disc – II. Determination of the surface mass density of the galactic disc near the Sun
Les donnees photometriques et spectroscopiques pour un echantillon de naines K en direction du pole galactique sud sont analysees en utilisant la technique de modelisation des fonctions deExpand
The mass distribution in the galactic disc – I. A technique to determine the integral surface mass density of the disc near the Sun
Les donnees d'observations requises pour determiner la densite de masse superficielle sont la fonction de distribution observee des vitesses et des distances pour un echantillon d'etoiles s'etendantExpand
The galactic disk surface mass density and the Galactic force K(z) at z = 1. 1 kiloparsecs
A set of distance and velocity data previously obtained and analyzed is rediscussed to determine the surface mass density of the Galactic disk. These data reliably determine the integral surface massExpand
Substructure revealed by RR Lyraes in SDSS Stripe 82
We present an analysis of the substructure revealed by RR Lyraes in Sloan Digital Sky Survey Stripe 82, which covers 2°5 in declination on the celestial equator over the right ascension range α = 20Expand
The Luminosity Function of the Milky Way Satellites
We quantify the detectability of stellar Milky Way satellites in the Sloan Digital Sky Survey (SDSS) Data Release 5. We show that the effective search volumes for the recently discoveredExpand
The Kinematics, Orbit, and Survival of the Sagittarius Dwarf Spheroidal Galaxy
The Sagittarius galaxy (Sgr), the closest satellite galaxy of the Milky Way, has survived for many orbits about the Galaxy. Extant numerical calculations modeled this galaxy as a system with aExpand
Chemistry and Kinematics in the Solar Neighborhood: Implications for Stellar Populations and for Galaxy Evolution
The immediate Solar neighborhood should be a fair sample of the local Galaxy. However, the chemical abundance distribution of long-lived disk stars very near the Sun contains a factor of five to tenExpand
