The amount of mass contained in low-mass objects is investigated anew. Instead of using a mass-luminosity relation to convert a luminosity function to a mass function, I predict the mass-luminosity relation from assumed mass functions and the luminosity functions of Jahreiss & Wielen (1997) and Gould et al (1997). Comparison of the resulting mass-luminosity relations with data from binary stars constrains the permissible mass functions. If the mass function is assumed to be a power law, the… Expand

The G-dwarf problem in the Galaxy
Abstract This paper has two parts: one about observational constraints, and the other about chemical evolution models. In the first part, the empirical differential metallicity distribution (EDMD) isExpand
MICROLENSING SIGNATURE OF A WHITE DWARF POPULATION IN THE GALACTIC HALO
Microlensing and pixel-lensing surveys play a fundamental role in the searches for galactic dark matter and in the study of the galactic structure. Recent observations suggest the presence of aExpand

TLDR
It is suggested that the secondary of HD 10697 is probably a brown dwarf, orbiting around its parent star at a distance of 2 AU, implying a mass of 38+/-13 MJ for the unseen companion. Expand
Astrophysics in 1999
The year 1999 saw the arrival of a star with three planets, a universe with three parameters, and a solar corona that could be heated at least three ways. In addition, there were at least threeExpand

The mass-luminosity relation for stars of mass 1.0 to 0.08 solar mass
Mass-luminosity relations determined at IR wavelengths are presented for stars with masses 1.0 to 0.08 solar mass. Using IR speckle imaging techniques on a sample of nearby binaries, we have beenExpand
Disk M Dwarf Luminosity Function From HST Star Counts
We study a sample of 257 Galactic disk M dwarfs (8 12 (M<0.25 \ms), decreasing by a factor \gsim 3 by M_V~14 (M~0.14\ms). This decrease in the LF is in good agreement with the ground-basedExpand
