BROWN dwarfs lie in the mass range between the most massive Jupiter-like planets and the least massive stars. They are much less luminous than stars, and so may provide a fraction of the baryonic dark matter in our Galaxy. Only one unambiguous detection of a brown dwarf has been made to ...
Brown Dwarfs (BDs) are substellar objects in the mass range between 13 and 80 Jupiter masses approximately. They are unable to sustain hydrogen fusion in their cores, and they represent the link between the lowest mass stars (M-dwarfs) and (exo-)planets. BDs together with very low-mass M...
Synonyms of brown dwarf : a celestial object that is much smaller than a normal star and has insufficient mass to sustain nuclear fusion but that is hot enough to radiate energy especially at infrared wavelengths Examples of brown dwarf in a Sentence Recent Examples on the Web Examples are ...
In this thesis I will present optical and near-infrared photometric and spectroscopic observations of an evolved field brown dwarf binary pair and of populations of low-mass stars in high-mass young stellar clusters and will compare them to stellar and substellar theoretical model predictions. Epsilo...
Brown dwarfs, so named by American astronomer Jill Tarter in 1975, range in mass between the most massive planets and the least massive stars, about 0.002 to 0.08 times the mass of the Sun. Roughly 90 percent of the material in the universe is unaccounted for. Since it cannot be seen, ...

Even though, for most proto-brown dwarf conditions, 50% of the initial deuterium will burn if the object's mass is similar to(13.0 +/- 0.8) M-J, the full range of possibilities is significantly broader. For models ranging from zero-metallicity to more than three times solar metallicity, ...
We have focused on the properties of the first two brown dwarfs discovered, namely Teide 1 and Gl229B, to estimate the sensitivity of DENIS/2MASS to this new kind of object. The privileged photometric band is J, because it sets the limit for the faintest brown dwarfs that can be ...
