The discovery of the first methane brown dwarf provides a framework for describing the important advances in both fundamental physics and astrophysics that are due to the study of companions of stars. I present a few highlights of the history of this subject along with details of the discovery of the brown dwarf Gliese 229B. The nature of companions of stars is discussed with an attempt to avoid biases induced by anthropocentric nomenclature. With the newer types of remote reconnaissance of… 



Discovery of a cool brown dwarf

The discovery of a probable companion to the nearby star G1229, with no more than onetenth the luminosity of the least luminous hydro-gen-burning star, is reported, concluding that the companion is a brown dwarf with a temperature of less than 1,200 K, and a mass ∼20–50 times that of Jupiter.

A low-temperature companion to a white dwarf star

We have discovered an infrared object located about 120 AU from the white dwarf GD165. With the exception of the possible brown dwarf companion to Giclas 29–38 which we reported last year1, the

Discovery of a brown dwarf in the Pleiades star cluster

BROWN dwarfs are cool star-like objects that have insufficient mass to maintain stable nuclear fusion in their interiors. Although brown dwarfs are not stars, they are expected to form in the same

From 51 Peg to Earth-type planets

Direct Imaging of Multiple Planets Orbiting the Star HR 8799

High-contrast observations with the Keck and Gemini telescopes have revealed three planets orbiting the star HR 8799, with projected separations of 24, 38, and 68 astronomical units.

A coronagraphic search for brown dwarfs around nearby stars

Brown dwarf companions have been searched for around stars within 10 pc of the Sun using the Johns-Hopkins University Adaptive Optics Coronagraph (AOC), a stellar coronagraph with an image

Images of a fourth planet orbiting HR 8799

The HR 8799 planetary system, with its four young giant planets and known cold/warm debris belts, is a unique laboratory in which to study the formation and evolution of giant planets at wide (>10 au) separations.

An expanded set of brown dwarf and very low mass star models

We present in this paper updated and improved theoretical models of brown dwarfs and late M dwarfs. The evolution and characteristics of objects between 0.01 and 0.2 solar mass are exhaustively

Formation and evolution of planetary systems: the impact of high-angular resolution optical techniques

The direct images of giant extrasolar planets recently obtained around several main sequence stars represent a major step in the study of planetary systems. These high-dynamic range images are among

A Jupiter-mass companion to a solar-type star

The presence of a Jupiter-mass companion to the star 51 Pegasi is inferred from observations of periodic variations in the star's radial velocity. The companion lies only about eight million
