Since the beginning of precise Doppler surveys, which have had stunning success in detecting extrasolar planetary companions, one surprising enigma has emerged: the relative paucity of spectroscopic binaries where the secondary mass lies in between the stellar and planetary mass regime. This gap in the mass function for close-in (a < 3-4 AU) companions to solar-type stars is generally referred to as the "brown dwarf desert." Here we report the detection of a companion to HD 137510 (G0 IV), with… 

The SOPHIE search for northern extrasolar planets . I. A companion around HD 16760 with mass close to the planet/brown-dwarf transition

We report on the discovery of a substellar companion or a massive Jupiter orbiting the G5V star HD 16760 using the spectrograph SOPHIE installed on the OHP 1.93-m telescope. Characteristics and

The SOPHIE search for northern extrasolar planets - IX. Populating the brown dwarf desert

Radial velocity planet search surveys of nearby solar-type stars have shown a strong scarcity of brown dwarf companions within similar to 5 AU. There is presently no comprehensive explanation for


We report the detection of a brown dwarf candidate orbiting the metal-rich K dwarf HD 91669, based on radial-velocity data from the McDonald Observatory Planet Search. HD 91669b is a substellar

Fourteen New Companions from the Keck and Lick Radial Velocity Survey Including Five Brown Dwarf Candidates

We present radial velocities for 14 stars on the California and Carnegie Planet Search target list that reveal new companions. One star, HD 167665, was fit with a definitive Keplerian orbit leading

A substellar component orbiting the F-star 30 Arietis B

Context. Most current radial velocity planet search programs have concentrated on stars of one solar mass. Our knowledge on the frequency of giant planets and brown dwarf companions to more massive

A Massive Substellar Companion to the Massive Giant HD 119445

We detected a brown dwarf-mass companion around the intermediate-mass giant star HD 119445 (G6III) using the Doppler technique. This discovery is the first result from a KoreanJapanese planet search

A Probable Close Brown Dwarf Companion To GJ 1046 (M 2.5V)

Context. Brown dwarf companions to stars at separations of a few AU or less are rare objects, and none have been found so far around early-type M dwarfs (M 0V−M 5V). With GJ 1046 (M 2.5V), a strong


We present precise radial velocity data for the metal-rich star HD 45350 collected with the Harlan J. Smith (HJS) 2.7 m telescope and the Hobby-Eberly Telescope (HET) at McDonald Observatory. This


Precise radial velocities from the Anglo-Australian Telescope (AAT) confirm the presence of a rare short-period planet around the K0 giant HD 121056. An independent two-planet solution using the AAT

Exploring the Frequency of Close-in Jovian Planets around M Dwarfs

We discuss our high-precision radial velocity results of a sample of 90 M dwarfs observed with the Hobby-Eberly Telescope and the Harlan J. Smith 2.7 m Telescope at McDonald Observatory, as well as



The unseen companion of HD114762: a probable brown dwarf

BROWN dwarfs are substellar objects with too little mass to ignite hydrogen in their cores. Despite considerable effort to detect brown dwarfs astrometrically1–4, photometrically4–9, and

Two Substellar Companions Orbiting HD 168443

Precise Doppler measurements during 4.4 yr from the Keck/HIRES spectrometer reveal two superimposed Keplerian velocity variations for HD 168443 (G6 IV). A simultaneous orbital fit to both companions

Constraints on the Companion Object to HD 114762

High-precision radial velocity observations of the candidate planetary system HD 114762 are presented. The new data confirm Latham et al.'s discovery (1989, Nature, 339) of the binary nature of the

Ten Low-Mass Companions from the Keck Precision Velocity Survey

Ten new companions have emerged from the Keck precision Doppler velocity survey, with minimum (M sin i) masses ranging from 0.8 MJUP to 0.34 M☉. Five of these are planet candidates with M sin i < 12

The Abundance Distribution in the Extrasolar-Planet Host Star HD 19994

Abundances of 22 elements have been determined from a high-resolution, high signal-to-noise spectrum of HD 19994, a star recently announced as harboring an extrasolar planet. A detailed spectroscopic

At the Mount John University Observatory relative radial velocities of solar-type stars have been obtained with a characteristic random error of 55 m s −1 using a fiber-fed echelle system and digital

Substellar Companions to Main-Sequence Stars: No Brown Dwarf Desert at Wide Separations

We use three field L and T dwarfs that were discovered to be wide companions to known stars by the Two Micron All-Sky Survey to derive a preliminary brown dwarf companion frequency. Observed L and T
