▪ Abstract Eight extrasolar planet candidates have now been identified, all revealed by Keplerian Doppler shifts in their host stars. The masses (m sin i) lie between 0.5 and 7 MJUP, and the semimajor axes are less than 2.1 astronomical units (AU). Doppler detectability favors high masses and small orbits, and improvements will render Saturn masses detectable within a few years. The substellar mass function (dN/dM) for companions is roughly flat from 70 down to 10 MJUP, but it exhibits a sharp… Expand
Extrasolar Planets around Main Sequence Stars
The mass distribution of substellar companions exhibits a steep rise for masses below 5 MJ. Thus, the 14 companions having Msin i = 0.5 { 5 MJ are considered the best candidate planets around mainExpand
Two New Candidate Planets in Eccentric Orbits
Doppler measurements of two G-type main-sequence stars, HD 210277 and HD 168443, reveal Keplerian variations that imply the presence of companions with masses (M sin i) of 1.28 and 5.04 MJ (where MJExpand
Doppler Detection of Extrasolar Planets
We have measured the radial velocities of 540 G and K main sequence stars with a precision of 3−10 ms −1 using the Lick and Keck echelle spectrometers. We had detected 6 companions that have m sin iExpand
Extrasolar Planets: Techniques, Results, and the Future
To date, we have not obtained direct images of planets around other stars. However, the small-amplitude Keplerian motion of stars, presumably caused by the gravitational forces exerted them byExpand
Discovery of a planet orbiting a binary star system from gravitational microlensing
The properties of the recently discovered extrasolar planets were not anticipated by theoretical work on the formation of planetary systems, most models for which were developed to explain our SolarExpand
Binary star systems and extrasolar planets
For ten years, planets around stars similar to the Sun have been discovered, confirmed, and their properties studied. Planets have been found in a variety of environments previously thoughtExpand
Four New Planets Orbiting Metal-enriched Stars*
We report the detection of four new extrasolar planets from the Anglo-Australian Planet Search orbiting the metal-enriched stars HD 73526, HD 76700, HD 30177, and HD 2039. The planetary companion ofExpand
Extra-solar planets
The discovery of the first extra-solar planet surrounding a main-sequence star was announced in 1995, based on very precise radial velocity (Doppler) measurements. A total of 34 such planets wereExpand
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 —t to both companionsExpand
Two New Planets from the Anglo-Australian Planet Search
Precise Doppler measurements from the Anglo-Australian Telescope (AAT) UCLES spectrometer reveal periodic Keplerian velocity variations in the stars HD 160691 and HD 27442. HD 160691 has a period ofExpand

TLDR
The sensitivities of astrometric and radial velocity searches for extrasolar planets are strongly dependent on planetary masses and orbits, and radiative hydrodynamic models of protoplanetary disks around low-mass stars show that Jupiter-like planets should form at distances that are only weakly dependent on the stellar mass.
