Spectroscopic Properties of Cool Stars (SPOCS). I. 1040 F, G, and K Dwarfs from Keck, Lick, and AAT Planet Search Programs
- J. Valenti, D. Fischer
- Physics, Geology
- 1 July 2005
We present a uniform catalog of stellar properties for 1040 nearby F, G, and K stars that have been observed by the Keck, Lick, and AAT planet search programs. Fitting observed echelle spectra with…

- 27 December 2010
We present a database of well-determined orbital parameters of exoplanets, and their host stars’ properties. This database comprises spectroscopic orbital elements measured for 427 planets orbiting…
The Occurrence and Mass Distribution of Close-in Super-Earths, Neptunes, and Jupiters
The occurrence rate of close-in planets (with orbital periods less than 50 days), based on precise Doppler measurements of 166 Sun-like stars, is reported, indicating that theoretical models of planet formation predict a deficit of planets in the domain from 5 to 30 Earth masses and with orbital periods under 50 days are in fact well populated.
Discovery of two young brown dwarfs in an eclipsing binary system

- 16 March 2006
This work reports the discovery of a brown-dwarf eclipsing binary system, in the Orion Nebula star-forming region, from which direct measurements of mass and radius establish both objects as brown dwarfs, and finds that the less-massive brown dwarf is the hotter of the pair.
The N2K Consortium. II. A Transiting Hot Saturn around HD 149026 with a Large Dense Core
- B. Sato, D. Fischer, D. Minniti
- Physics, Geology
- 30 June 2005
Doppler measurements from Subaru and Keck have revealed radial velocity variations in the V = 8.15, G0 IV star HD 149026 consistent with a Saturn-mass planet in a 2.8766 day orbit. Photometric…
