SPECTROSCOPIC PROPERTIES OF COOL STARS (SPOCS). I. 1040 F, G, AND K DWARFS FROM KECK, LICK, AND AAT PLANET SEARCH PROGRAMS
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…
The Planet-Metallicity Correlation
We have recently carried out spectral synthesis modeling to determine Teff, log g, v sin i, and [Fe/H] for 1040 FGK-type stars on the Keck, Lick, and Anglo-Australian Telescope planet search…
The Pan-STARRS1 Surveys
Pan-STARRS1 has carried out a set of distinct synoptic imaging sky surveys including the $3\pi$ Steradian Survey and the Medium Deep Survey in 5 bands ($grizy_{P1}$). The mean 5$\sigma$ point source…
Spectroscopy Made Easy: A New Tool for Fitting Observations with Synthetic Spectra
We describe a new software package that may be used to determine stellar and atomic parameters by matching observed spectra with synthetic spectra generated from parameterized atmospheres. A…
Visible and Near Infrared Atlas of the Arcturus Spectrum 3727-9300 A
The Exoplanet Orbit Database
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 N2K Consortium. II. A Transiting Hot Saturn around HD 149026 with a Large Dense Core
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…
Discovery of two young brown dwarfs in an eclipsing binary system
TLDR
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 Occurrence and Mass Distribution of Close-in Super-Earths, Neptunes, and Jupiters
TLDR
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.
The Pan-STARRS1 Database and Data Products
This paper describes the organization of the database and the catalog data products from the Pan-STARRS1 $3\pi$ Steradian Survey. The catalog data products are available in the form of an SQL-based…
