Calibration of the MEarth Photometric System: Optical Magnitudes and Photometric Metallicity Estimates for 1802 Nearby M-dwarfs
(American Astronomical Society, 2016)The MEarth Project is a photometric survey systematically searching the smallest stars nearest to the Sun for transiting rocky planets. Since 2008, MEarth has taken approximately two million images of 1844 stars suspected ... -
Colors of 2625 Quasars at 0 < z < 5 Measured in the Sloan Digital Sky Survey Photometric System
(IOP Publishing, 2001)We present an empirical investigation of the colors of quasars in the Sloan Digital Sky Survey (SDSS) photometric system. The sample studied includes 2625 quasars with SDSS photometry: 1759 quasars found during SDSS ... -
A Dark Energy Camera Search for an Optical Counterpart to the First Advanced Ligo Gravitational Wave Event Gw150914
(American Astronomical Society, 2016)We report initial results of a deep search for an optical counterpart to the gravitational wave event GW150914, the first trigger from the Advanced LIGO gravitational wave detectors. We used the Dark Energy Camera (DECam) ... -
A Decam Search for an Optical Counterpart to the Ligo Gravitational-Wave Event Gw151226
(American Astronomical Society, 2016)We report the results of a Dark Energy Camera (DECam) optical follow-up of the gravitational wave (GW) event GW151226, discovered by the Advanced LIGO detectors. Our observations cover 28.8 deg2 of the localization region ... -
The First Data Release of the Sloan Digital Sky Survey
(IOP Publishing, 2003)The Sloan Digital Sky Survey (SDSS) has validated and made publicly available its First Data Release. This consists of 2099 deg2 of five-band (u, g, r, i, z) imaging data, 186,240 spectra of galaxies, quasars, stars and ... -
The Occurrence of Potentially Habitable Planets Orbiting M Dwarfs Estimated From the Full Kepler Dataset and an Empirical Measurement of the Detection Sensitivity
(IOP Publishing, 2015)We present an improved estimate of the occurrence rate of small planets orbiting small stars by searching the full four-year Kepler data set for transiting planets using our own planet detection pipeline and conducting ... -
The Occurrence Rate of Small Planets Around Small Stars
(IOP Publishing, 2013)We use the optical and near-infrared photometry from the Kepler Input Catalog to provide improved estimates of the stellar characteristics of the smallest stars in the Kepler target list. We find 3897 dwarfs with temperatures ... -
Planetary Candidates Observed by Kepler III: Analysis of the First 16 Months of Data
(IOP Publishing, 2013)New transiting planet candidates are identified in 16 months (2009 May-2010 September) of data from the Kepler spacecraft. Nearly 5000 periodic transit-like signals are vetted against astrophysical and instrumental false ... -
The Second Data Release of the Sloan Digital Sky Survey
(IOP Publishing, 2004)The Sloan Digital Sky Survey (SDSS) has validated and made publicly available its Second Data Release. This data release consists of 3324 deg2 of five-band (ugriz) imaging data with photometry for over 88 million unique ... -
The Sixth Data Release of the Sloan Digital Sky Survey
(IOP Publishing, 2008)This paper describes the Sixth Data Release of the Sloan Digital Sky Survey. With this data release, the imaging of the northern Galactic cap is now complete. The survey contains images and parameters of roughly 287 million ... -
Sloan Digital Sky Survey Imaging of Low Galactic Latitude Fields: Technical Summary and Data Release
(IOP Publishing, 2004)The Sloan Digital Sky Survey (SDSS) mosaic camera and telescope have obtained five-band optical-wavelength imaging near the Galactic plane outside of the nominal survey boundaries. These additional data were obtained during ... -
Sloan Digital Sky Survey Standard Star Catalog for Stripe 82: The Dawn of Industrial 1% Optical Photometry
(IOP Publishing, 2007)We describe a standard star catalog constructed using multiple SDSS photometric observations (at least four per band, with a median of 10) in the ugriz system. The catalog includes 1.01 million nonvariable unresolved objects ... -
The Third Data Release of the Sloan Digital Sky Survey
(IOP Publishing, 2005)This paper describes the Third Data Release of the Sloan Digital Sky Survey (SDSS). This release, containing data taken up through 2003 June, includes imaging data in five bands over 5282 deg2, photometric and astrometric ...
