Tracing the Orphan Stream to 55 kpc with RR Lyrae Stars
Branimir Sesar, Carl J. Grillmair, Judith G. Cohen +10
We report positions, velocities and metallicities of 50 ab-type RR Lyrae (RRab) stars observed in the vicinity of the Orphan stellar stream. Using about 30 RRab stars classified as…
Asteroids in GALEX: Near-ultraviolet photometry of the major taxonomic groups
Adam Waszczak, Eran O. Ofek, Shrinivas R. Kulkarni
We present ultraviolet photometry (NUV band, 180--280 nm) of 405 asteroids observed serendipitously by the Galaxy Evolution Explorer (GALEX) from 2003--2012. All asteroids in this…
Small near-Earth asteroids in the Palomar Transient Factory survey: A real-time streak-detection system
Adam Waszczak, Thomas A. Prince, Russ Laher +7
Near-Earth asteroids (NEAs) in the 1-100 meter size range are estimated to be 1,000 times more numerous than the 15,000 currently-catalogued NEAs, most of which are in…
IPAC Image Processing and Data Archiving for the Palomar Transient Factory
Russ R. Laher, Jason Surace, Carl J. Grillmair +26
The Palomar Transient Factory (PTF) is a multi-epochal robotic survey of the northern sky that acquires data for the scientific study of transient and variable astrophysical phenom…
Centaurs and Scattered Disk Objects in the Thermal Infrared: Analysis of WISE/NEOWISE Observations
James M. Bauer, Tommy Grav, Erin Blauvelt +22
The Wide-field Infrared Survey Explorer (WISE) observed 52 Centaurs and Scattered Disk Objects in the thermal infrared, including the 15 discoveries that were new. We present analy…
Main-belt comets in the Palomar Transient Factory survey: I. The search for extendedness
Adam Waszczak, Eran O. Ofek, Oded Aharonson +7
Cometary activity in main-belt asteroids probes the ice content of these objects and provides clues to the history of volatiles in the inner solar system. We search the Palomar Tra…
