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…
Asteroid Spin-Rate Study using the Intermediate Palomar Transient Factory
Chan-Kao Chang, Wing-Huen Ip, Hsing-Wen Lin +10
Two dedicated asteroid rotation-period surveys have been carried out using data taken on January 6-9 and February 20-23 of 2014 by the Intermediate Palomar Transient Factory (iPTF)…
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…
Asteroid lightcurves from the Palomar Transient Factory survey: Rotation periods and phase functions from sparse photometry
Adam Waszczak, Chan-Kao Chang, Eran O. Ofek +10
We fit 54,296 sparsely-sampled asteroid lightcurves in the Palomar Transient Factory to a combined rotation plus phase-function model. Each lightcurve consists of 20+ observations…
Sublimation-Driven Activity in Main-Belt Comet 313P/Gibbs
Henry H. Hsieh, Olivier Hainaut, Bojan Novakovic +15
We present an observational and dynamical study of newly discovered main-belt comet 313P/Gibbs. We find that the object is clearly active both in observations obtained in 2014 and…
A New Large Super-Fast Rotator: (335433) 2005 UW163
Chan-Kao Chang, Adam Waszczak, Hsing-Wen Lin +5
Asteroids of size larger than 150 m generally do not have rotation periods smaller than 2.2 hours. This spin cutoff is believed to be due to the gravitationally bound rubble-pile s…
313 new asteroid rotation periods from Palomar Transient Factory observations
Chan-Kao Chang, Wing-Huen Ip, Hsing-Wen Lin +11
A new asteroid rotation period survey have been carried out by using the Palomar Transient Factory (PTF). Twelve consecutive PTF fields, which covered an area of 87 deg in the…
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…
Asteroid rotation periods from the Palomar Transient Factory survey
D. Polishook, E. O. Ofek, A. Waszczak +17
The Palomar Transient Factory (PTF) is a synoptic survey designed to explore the transient and variable sky in a wide variety of cadences. We use PTF observations of fields that we…
