Long-term Photometric Behavior of Outbursting AM CVn Systems
David Levitan, Paul J. Groot, Thomas A. Prince +5
The AM CVn systems are a class of He-rich, post-period minimum, semi-detached, ultra-compact binaries. Their long-term light curves have been poorly understood due to the few syste…
Stacking the Invisibles: A Guided Search for Low-Luminosity Milky Way Satellites
B. Sesar, S. R. Banholzer, J. G. Cohen +9
Almost every known low-luminosity Milky Way dwarf spheroidal (dSph) satellite galaxy contains at least one RR Lyrae star. Assuming that a fraction of distant (60 < d_{helio} < 100…
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…
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…
PTF1 J191905.19+481506.2 - A Partially Eclipsing AM CVn System Discovered in the Palomar Transient Factory
David Levitan, Thomas Kupfer, Paul J. Groot +11
We report on PTF1 J191905.19+481506.2, a newly discovered, partially eclipsing, outbursting AM CVn system found in the Palomar Transient Factory synoptic survey. This is only the s…
Connection between optical and gamma-ray variability in blazars
T. Hovatta, V. Pavlidou, O. G. King +14
We use optical data from the Palomar Transient Factory (PTF) and the Catalina Real-Time Transient Survey (CRTS) to study the variability of gamma-ray detected and non-detected obje…
