Properties and Evolution of the Redback Millisecond Pulsar Binary PSR J2129-0429
Eric C. Bellm, David L. Kaplan, Rene P. Breton +19
PSR J2129-0429 is a "redback" eclipsing millisecond pulsar binary with an unusually long 15.2 hour orbit. It was discovered by the Green Bank Telescope in a targeted search of unid…
The SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Quasar Target Selection
Adam D. Myers, Nathalie Palanque-Delabrouille, Abhishek Prakash +34
As part of the Sloan Digital Sky Survey IV the extended Baryon Oscillation Spectroscopic Survey (eBOSS) will improve measurements of the cosmological distance scale by applying the…
Phase resolved spectroscopy and Kepler photometry of the ultracompact AM CVn binary SDSS J190817.07+394036.4
T. Kupfer, P. J. Groot, S. Bloemen +8
{\it Kepler} satellite photometry and phase-resolved spectroscopy of the ultracompact AM CVn type binary SDSS J190817.07+394036.4 are presented. The average spectra reveal a variet…
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)…
A new HW Vir binary from the Palomar Transient Factory: PTF1 J072455.75+125300.3 - An eclipsing subdwarf B binary with a M-star companion
M. Schindewolf, D. Levitan, U. Heber +4
We report the discovery of an eclipsing binary -- PTF1 J072456125301-- composed of a subdwarf B (sdB) star () with a faint companion. Subdwarf B stars are core helium…
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…
