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)…
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…
VI-Band Follow-Up Observations of Ultra-Long-Period Cepheid Candidates in M31
Chow-Choong Ngeow, Chien-Hsiu Lee, Michael Ting-Chang Yang +7
The ultra-long period Cepheids (ULPCs) are classical Cepheids with pulsation periods exceeding days. The intrinsic brightness of ULPCs are ~1 to ~3 mag brighter than t…
