Palomar Transient Factory and RR Lyrae: Metallicity-Light Curve Relation Based on ab-Type RR Lyrae in Kepler Field
Chow-Choong Ngeow, Po-Chieh Yu, Eric Bellm +6
The wide-field synoptic sky surveys, known as the Palomar Transient Factory (PTF) and the intermediate Palomar Transient Factory (iPTF), will accumulate a large number of known and…
LAMOST Observations of Flaring M Dwarfs in the Kepler Field
H. -Y. Chang, Y. -H. Song, A. -L. Luo +7
A sample of the LAMOST spectra of the early type M0-M3 dwarfs is compared with the Kepler observations. It is found that M dwarfs with strong chromospheric emission in have l…
Evolution of CO, CH, and OCS abundances relative to HO in the coma of comet 67P around perihelion from Rosetta/VIRTIS-H observations
D. Bockelée-Morvan, J. Crovisier, S. Erard +19
Infrared observations of the coma of 67P/Churyumov-Gerasimenko were carried out from July to September 2015, i.e., around perihelion (13 August 2015), with the high-resolution chan…
The Pan-STARRS 1 Discoveries of five new Neptune Trojans
Hsing Wen Lin, Ying-Tung Chen, Matthew J. Holman +16
In this work we report the detection of seven Neptune Trojans (NTs) in the Pan-STARRS 1 (PS1) survey. Five of these are new discoveries, consisting of four L4 Trojans and one L5 Tr…
Sublimation of icy aggregates in the coma of comet 67P/Churyumov-Gerasimenko detected with the OSIRIS cameras onboard Rosetta
A. Gicquel, J. -B. Vincent, J. Agarwal +58
Beginning in March 2014, the OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) cameras began capturing images of the nucleus and coma (gas and dust) of comet 67P/…
Large Super-Fast Rotator Hunting Using the Intermediate Palomar Transient Factory
Chan-Kao Chang, Hsing-Wen Lin, Wing-Huen Ip +5
In order to look for large super-fast rotators, five dedicated surveys covering ~ 188 square degree in the ecliptic plane have been carried out in R-band with ~10 min cadence using…
