Herschel Observations of Disks around Late-type Stars
Gizis, John E.; Plavchan, Peter; Matrá, Luca +9 more
A set of twenty late-type (K5-M5) stars were observed with the Herschel Space Observatory at 100 and 160 microns with the goal of searching for far-infrared excesses indicative of the presence of circumstellar disks. Out of this sample, four stars (TYC 7443-1102-1, TYC 9340-437-1, GJ 784 and GJ 707) have infrared excesses above their stellar photo…
The Faint Optical Counterparts Catalog at 19.4 < r < 22 mag from Herschel-ATLAS SDP Field
Wu, Hong; Zhu, Yi-Nan; Zhou, Zhi-Min +2 more
We carry out a spectroscopic survey with Hectospec mounted on the 6.5 m Multiple Mirror Telescope to obtain redshifts of optical counterparts of the Herschel-ATLAS sources in the science demonstration phase field. Our work concerns counterparts with a magnitude range at $19.4\lt {r}_{\mathrm{SDSS}}\lt 22$ mag. The observation covers two $\sim 1\ {…
