The architecture of the hierarchical triple star KOI 928 from eclipse timing variations seen in Kepler photometry
J. H. Steffen, S. N. Quinn, W. J. Borucki +25
We present a hierarchical triple star system (KIC 9140402) where a low mass eclipsing binary orbits a more massive third star. The orbital period of the binary (4.98829 Days) is de…

Long-lived, long-period radial velocity variations in Aldebaran: A planetary companion and stellar activity
A. P. Hatzes, W. D. Cochran, M. Endl +14
We investigate the nature of the long-period radial velocity variations in Alpha Tau first reported over 20 years ago. We analyzed precise stellar radial velocity measurements for…

Searching for the expelled hydrogen envelope in Type I supernovae via late-time H-alpha emission
J. Vinko, D. Pooley, J. M. Silverman +6
We report the first results from our long-term observational survey aimed at discovering late-time interaction between the ejecta of hydrogen-poor Type I supernovae and the hydroge…
