Absolute dimensions of the eccentric eclipsing binary V541 Cygni
G. Torres, C. D. McGruder, R. J. Siverd +6
We report new spectroscopic and photometric observations of the main-sequence, detached, eccentric, double-lined eclipsing binary V541 Cyg (P = 15.34 days, e = 0.468). Using these…
V473 Lyr, a modulated, period-doubled Cepheid, and U TrA, a double-mode Cepheid observed by MOST
L. Molnár, A. Derekas, R. Szabó +36
Space-based photometric measurements first revealed low-amplitude irregularities in the pulsations of Cepheid stars, but their origins and how commonly they occur remain uncertain.…
A Type II Supernova Hubble diagram from the CSP-I, SDSS-II, and SNLS surveys
T. de Jaeger, S. González-Gaitán, M. Hamuy +15
The coming era of large photometric wide-field surveys will increase the detection rate of supernovae by orders of magnitude. Such numbers will restrict spectroscopic follow-up in…
Faint source star planetary microlensing: the discovery of the cold gas giant planet OGLE-2014-BLG-0676Lb
N. J. Rattenbury, D. P. Bennett, T. Sumi +85
We report the discovery of a planet --- OGLE-2014-BLG-0676Lb --- via gravitational microlensing. Observations for the lensing event were made by the MOA, OGLE, Wise, RoboNET/LCOGT,…
Determining Empirical Stellar Masses and Radii Using Transits and Gaia Parallaxes as Illustrated by Spitzer Observations of KELT-11b
Thomas G. Beatty, Daniel J. Stevens, Karen A. Collins +8
Using the Spitzer Space Telescope, we observed a transit at 3.6um of KELT-11b (Pepper et al. 2017). We also observed three partial transits from the ground. We simultaneously fit t…
Two New Calcium-Rich Gap Transients in Group and Cluster Environments
R. Lunnan, M. M. Kasliwal, Y. Cao +20
We present the Palomar Transient Factory discoveries and the photometric and spectroscopic observations of PTF11kmb and PTF12bho. We show that both transients have properties consi…
