Two Kepler red-giant eclipsing binaries as lower red-giant branch benchmarks for asteroseismic scaling relations. Dynamical masses and radii from JKTEBOP and PHOEBE-2 modeling
A. Hedlund, P. Gaulme, J. Jackiewicz +3
Space-based photometry has detected solar-like oscillations in thousands of stars, whose global seismic parameters yield stellar properties via the asteroseismic scaling relations.…
Variable Blue Straggler Stars in Open Cluster NGC 6819 Observed in the Kepler 'Superstamp' Field
Joyce A. Guzik, Andrzej S. Baran, Sachu Sanjayan +4
NGC 6819 is an open cluster of age 2.4 Gyr that was in the NASA Kepler spacecraft field of view from 2009 to 2013. The central part of the cluster was observed in a 200 x 200 pixel…
KIC 7955301: a hierarchical triple system with eclipse timing variations and an oscillating red giant
P. Gaulme, T. Borkovits, T. Appourchaux +13
KIC 7955301 is a hierarchical triple system with eclipse timing and depth variations discovered by the Kepler mission. It is composed of a non-eclipsing primary star at the bottom…
Active red giants: close binaries versus single rapid rotators
Patrick Gaulme, Jason Jackiewicz, Federico Spada +7
The objective of this work is to determine what fraction of red-giant (RG) stars shows photometric rotational modulation, and understand its origin. One of the underlying questions…
Variability in the Massive Open Cluster NGC 1817 from K2: A Rich Population of Asteroseismic Red Clump, Eclipsing Binary, and Main Sequence Pulsating Stars
Eric L. Sandquist, Dennis Stello, Torben Arentoft +13
We present a survey of variable stars detected in K2 Campaign 13 within the massive intermediate age ( Gyr) open cluster NGC 1817. We identify a complete sample of 44 red cl…
Short GRB 130603B: Discovery of a jet break in the optical and radio afterglows, and a mysterious late-time X-ray excess
Wen-fai Fong, Edo Berger, Brian D. Metzger +13
We present radio, optical/NIR, and X-ray observations of the afterglow of the short-duration 130603B, and uncover a break in the radio and optical bands at 0.5 d after the burst, b…
