The Rapid X-ray and UV Evolution of ASASSN-14ko
Anna V. Payne, Benjamin J. Shappee, Jason T. Hinkle +13
ASASSN-14ko is a recently discovered periodically flaring transient at the center of the AGN ESO 253-G003 with a slowly decreasing period. Here we show that the flares originate fr…
TIC 168789840: A Sextuply-Eclipsing Sextuple Star System
Brian P. Powell, Veselin B. Kostov, Saul A. Rappaport +48
We report the discovery of a sextuply-eclipsing sextuple star system from TESS data, TIC 168789840, also known as TYC 7037-89-1, the first known sextuple system consisting of three…
Maintaining the Ephemeris of 20 CoRoT Planets: Transit Minimum Times and Potential Transit Timing Variations
Hans J. Deeg, Peter Klagyivik, J. D. Armstrong +11
We present 33 transit minimum times of 20 transiting planets discovered by the CoRoT mission, which have been obtained from ground-based observations since the mission's end in 201…
ASASSN-14ko is a Periodic Nuclear Transient in ESO 253-G003
Anna V. Payne, Benjamin J. Shappee, Jason T. Hinkle +24
We present the discovery that ASASSN-14ko is a periodically flaring AGN at the center of the galaxy ESO 253-G003. At the time of its discovery by the All-Sky Automated Survey for S…
GJ 1252 b: A 1.2 planet transiting an M3-dwarf at 20.4 pc
Avi Shporer, Karen A. Collins, Nicola Astudillo-Defru +35
We report the discovery of GJ 1252 b, a planet with a radius of 1.193 0.074 and an orbital period of 0.52 days around an M3-type star (0.381 0.019 $M_{\odo…
Photometry and spectroscopy of massive stars observed during K2 Campaign 8
Jéssica M. Eidam, Laerte Andrade, Marcelo Emilio +4
We report in this paper spectroscopic and photometric analysis of eight massive stars observed during Campaign 8 of the Kepler/K2 mission from January to March 2016. Spectroscopic…
