HATS-71b: A giant planet transiting an M3 dwarf star in TESS Sector 1
G. Á. Bakos, D. Bayliss, J. Bento +41
We report the discovery of HATS-71b, a transiting gas giant planet on a P = 3.7955 day orbit around a G = 15.35 mag M3 dwarf star. HATS-71 is the coolest M dwarf star known to host…
HATS-54b-HATS-58Ab: five new transiting hot Jupiters including one with a possible temperate companion
Néstor Espinoza, Joel D. Hartman, Gaspar Á. Bakos +18
We report the discovery by the HATSouth project of 5 new transiting hot Jupiters (HATS-54b through HATS-58Ab). HATS-54b, HATS-55b and HATS-58Ab are prototypical short period ($P =…
Ultralow-amplitude RR Lyrae Stars in M4
Joshua J. Wallace, Joel D. Hartman, Gaspar A. Bakos +1
We report evidence for a new class of variable star, which we dub millimagnitude RR Lyrae (mmRR). From K2 observations of the globular cluster M4, we find that out of 24 horizontal…
HATS-70b: A 13 Mjup brown dwarf transiting an A star
G. Zhou, G. Á. Bakos, D. Bayliss +23
We report the discovery of HATS-70b, a transiting brown dwarf at the deuterium burning limit. HATS-70b has a mass of Mp=12.9 +1.8/-1.6 Mjup and a radius of Rp=1.384 +0.079/-0.074 R…
Eclipsing Spotted Giant Star With K2 and Historical Photometry
K. Oláh, S. Rappaport, T. Borkovits +15
Context. Stars can maintain their observable magnetic activity from the PMS to the tip of the red giant branch. However, the number of known active giants is much lower than active…
A Discrete Set of Possible Transit Ephemerides for Two Long Period Gas Giants Orbiting HIP 41378
Juliette C. Becker, Andrew Vanderburg, Joseph E. Rodriguez +22
In 2015, K2 observations of the bright (V = 8.9, K = 7.7) star HIP 41378 revealed a rich system of at least five transiting exoplanets, ranging in size from super-Earths to gas gia…
