Companions to Kepler giant stars: A long-period eccentric substellar companion to KIC 3526061 and a stellar companion to HD 187878
Marie Karjalainen, Raine Karjalainen, Artie P. Hatzes +12
Context. Our knowledge of populations and occurrence of planets orbiting evolved intermediate-mass stars is still incomplete. In 2010 we started a planet-search program among 95 gi…
TOI-1670 b and c: An Inner Sub-Neptune with an Outer Warm Jupiter Unlikely to have Originated from High-Eccentricity Migration
Quang H. Tran, Brendan P. Bowler, Michael Endl +38
We report the discovery of two transiting planets around the bright ( mag) main sequence F7 star TOI-1670 by the Transiting Exoplanet Survey Satellite. TOI-1670 b is a sub-N…
A Near-Infrared Chemical Inventory of the Atmosphere of 55 Cancri e
Emily K. Deibert, Ernst J. W. de Mooij, Ray Jayawardhana +4
We present high-resolution near-infrared spectra taken during eight transits of 55 Cancri e, a nearby low-density super-Earth with a short orbital period (< 18 hours). While this e…
Detection of ionized calcium in the atmosphere of the ultra-hot Jupiter KELT-9b
Jake D. Turner, Ernst J. W. de Mooij, Ray Jayawardhana +6
With a day-side temperature in excess of 4500K, comparable to a mid-K-type star, KELT-9b is the hottest planet known. Its extreme temperature makes KELT-9b a particularly interesti…
Time resolved spectroscopy of dust and gas from extrasolar planetesimals orbiting WD 1145+017
Marie Karjalainen, Ernst J. W. de Mooij, Raine Karjalainen +1
Multiple long and variable transits caused by dust from possibly disintegrating asteroids were detected in light curves of WD 1145+017. We present time-resolved spectroscopic obser…
Authenticating the Presence of a Relativistic Massive Black Hole Binary in OJ 287 Using its General Relativity Centenary Flare: Improved Orbital Parameters
Lankeswar Dey, M. J. Valtonen, A. Gopakumar +5
Results from regular monitoring of relativistic compact binaries like PSR 1913+16 are consistent with the dominant (quadrupole) order emission of gravitational waves (GWs). We show…
