TOI 564 b and TOI 905 b: Grazing and Fully Transiting Hot Jupiters Discovered by TESS
Allen B. Davis, Songhu Wang, Matias Jones +46
We report the discovery and confirmation of two new hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS): TOI 564 b and TOI 905 b. The transits of these two…
Radial-velocity jitter of stars as a function of observational timescale and stellar age
Stefan S. Brems, Martin Kürster, Trifon Trifonov +2
Stars show various amounts of radial velocity (RV) jitter due to varying stellar activity levels. The typical amount of RV jitter as a function of stellar age and observational tim…
TOI-677 b: A Warm Jupiter (P=11.2d) on an eccentric orbit transiting a late F-type star
Andrés Jordán, Rafael Brahm, Néstor Espinoza +46
We report the discovery of TOI-677 b, first identified as a candidate in light curves obtained within Sectors 9 and 10 of the Transiting Exoplanet Survey Satellite (TESS) mission a…
Precise radial velocities of giant stars XIII. A second Jupiter orbiting in 4:3 resonance in the 7 CMa system
R. Luque, T. Trifonov, S. Reffert +8
We report the discovery of a second planet orbiting the K giant star 7 CMa based on 166 high-precision radial velocities obtained with Lick, HARPS, UCLES and SONG. The periodogram…
A giant exoplanet orbiting a very low-mass star challenges planet formation models
J. C. Morales, A. J. Mustill, I. Ribas +179
Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…
The CARMENES search for exoplanets around M dwarfs. Two temperate Earth-mass planet candidates around Teegarden's Star
M. Zechmeister, S. Dreizler, I. Ribas +182
Context. Teegarden's Star is the brightest and one of the nearest ultra-cool dwarfs in the solar neighbourhood. For its late spectral type (M7.0V), the star shows relatively little…
Variables in the Southern Polar Region Evryscope 2016 Dataset
Jeffrey K. Ratzloff, Henry T. Corbett, Nicholas M. Law +6
The regions around the celestial poles offer the ability to find and characterize long-term variables from ground-based observatories. We used multi-year Evryscope data to search f…
Precise radial velocities of giant stars. XI. Two brown dwarfs in 6:1 mean motion resonance around the K giant star Ophiuchi
Andreas Quirrenbach, Trifon Trifonov, Man Hoi Lee +1
We present radial-velocity (RV) measurements for the K giant Oph (= HIP88048, HD163917, HR6698), which reveal two brown dwarf companions with a period ratio close to 6:1. For o…
Precise radial velocities of giant stars. XII. Evidence against the proposed planet Aldebaran b
Katja Reichert, Sabine Reffert, Stephan Stock +2
Radial-velocity variations of the K giant star Aldebaran ( Tau) were first reported in the early 1990s. After subsequent analyses, the radial-velocity variability with a period…
K2-290: a warm Jupiter and a mini-Neptune in a triple-star system
M. Hjorth, A. B. Justesen, T. Hirano +41
We report the discovery of two transiting planets orbiting K2-290 (EPIC 249624646), a bright (V=11.11) late F-type star residing in a triple-star system. It was observed during Cam…
Two Jovian planets around the giant star HD202696. A growing population of packed massive planetary pairs around massive stars?
Trifon Trifonov, Stephan Stock, Thomas Henning +6
We present evidence for a new two-planet system around the giant star HD202696 (= HIP105056, BD+26 4118). The discovery is based on public HIRES radial velocity measurements taken…
