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…
TESS Asteroseismology of the known red-giant host stars HD 212771 and HD 203949
Tiago L. Campante, Enrico Corsaro, Mikkel N. Lund +45
The Transiting Exoplanet Survey Satellite (TESS) is performing a near all-sky survey for planets that transit bright stars. In addition, its excellent photometric precision enables…
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…
Planetary system around the nearby M dwarf GJ 357 including a transiting, hot, Earth-sized planet optimal for atmospheric characterization
R. Luque, E. Pallé, D. Kossakowski +73
We report the detection of a transiting Earth-size planet around GJ 357, a nearby M2.5V star, using data from the Transiting Exoplanet Survey Satellite (TESS). GJ 357 b (TOI-562.01…
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…
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…
