The CARMENES search for exoplanets around M dwarfs: Stable radial-velocity variations at the rotation period of AD~Leonis -- A test case study of current limitations to treating stellar activity
D. Kossakowski, M. Kürster, Th. Henning +34
Context: A challenge with radial-velocity (RV) data is disentangling the origin of signals either due to a planetary companion or to stellar activity. In fact, the existence of a p…
A new third planet and the dynamical architecture of the HD33142 planetary system
Trifon Trifonov, Anna Wollbold, Martin Kürster +24
Based on recently-taken and archival HARPS, FEROS and HIRES radial velocities (RVs), we present evidence for a new planet orbiting the first ascent red giant star HD33142 (with an…
The HD 260655 system: Two rocky worlds transiting a bright M dwarf at 10 pc
R. Luque, B. J. Fulton, M. Kunimoto +64
We report the discovery of a multi-planetary system transiting the M0 V dwarf HD 260655 (GJ 239, TOI-4599). The system consists of at least two transiting planets, namely HD 260655…
Dynamical architecture of the HD 107148 system
Jan Eberhardt, Trifon Trifonov, Martin Kürster +15
We present an independent Doppler validation and dynamical orbital analysis of the two-planet system HD 107148, which was recently announced in Rosenthal et al. (2021). Our detaile…
A transiting, temperate mini-Neptune orbiting the M dwarf TOI-1759 unveiled by TESS
Néstor Espinoza, Enric Pallé, Jonas Kemmer +66
We report the discovery and characterization of TOI-1759~b, a temperate (400 K) sub-Neptune-sized exoplanet orbiting the M~dwarf TOI-1759 (TIC 408636441). TOI-1759 b was observed b…
Discovery and mass measurement of the hot, transiting, Earth-sized planet GJ 3929 b
J. Kemmer, S. Dreizler, D. Kossakowski +64
We report the discovery of GJ 3929 b, a hot Earth-sized planet orbiting the nearby M3.5 V dwarf star, GJ 3929 (G 180--18, TOI-2013). Joint modelling of photometric observations fro…
