HD 191939 revisited: New and refined planet mass determinations, and a new planet in the habitable zone
J. Orell-Miquel, G. Nowak, F. Murgas +20
HD 191939 (TOI-1339) is a nearby (d=54pc), bright (V=9mag), and inactive Sun-like star (G9 V) known to host a multi-planet transiting system. Ground-based spectroscopic observation…
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…
Precise mass determination for the keystone sub-Neptune planet transiting the mid-type M dwarf G 9-40
R. Luque, G. Nowak, T. Hirano +45
Context. Despite being a prominent subset of the exoplanet population discovered in the past three decades, the nature and provenance of sub-Neptune-sized planets are still one of…
The Hot Neptune WASP-166~b with ESPRESSO I: Refining the Planetary Architecture and Stellar Variability
L. Doyle, H. M. Cegla, E. Bryant +24
In this paper, we present high-resolution spectroscopic transit observations from ESPRESSO of the super-Neptune WASP-166~b. In addition to spectroscopic ESPRESSO data, we analyse p…
The CARMENES search for exoplanets around M dwarfs. Rotational variation in activity indicators of Ross 318, YZ CMi, TYC 3529-1437-1, and EV Lac
P. Schöfer, S. V. Jeffers, A. Reiners +22
The CARMENES instrument is searching for periodic radial-velocity (RV) variations of M dwarfs, which are induced by orbiting planets. However, there are other potential sources of…
The Hot Neptune WASP-166 b with ESPRESSO II: Confirmation of atmospheric sodium
J. V. Seidel, H. M. Cegla, L. Doyle +8
The hot Neptune desert, a distinct lack of highly irradiated planets in the size range of Neptune, remains one of the most intriguing results of exoplanet population studies. A dee…
