Dynamical analysis of the 5:1 mean-motion resonance of the HD 202206 system
Yingyi Cao, Man Hoi Lee, Sabine Reffert +2
The HD 202206 system, which features two substellar companions with a 5:1 period ratio around a solar-type star, offers a rare opportunity to study high-order mean-motion resonance…
Tighter constraints on the atmosphere of GJ 436 b from combined high-resolution CARMENES and CRIRES observations
A. Peláez-Torres, A. Sánchez-López, L. Nortmann +23
We aim to study the atmospheric properties of the warm Neptune GJ 436 b by combining a set of five transit events observed with the CARMENES spectrograph with one transit from CRIR…
The mass of the exo-Venus Gliese 12 b, as revealed by HARPS-N, ESPRESSO, and CARMENES
Daisy A. Turner, Yoshi Nike Emilia Eschen, Felipe Murgas +60
Small temperate planets are prime targets for exoplanet studies due to their possible similarities with the rocky planets in the Solar System. M dwarfs are promising hosts since th…
Discovery of a transiting hot water-world candidate orbiting Ross 176 with TESS and CARMENES
S. GeraldÃa-González, J. Orell-Miquel, E. Pallé +30
The case of Ross 176 is a late K-type star that hosts a promising water-world candidate planet. The star has a radius of =0.5690.020 and a mass of …
The CARMENES search for exoplanets around M dwarfs. Revisiting the GJ 317, GJ 463, and GJ 3512 systems and two newly discovered planets orbiting GJ 9773 and GJ 508.2
J. C. Morales, I. Ribas, S. Reffert +33
Surveys for exoplanets indicate that the occurrence rate of gas giant planets orbiting late-type stars in orbits with periods shorter than 1000 days is lower than in the case of Su…
Precise radial velocities of giant stars -- XVII. Distinguishing planets from intrinsically induced radial velocity signals in evolved stars
Dane Spaeth, Sabine Reffert, Trifon Trifonov +6
From a long-term Doppler monitoring campaign of 373 giant stars, we have identified ten giants with periodic radial velocity variations that are challenging to associate with plane…
