Mitigating stellar radial velocity jitter using orthogonal activity indices and a time-aware neural network
Jordi Blanco-Pozo, Manuel Perger, Guillem Anglada-Escudé +7
Despite recent advances in the precision of high-resolution spectrographs, the detection of Earth-like exoplanets is still limited by the effects of stellar activity, which introdu…

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…

HADES RV Programme with HARPS-N at TNG. XVI. A super-Earth in the habitable zone of the GJ 3998 multi-planet system
A. K. Stefanov, A. Suárez Mascareño, J. I. González Hernández +12
The low masses of M dwarfs create attractive opportunities for exoplanet radial-velocity (RV) detections. These stars, however, exhibit strong stellar activity that may attenuate o…
