The CARMENES search for exoplanets around M dwarfs. The impact of rotation and magnetic fields on the radial velocity jitter in cool stars

H. L. Ruh, M. Zechmeister, A. Reiners +19

Radial velocity (RV) jitter represents an intrinsic limitation on the precision of Doppler searches for exoplanets that can originate from both instrumental and astrophysical sourc…

CARMENES input catalogue of M dwarfs VIII. Kinematics in the solar neighbourhood

M. Cortés-Contreras, J. A. Caballero, D. Montes +15

Aims. Our goals are to characterise the kinematic properties and to identify young and old stars among the M dwarfs of the CARMENES input catalogue. Methods. We compiled the spectr…

Identifying activity induced RV periodicities and correlations using Central Line Moments

J. R. Barnes, S. V. Jeffers, C. A. Haswell +5

The radial velocity (RV) method of exoplanet detection requires mitigation of nuisance signals arising from stellar activity. Using analytic cool and facular spot models, we explor…

TOI-4438 b: a transiting mini-Neptune amenable to atmospheric characterization

E. Goffo, P. Chaturvedi, F. Murgas +47

We report the confirmation and mass determination of a mini-Neptune transiting the M3.5 V star TOI-4438 (G 182-34) every 7.44 days. A transit signal was detected with NASA's TESS s…

Wolf 327b: A new member of the pack of ultra-short-period super-Earths around M dwarfs

F. Murgas, E. Pallé, J. Orell-Miquel +52

Planets with orbital periods shorter than 1 day are rare and have formation histories that are not completely understood. Small () ultra-short-period (…

CARMENES input catalog of M dwarfs: VII. New rotation periods for the survey stars and their correlations with stellar activity

Yutong Shan, Daniel Revilla, Sebastian L. Skrzypinski +40

Abridged: We measured photometric and spectroscopic for a large sample of nearby bright M dwarfs with spectral types from M0 to M9, as part of our continual effort to…
