RedDots: Multiplanet system around M dwarf GJ 887 in the solar neighborhood
C. Hartogh, S. V. Jeffers, S. Dreizler +7
GJ 887 is a bright M dwarf in the solar neighborhood with two currently reported nontransiting exoplanets with periods of and along with an addition…
The CARMENES search for exoplanets around M dwarfs : Understanding the wavelength dependence of radial velocity measurements
S. V. Jeffers, J. R. Barnes, P. Schöfer +22
Context. Current exoplanet surveys are focused on detecting small exoplanets orbiting in the liquid-water habitable zones of their host stars. Despite the recent significant advanc…
RedDots: Planetary masses in the GJ1061 system from planet-planet interaction
S. Dreizler, S. V. Jeffers, F. Liebing +8
GJ1061 is a very nearby M star hosting three low-mass temperate planets detected from radial velocity variations. The close to 4:2:1 period commensurability of the planets, the ava…
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…
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 (…
