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…
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…
RedDots: Limits on habitable and undetected planets orbiting nearby stars GJ 832, GJ 674, and Ross 128
F. Liebing, S. V. Jeffers, P. Gorrini +16
Aims. Using HARPS spectroscopic data obtained by the RedDots campaign, as well as archival data from HARPS and CARMENES, supplemented with ASH2 and T90 photometry, we aim to search…
Planetary companions orbiting the M dwarfs GJ 724 and GJ 3988. A CARMENES and IRD collaboration
P. Gorrini, J. Kemmer, S. Dreizler +36
We report the discovery of two exoplanets around the M dwarfs GJ 724 and GJ 3988 using the radial velocity (RV) method. We obtained a total of 153 3.5 m Calar Alto/CARMENES spectra…
Detailed stellar activity analysis and modelling of GJ 832: Reassessment of the putative habitable zone planet GJ 832c
P. Gorrini, N. Astudillo-Defru, S. Dreizler +27
Context. Gliese 832 (GJ 832) is an M2V star hosting a massive planet on a decade-long orbit, GJ 832b, discovered by radial velocity (RV). Later, a super Earth or mini-Neptune orbit…
The HD 260655 system: Two rocky worlds transiting a bright M dwarf at 10 pc
R. Luque, B. J. Fulton, M. Kunimoto +64
We report the discovery of a multi-planetary system transiting the M0 V dwarf HD 260655 (GJ 239, TOI-4599). The system consists of at least two transiting planets, namely HD 260655…
