RedDots: Magnetic field of the nearby active M dwarf GJ 729, and a search for companions
E. L. Brown, S. V. Jeffers, S. C. Marsden +5
M dwarfs are prime targets for discovering exoplanets, and the nearest M dwarfs to the Sun provide among the best opportunities for follow-up detailed exoplanet characterization. G…
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…
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…
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…
Convective blueshift strengths for 242 evolved stars
F. Liebing, S. V. Jeffers, M. Zechmeister +1
Context. Extreme precision radial velocity (RV) surveys seeking to detect planets at RV semi-amplitudes of 10 cm/s are facing numerous challenges. One of those challenges is convec…
Convective blueshift strengths of 810 F to M solar-type stars
F. Liebing, S. V. Jeffers, A. Reiners +1
The detection of Earth-mass exoplanets in the habitable zone around solar-mass stars using the radial velocity technique requires extremely high precision, on the order of 10cm…
The quest for companions to post-common envelope binaries. II. NSVS14256825 and HS0705+6700
K. Beuermann, P. Breitenstein, B. Debski +20
We report new mid-eclipse times of the two close binaries NSVS14256825 and HS0705+6700, harboring an sdB primary and a low-mass main-sequence secondary. Both objects display clear…
