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…
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…
RV-exoplanet eccentricities: Good, Beta, and Best
A. T. Stevenson, C. A. Haswell, J. P. Faria +4
We examine the eccentricity distribution(s) of radial velocity detected exoplanets. Previously, the eccentricity distribution was found to be described well by a Beta distribution…
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…
The variable magnetic field of V889 Her and the challenge of detecting exoplanets around young Suns using Gaussian process regression
E. L. Brown, S. C. Marsden, S. V. Jeffers +3
Discovering exoplanets orbiting young Suns can provide insight into the formation and early evolution of our own solar system, but the extreme magnetic activity of young stars obfu…
