Starspot distributions on fully convective M dwarfs : implications for radial velocity planet searches
Since M4.5–M9 dwarfs exhibit equatorial rotation velocities of the order of 10 km s −1 on average, radial velocity surveys targeting this stellar population will likely need to find methods to
Analysis of combined radial velocities and activity of BD+20 1790: evidence supporting the existence of a planetary companion
Context. In a previous paper we reported a planetary companion to the young and very active K5Ve star BD+20 1790. We found that this star has a high level of stellar activity (log R'_HK = -3.7) that
Radial velocity studies of cool stars
TLDR
It is found that the mass of M dwarf planets is relatively much lower than the expected mass dependency based on stellar mass and thus it is inferred that planet formation efficiency around low-mass stars is relatively impaired.
CARMENES input catalogue of M dwarfs
CARMENES is a spectrograph for radial velocity surveys of M dwarfs with the aim of detecting Earth-mass planets orbiting in the habitable zones of their host stars. To ensure an optimal use of the
BANYAN. IV. Fundamental parameters of low-mass star candidates in nearby young stellar kinematic groups - Isochronal Age determination using Magnetic evolutionary models
Based on high resolution optical spectra obtained with ESPaDOnS at CFHT, we determine fundamental parameters (\Teff, R, \Lbol, \logg\ and metallicity) for 59 candidate members of nearby young kinem
A 3D Search for Companions to 12 Nearby M-Dwarfs
We present a carefully vetted equatorial ($\pm$ 30$^\circ$ Decl.) sample of all known single (within 4'') mid M-dwarfs (M2.5V-M8.0V) extending out to 10 pc; their proximity and low masses make them
The CARMENES search for exoplanets around M dwarfs
Context. Previous simulations predicted the activity-induced radial-velocity (RV) variations of M dwarfs to range from ~1 cm s−1 to ~1 km s−1, depending on various stellar and activity parameters.
Modeling the RV jitter of early M dwarfs using tomographic imaging
In this paper we show how tomographic imaging (Zeeman Doppler Imaging, ZDI) can be used to characterize stellar activity and magnetic field topologies, ultimately allowing to filter out the radial
The red dwarf pair GJ65 AB: inflated, spinning twins of Proxima - Fundamental parameters from PIONIER, NACO, and UVES observations
The nearby red dwarf binary GJ65 AB (UV+BL Ceti, M5.5Ve+M6Ve) is a cornerstone system to probe the physics of very low-mass stars. The radii of the two stars are currently known only from indirect
