  • M dwarf stars rotational broadening measurements

    Main-sequence, fully convective M dwarfs in eclipsing binaries are observed to be larger than stellar evolutionary models predict by as much as 10%-15%. A proposed explanation...
  • Late-Type Extension to MoVeRS (LaTE-MoVeRS)

    We present the Late-Type Extension to the Motion Verified Red Stars (LaTE-MoVeRS) catalog, containing 46,463 photometric late-type (>M5) dwarfs within the Sloan Digital Sky...
  • Motion Verified Red Stars (MoVeRS)

    We present a photometric catalog of 8,735,004 proper motion selected low-mass stars (KML-spectral types) within the Sloan Digital Sky Survey (SDSS) footprint, from the combined...
  • Photometry and spectroscopy of HATS-6

    We report the discovery by the HATSouth survey of HATS-6b, an extrasolar planet transiting a V=15.2mag, i=13.7mag M1V star with a mass of 0.57M_{Sun} and a radius of 0.57R{sun}...
  • Flares and rotation of M dwarfs

    More than 4000 exoplanets have been discovered to date, providing the search for a place capable of hosting life with a large number of targets. With the Transiting Exoplanet...
  • First eROSITA study of nearby M dwarfs

    We present the first results with the ROentgen Survey with an Imaging Telescope Array (eROSITA) on board the Russian Spektrum-Roentgen-Gamma mission (SRG), and we combine the...
  • CARMENES input catalogue of M dwarfs. V.

    The relevance of M dwarfs in the search for potentially habitable Earth-size planets has grown significantly in the last years. In our on-going effort of comprehensively and...
  • Spectro-interferometric observation of SW Vir

    We present a near-infrared spectro-interferometric observation of the non-Mira-type, semiregular asymptotic giant branch star SW Vir. Our aim is to probe the physical properties...
  • HARPS XXXI. The M-dwarf sample

    Searching for planets around stars with different masses helps us to assess the outcome of planetary formation for different initial conditions. The low-mass M dwarfs are also...
  • Emission lines in a giant flare of CN Leo

    Flares on dM stars contain plasmas at very different temperatures and thus affect a wide wavelength range in the electromagnetic spectrum. While the coronal properties of flares...
  • Globular clusters luminosity function

    Data of figure 1 of the paper, namely the luminosity function of globular clusters in bolometric magnitude. The original HST magnitude is given, then the corresponding...
  • Palomar/MSU nearby star spectroscopic survey

    The Third Catalogue of Nearby Stars (Gliese & Jahreiss, "Preliminary Version of the third Catalogue of Nearby Stars" (CNS3), 1991, catalog ) includes over 1850 stars which...
  • CARMENES M dwarf template library

    Light from celestial objects interacts with the molecules of the Earth's atmosphere, resulting in the production of telluric absorption lines in ground-based spectral data....
  • TESS monitoring campaign of low-mass flare stars

    A 20s cadence Transiting Exoplanet Survey Satellite monitoring campaign of 226 low-mass flare stars during Cycle 3 recorded 3792 stellar flares of >=10^32^erg. We explore the...
  • GJ 724 and GJ 3988 RV timeseries

    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 3.5m Calar Alto/CARMENES...
  • Solar neighborhood. XXXV. Distances to M dwarfs

    We present trigonometric, photometric, and photographic distances to 1748 southern ({delta}{<=}O{deg}) M dwarf systems with {mu}>=0.18''/yr, of which 1404 are believed to...
  • Photospheric parameters of CARMENES stars

    The new CARMENES instrument comprises two high-resolution and high-stability spectrographs that are used to search for habitable planets around M dwarfs in the visible and...
  • Spectral analysis of 636 SDSS WD-M binaries

    We present a catalog of 857 WD-M star binaries from the Sloan Digital Sky Survey (SDSS), most of which were previously identified by other authors, and the results of our...
