Occurrence rates of small planets from HARPS: Focus on the Galactic context

Dolev Bashi, Shay Zucker, Vardan Adibekyan +4

Context. The stars in the Milky Way thin and thick disks can be distinguished by several properties such as metallicity and kinematics. It is not clear whether the two populations…

The CARMENES search for exoplanets around M dwarfs. Three temperate to warm super-Earths

S. Stock, E. Nagel, J. Kemmer +37

We announce the discovery of two planets orbiting the M dwarfs GJ 251 ( M) and HD 238090 ( M) based on CARMENES radial velocity (RV) d…

Maintaining the Ephemeris of 20 CoRoT Planets: Transit Minimum Times and Potential Transit Timing Variations

Hans J. Deeg, Peter Klagyivik, J. D. Armstrong +11

We present 33 transit minimum times of 20 transiting planets discovered by the CoRoT mission, which have been obtained from ground-based observations since the mission's end in 201…

Discriminating between hazy and clear hot-Jupiter atmospheres with CARMENES

A. Sánchez-López, M. López-Puertas, I. A. G. Snellen +20

Context: Relatively large radii of some hot Jupiters observed in the ultraviolet (UV) and blue-optical are generally interpreted to be due to Rayleigh scattering by high-altitude h…

Precise mass and radius of a transiting super-Earth planet orbiting the M dwarf TOI-1235: a planet in the radius gap?

P. Bluhm, R. Luque, N. Espinoza +78

We report the confirmation of a transiting planet around the bright, inactive M0.5 V star TOI-1235 (TYC 4384-1735-1, V = 11.5 mag), whose transit signal was detected in the photome…

The CARMENES search for exoplanets around M dwarfs. A super-Earth planet orbiting HD 79211 (GJ 338 B)

E. González-Álvarez, M. R. Zapatero Osorio, J. A. Caballero +27

We report on radial velocity time series for two M0.0V stars, GJ338B and GJ338A, using the CARMENES spectrograph, complemented by ground-telescope photometry from Las Cumbres and S…

A public HARPS radial velocity database corrected for systematic errors

Trifon Trifonov, Lev Tal-Or, Mathias Zechmeister +3

Context. The HARPS spectrograph provides state-of-the-art stellar radial velocity (RV) measurements with a precision down to 1 m/s. The spectra are extracted with a dedicated data-…
