The CARMENES search for exoplanets around M dwarfs -- LP 714-47b (TOI 442.01): Populating the Neptune desert

S. Dreizler, I., J. +134

We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, m_b = 30.8 +/- 1.5 M_earth , R_b = 4.7 +/- 0.3 R_earth ) located in the 'hot Neptune desert'. Confirma…

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…

The widest broadband transmission spectrum (0.38-1.71 m) of HD 189733b from ground-based chromatic Rossiter-McLaughlin observations

M. Oshagh, F. F. Bauer, M. Lafarga +22

Multiband photometric transit observations (spectro-photometric) have been used mostly so far to retrieve broadband transmission spectra of transiting exoplanets in order to study…

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…

The CARMENES search for exoplanets around M dwarfs -- A deep learning approach to determine fundamental parameters of target stars

V. M. Passegger, A. Bello-García, J. Ordieres-Meré +26

Existing and upcoming instrumentation is collecting large amounts of astrophysical data, which require efficient and fast analysis techniques. We present a deep neural network arch…

The CARMENES search for exoplanets around M dwarfs: Convective shift and starspot constraints from chromatic radial velocities

D. Baroch, J. C. Morales, I. Ribas +26

Context. Variability caused by stellar activity represents a challenge to the discovery and characterization of terrestrial exoplanets and complicates the interpretation of atmosph…
