Planetary system around the nearby M dwarf GJ 357 including a transiting, hot, Earth-sized planet optimal for atmospheric characterization

Description: We report the detection of a transiting Earth-size planet around GJ 357, a nearby M2.5 V star, using data from the Transiting Exoplanet Survey Satellite (TESS). GJ 357 b (TOI-562.01) is a transiting, hot, Earth-sized planet (T_(eq) = 525 ± 11 K) with a radius of R_(b) = 1.217 ± 0.084 Rꚛ and an orbit...

The CARMENES search for exoplanets around M dwarfs Detection of a mini-Neptune around LSPM J2116+0234 and refinement of orbital parameters of a super-Earth around GJ 686 (BD+18 3421)

Description: Although M dwarfs are known for high levels of stellar activity, they are ideal targets for the search of low-mass exoplanets with the radial velocity (RV) method. We report the discovery of a planetary-mass companion around LSPM J2116+0234 (M3.0 V) and confirm the existence of a planet orbiting GJ ...

Detection of He I λ10830 Å absorption on HD 189733 b with CARMENES high-resolution transmission spectroscopy

Description: We present three transit observations of HD 189733 b obtained with the high-resolution spectrograph CARMENES at Calar Alto. A strong absorption signal is detected in the near-infrared He I triplet at 10830 Å in all three transits. During mid-transit, the mean absorption level is 0.88 ± 0.04% measure...

Stars and brown dwarfs in the σ Orionis cluster (Research Note) III. OSIRIS/GTC low-resolution spectroscopy of variable sources

Description: Context. Although many studies have been performed so far, there are still dozens of low-mass stars and brown dwarfs in the young σ Orionis open cluster without detailed spectroscopic characterisation. Aims. We look for unknown strong accretors and disc hosts that were undetected in previous surveys...

Comunicación corta: efecto del trampeo masivo tipo OLIPE sobre los artrópodos no objetivo del olivar

Description: Due to the widespread of mass-trapping systems for Bactrocera oleae (Gmelin) (Diptera: Tephritidae) control in organic olive cropping, an assessment of the impact on arthropods of the olive agroecosystem was undertaken for the OLIPE trap type. The sampling was carried out in "Los Pedroches" valley (...
