Planets occur most frequently around cool dwarfs, but only a handful of specific examples are known to orbit the latest-type M stars. Using TESS photometry, we report the discovery of two planets transiting the low-mass star called LP 791-18 (identified by TESS as TOI 736). This star has spectral type M6V, effective temperature 2960 K, and radius 0

Aims: One of the main scientific drivers for ESPRESSO, Échelle SPectrograph, is the detection and characterization of Earth-class exoplanets. With this goal in mind, the ESPRESSO guaranteed time observations (GTO) Catalog identifies the best target stars for a blind search for the radial velocity (RV) signals caused by Earth-class exoplanets

We present preliminary results of a photometric program aimed to study the rotational properties of the population of Mars-crosser asteroids by means of CCD photometry. We use a set of small robotic telescopes located in the Teide Observatory (Tenerife, Spain) and the Isaac Aznar Observatory (Alcublas, Spain). A total of 54 Mars Crossers were

Saturn's atmosphere is characterised by a thick yellow haze that envelopes its entire surface. What causes this haze to be yellow, however, remains unknown. We argue in this talk that the yellow haze colour could be a result of two or more colour production processes.

Growing evidence in recent years suggests a systematic variation of the stellar initial mass function (IMF), being top-heavy for starburst galaxies and possibly bottom-heavy for massive ellipticals. Galaxy chemical evolution simulations adopting an invariant canonical IMF face difficulty in simultaneously reproducing the metallicity and α

The Low-Frequency Array radio telescope discovered the 707 Hz binary millisecond pulsar (MSP) J0952-0607 in a targeted radio pulsation search of an unidentified Fermi gamma-ray source. This source shows a weak energy flux of F γ = 2.6 × 10 -12 erg cm -2 s -1 in the energy range between 100 MeV and 100 GeV. Here we report the detection of pulsed
