A team of astronomers from the University of Chile, in collaboration with the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), has discovered the first “ultrahot Neptune”, which is in orbita round the nearby star LTT 9779. The planet is so close to its star that its year lasts only 19 hours, and the star’s radiation heats the planet to more than 1,700 degrees centigrade. At those temperaturas, the heavy elements such as iron can be ionized in the atmosphere and molecules can dissociate, which makes this a unique laboratory for studying the chemistry of

The two near-Earth asteroids Ryugu and Bennu, primary targets of the Hayabusa2 (JAXA) and OSIRIS-REx (NASA) space missions, keep surprising us. In two companion papers presented in Nature Astronomy, researchers have found exogenous bright material scattered across the asteroids’ surfaces. Members of the Solar System Group of the Instituto de Astrofísica de Canarias (IAC) have contributed to this discovery, in particular Dr. Eri Tatsumi, who is the first author of the paper presenting findings on Ryugu (Hayabusa2).

With data from NASA’s TESS satellite, from the now retired Spitzer Space Telescope, and the Gran Telescopio Canarias (GTC) an international team of astronomers, with participation from the Instituto de Astrofísica de Canarias (IAC) has detected what appears to be an intact planet in orbit around a white dwarf, the dense remains of a star similar to the Sun , and only 40 % bigger in diameter than the Earth. This finding is published today in Nature magazine.

The journal Nature Communications today is publishing the discovery of a new type of stars, very rich in phosphorus, which could help to explain the origin of this chemical element in our Galaxy. This achievement has been made by astronomers of the Instituto de Astrofísica de Canarias (IAC) and researchers in computer science from the Centre for Research in Information and Communication Technology (CITIC) at the University of La Coruña (Galicia).

A study led by researchers at the Instituto de Astrofísica de Canarias (IAC), making comparison between the discs of several pairs of spiral galaxies, active and non-active, concludes that in the discs of the former the rotational motion of the stars is of greater importance. This study, just accepted for publication in Astronomy & Astrophysics Letters, is the first evidence for large scale dynamical differences between active and non-active galaxies in the local universe. The astronomers participating are from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna
