An international team of researchers with participation of the Institute of Astrophysics of Andalusia (IAA-CSIC) has measured with unprecedented accuracy the mass and the radius of Gliese 486 b, an exoplanet of the “super-Earth” category, discovered in 2021 by the CARMENES instrument at the Calar Alto Observatory. This study allows, for the first time, to make robust predictions on the internal structure and composition of a super-Earth.

An international team of astronomers led by José A. Caballero, from Centre of Astrobiology (CAB) CSIC-INTA in Madrid, with participation of the Institute of Astrophysics of Andalusia (IAA-CSIC) in Granada, has been able to model the interior of the exoplanet Gliese 486 b, and to estimate the relative sizes of the (metallic) core and (rocky) mantle.

An international team led by a researcher from the Institute of Astrophysics of Andalusia (IAA-CSIC) has found two telluric planets orbiting, while partially eclipsing, the nearby dwarf star HD 260655.

The discovery was made combining space- and multiple ground-based facilities, in particular the CARMENES spectrograph at the Calar Alto 3.5 m telescope. These two newly found hot super-Earths are among the top 10 candidates for follow-up studies of their atmospheres. 

In the last 30 years, over 5000 planets have been discovered outside our Solar System. Still, only a small fraction of these exoplanets were found to be telluric, that is, rocky, like Mercury, Venus, the Earth, and Mars.

Combining data from the CARMENES spectrograph at Calar Alto and from the NASA TESS satellite, among others, a team of astronomers led by Rafael Luque (Institute of Astrophysics

Almería (Spain), May 24th, 2022

UCM and IAA-CSIC co-lead TARSIS, the future instrument for the 3.5 m telescope at Calar Alto. TARSIS has unique characteristics, in particular its capacity to detect near ultraviolet light and its unprecedented field of view, along with an ambitious observational survey of galaxy clusters (CATARSIS) tailored to it. TARSIS and CATARSIS will maintain the largest optical telescope in the European mainland at the forefront of astronomy.

Almería (Spain), February 18th, 2022

A team of Spanish researchers, coordinated by the University of Seville, with participation of Calar Alto Observatory and the Institute of Astrophysics of Andalusia (IAA-CSIC), was able to detect the coronavirus that causes COVID-19 using a new optical methodology. This tool could be potentially usable for massive, fast and easy-to implement screening.

A multidisciplinary collaboration, whose first results are published in the journal Scientific Reports, from the Nature Group, has obtained a sensitivity of 100% and a specificity of 87.5% in the detection of SARS-CoV-2 in nasopharyngeal exudate (the same samples used in a PCR test) from symptomatic people. It has also been possible to detect the presence of SARS-CoV-2 in fresh saliva of asymptomatic people, as well as to detect, differentiate and quantify two types of synthetic viruses (lentiviruses and synthetic coronaviruses) in two biofluids (saline solution and artificial saliva).
