An international collaboration, with the participation of the Instituto de Astrofísica de Canarias (IAC), determines with an unprecedented level of precision the mass, age and rotation profile of the core of a massive pulsating star. Known as HD 192575, it has been observed by the NASA space telescope TESS continuously for more than a year. The results shed new light on how such stars are internally structured and how they evolve until their death, when they explode as supernovae and form neutron stars and black holes. The scientific team has also used observations made with the Mercator

Research carried out by a scientific team from the University of Heidelberg (UH), the Instituto de Astrofísica de Canarias (IAC) and the National Autonomous University of Mexico (UNAM) has allowed them to solve the abundance discrepancy, a puzzle over 80 years old, about the chemical composition of the Universe. They find that the effect of the variations in temperatura in the large gas clouds where stars are born has led to the underestimation of the quantity of heavy elements in the Universe. The results have been published in the prestigious journal Nature . All the stars are born, live

The IAC researcher Susana Iglesias-Groth has discovered the existence of tryptophan, an amino acid essential for the formation of proteins and the develoment of living organisms, within a stellar system in the Perseus Cloud. She did this using data from the Spitzer Space Observatory. The results of this finding are published in the journal Monthly Notices of the Royal Astronomical Society. Tryptophan is one of the 20 amino acids considered essential for the formation of proteins, which are key macromolecules for the development of life on Earth. This amino acid has many spectral features in
