Research led by the Instituto de Astrofísica de Canarias (IAC) has discovered that, in binary systems, stars that evolve into red giants change the way they rotate with their companions, making their orbits more circular. The result was achieved after studying nearly 1000 solar-like oscillating stars in binary systems, the greatest yield to date of such objects. For their identification, the third Gaia Data Release (Gaia-DR3) and NASA Kepler and TESS catalogs have been explored. The study has been published in the journal Astronomy and Astrophysics and has been selected as the most recentAdvertised on -
The European Southern Observatory (ESO) has signed an agreement with an international consortium of institutions, including the Instituto de Astrofísica de Canarias (IAC), the Instituto de Astrofísica de Andalucía (IAA) and the Centro de Astrobiología de Madrid (CSIC-INTA), for the design and construction of ANDES, the ArmazoNes high Dispersion Echelle Spectrograph. The instrument will be installed on ESO’s Extremely Large Telescope (ELT). It will be used to search for signs of life in exoplanets and look for the very first stars, as well as to test variations of the fundamental constants ofAdvertised on -
A team of scientists led by the Observatory of Munich University and the Instituto de Astrofísica de Canarias have obtained direct visualization of the process of feeding the supermassive black hole at the centre of the Andromeda galaxy. The study reveals the existence of long filamentary structures of gas and dust which move in a spiral starting at a distance from the black hole and ending up at the black hole itself. The results, which have been published in the Astrophysical Journal, were obtained using images from the Hubble and Spitzer space telescopes. The Andromeda Galaxy, which isAdvertised on
