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 Instituto de Astrofísica de Canarias (IAC) and the KU Leuven , Belgium, have amplified their framework of collaboration in astrophysical research. The two institutions have signed an agreement which gives continuity to the operations of the Mercator Telescope at the Roque de los Muchachos Observatory (ORM), which started in 2002, and whose work will be strengthened by the installation of a new instrument called MARVEL (Mercator Array for Radial Velocities). Mercator is a semi-robotic telescope with a 1.2 metre primary mirror. Its name comes from that of the famous Flemish cartographerAdvertised on -
A new international study, using observations from the Gran Telescopio Canarias at the Roque de los Muchachos Observatory on La Palma, has identified a plasma bubble as the source of the persistent emission observed in some of the so-called fast radio bursts (FRBs), one of the most powerful and unknown cosmic events in the Universe. The data also allow researchers to constrain the nature of the “engine” powering these mysterious sources. The results are published today in Nature. Discovered just over a decade ago, fast radio bursts (FRBs) emit millisecond-long pulses that release an immenseAdvertised on
