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 immense
La reconocida astrofísica Jocelyn Bell ha sido reconocida con la quinta estrella del Paseo de la Ciencia de Santa Cruz de La Palma, reconociendo su labor en defensa de la igualdad y los descubrimientos realizados. Un reconocimiento que ha sido simbólicamente entregado por el presidente del Cabildo de La Palma, Sergio Rodríguez, en un acto en el que ha participado la subdirectora del Instituto de Astrofísica de Canarias (IAC), Eva Villaver y el director del Festival Starmus, Garik Israelian. La subdirectora del IAC agradeció a Bell el trabajo científico realizado en toda su carrera y
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 recent
