A pioneering study from the Instituto de Astrofísica de Canarias (IAC) which combines laboratory chemistry with astrophysics, has shown for the first time that grains of dust formed by carbon and hydrogen in a highly disordered state, known as HAC, can take part in the formation of fullerenes, carbon molecules which are of key importance for the development of life in the universe, and with potential applications in nanotechnology. The results are published as a Letter to the Editor in the prestigious journal Astronomy & Astrophysics. Fullerenes are carbon molecules which are very big
An international team of researchers, with participation from the Instituto de Astrofísica de Canarias, has discovered an extremely dense Neptune-sized planet, which challenges the conventional theories about the formation and evolution of planets. It was first identified with NASA’s TESS satellite, and the present studies were made with the HARPS-N spectrograph on the Telescopio Nazionale Galileo (TNG), at the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands). The results of the study have been published in the journal Nature. It is called TOI-1853b and is really
An international piece of research, led by the Instituto de Astrofísica de Canarias (IAC) has found clues to the nature of some of the brightest and hottest stars in our Universe, called blue supergiants. Although these stars are commonly observed, their origin has been an old puzzle that has been debated for several decades. By simulating novel stellar models and analysing a large data sample in the Large Magellanic Cloud, IAC researchers have found strong evidence that most blue supergiants may have formed from the merger of two stars bound in a binary system. The study is published in the
