Researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), publish today in the journal Astronomy & Astrophysics the first results of a detailed study of nearly a thousand blue supergiants in the Milky Way. This is the biggest sample of stars of this type which has been studied until now. The study has used over 15 years of high quality observations taken mainly with the NOT and Mercator telescopes at the Roque de los Muchachos Observatory in La Palma. The analysis of these data will allow researchers to improve their knowledge of the evolution ofAdvertised on

After comparative studies of a sample of almost 50 open stellar clusters of different ages in the Milky Way, research led by the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) with collaboration by the Polytechnic University of Cartagena, shows that when these star clusters age they lose the majority of their less massive members. This result confirms that there are internal dynamical processes in open clusters caused by their long journeys through the Galaxy, which bring about the expulsion of these low mass stars. The study, published in the journalAdvertised on

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 bigAdvertised on
