From 18 to 20 October, scientists from the USA, Japan and Europe meet at the Instituto de Astrofísica de Canarias (IAC) to discuss the results of the third CLASP space experiment to study the magnetic field of the solar chromosphere and the science of future solar missions. Several years ago, an international scientific team began developing a series of novel suborbital space experiments, with the goal of measuring the intensity and polarization of the ultraviolet radiation of the Sun emitted from one of the outer layers of its atmosphere, the chromosphere, very close to the base of the

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 journal

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
