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

Research carried out by a scientific team from the University of Heidelberg (UH), the Instituto de Astrofísica de Canarias (IAC) and the National Autonomous University of Mexico (UNAM) has allowed them to solve the abundance discrepancy, a puzzle over 80 years old, about the chemical composition of the Universe. They find that the effect of the variations in temperatura in the large gas clouds where stars are born has led to the underestimation of the quantity of heavy elements in the Universe. The results have been published in the prestigious journal Nature . All the stars are born, live
