The Instituto de Astrofisica de Canarias hosted this week the global meeting of the members of the European project The Whole Sun , a project approved and funded by the European Research Council (ERC) as part of its Synergy Grant calls. The duration of the project is seven years (from 2019 to 2026) and its full title is: “The whole Sun: untangling the complex physical mechanisms behind our eruptive star and its twins”. The main objective of the ERC’s Synergy Grant calls is to promote the joint work of groups of researchers in different European institutions so that all the necessary tools

A study published today in Nature Astronomy , in which a researcher from the IAC has participated, outlines the discovery of an extremely rare type of binary system composed of two high mass white dwarfs. The two stars are so close together that they will eventually collide resulting in a supernova explosion which, due to its proximity to the Earth, will appear ten times brighter than the Moon. Type 1a supernovae are a class of cosmic explosion often used as "standard candles" to measure the expansion of the Universe. They occur when a white dwarf exceeds the Chandrasekhar mass - the limit

An international team of researchers, including staff from the Instituto de Astrofísica de Canarias (IAC), has discovered a planetary nebula that destroyed its own planetary system, conserving the remaining fragments in the form of dust orbiting its central star. To date, more than 5000 exoplanets have been discovered orbiting stars of all kinds and almost every stage of stellar evolution. However, while exoplanets have been discovered around white dwarfs – the final stage in the evolution of low- and intermediate-mass stars like the Sun, no exoplanets have been detected in the previous
