An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC), the University of Liège and collaborators in UK, Chile, the USA, and Europe, has discovered a transiting giant planet orbiting the smallest known star to host such a companion — a finding that defies current theories of planet formation. The host star, TOI-6894 , is a red dwarf with only 20% the mass of the Sun , typical of the most common stars in our galaxy. Until now, such low-mass stars were not thought capable of forming or retaining giant planets. But as published today inAdvertised on -
An international team led by Cristina Ramos Almeida, a researcher at the Instituto de Astrofísica de Canarias (IAC), has used the James Webb Space Telescope (JWST) to observe five dust-obscured quasars — and the results offer new insights into how galaxies and their central supermassive black holes may evolve. The study is published today in the journal Astronomy & Astrophysics . The energy released by supermassive black holes at the centres of galaxies is a fundamental ingredient in regulating the formation of new stars, and thus galaxy growth. This occurs during an active phase, usuallyAdvertised on -
