    The exoplanet satellite hunter CHEOPS of the European Space Agency (ESA), in which the Instituto de Astrofísica de Canarias (IAC) is participating along with other European institutions, has unexpectedly detected a third planet passing in front of its star while it was exploring two previously known planets around the same star. This transit, according to researchers, will reveal exciting details about a strange planet “without a known equivalent”.

    In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 and 0.45 solar masses. In this context, a team of researchers led by Borja Toledo Padrón, a Severo Ochoa-La Caixa doctoral student at the Instituto de Astrofísica de Canarias (IAC), specializing in the search for planets around this type of stars, has discovered a super-Earth orbiting the star GJ 740, a red dwarf star situated some 36 light years

    For astronomers one of the biggest obstacles is the darkness of the Universe itself, above all the darkness caused by the gas and dust which surround active galactic nuclei, or AGN. These nuclei emit a huge quantity of energy produced by the supermassive black hole onto which matter falls at a considerable rate. The accretion processes are fundamental for the evolution of active galaxies. However these nuclei often remain hidden by the dusty structures, called tori, which surround the central black hole. Studyuing the properties of this circumnuclear dust, the accretion processes, and

    The journal Nature Communications today is publishing the discovery of a new type of stars, very rich in phosphorus, which could help to explain the origin of this chemical element in our Galaxy. This achievement has been made by astronomers of the Instituto de Astrofísica de Canarias (IAC) and researchers in computer science from the Centre for Research in Information and Communication Technology (CITIC) at the University of La Coruña (Galicia).

  • Severo Ochoa Centre of Excellence Qualification

    The Ministry of Science and Innovation published yesterday the provisional resolution of the qualification of the Centres and Units of Excellence, granting the Instituto de Astrofísica de Canarias the recognition as a Centre of Excellence for the third consecutive time. The National Research Agency (AEI for its Spanish initials), which depends on the Ministry of Science and Innovation, has published the provisional resolution awarding the new Qualifications of the Severo Ochoa Centres of Excellence, whose aim is to recognize, reward, and promote high level scientific research at the Spanish

    Researchers from the Instituto de Astrofísica de Canarias (IAC) and the Istituto Nazionale di Astrofisica (INAF, Italy) have shown that massive early-type galaxies keep on forming stars, even though at a very slow rate. The results of this work, whose first author is the doctoral student at the IAC/ULL Núria Salvador-Rusiñol, are published today in the journal Nature Astronomy. Elliptical and lenticular galaxies (collectively called Early-Type galaxies) are the oldest galaxies in the Universe. They are also the most massive galaxies in the Universe, reaching up to 100 times the mass of the
