    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

    A team of researchers, led by the Instituto de Ciencias del Patrimonio (Incipit-CSIC) and the Instituto de Astrofísica de Canarias (IAC), in collaboration with the team from the Arqueological Zone of Caral (Perú) led by Dr. Ruth Shady Solís, has established the relation between the position of the monuments of the Supe Culture (Perú), their orientations, and some astronomical and topographic features, which opens the way to the analysis of the way the inhabitants of this valley conceived space and time 5000 years ago. The results of the study have just been published in the journal Latin

  • Firma del acuerdo de gestión del Centro de Visitantes

    The Cabildo of La Palma, the Town Council of Garafía, and the Instituto de Astrofísica de Canarias (IAC), joined via a videoconference, signed an agreement to collaborate in the management of the future tourist centre which will be devoted to the popularization of Astronomy, and of the natural and cultural heritage of the highest point on the Island of La Palma, were the Roque de los Muchachos Observatory is sited. The President of the Cabildo of La Palma, Mariano Zapata, the Mayor of Garafía, Yeray Rodríguez, and the Director of the IAC Rafael Rebolo participated in the signing. Also

    Feedback-driven winds from star formation or active galactic nuclei might be a relevant channel for the abrupt quenching of star formation in massive galaxies. However, both observations and simulations support the idea that these processes are non-conflictingly co-evolving and self-regulating. Furthermore, evidence of disruptive events that are capable of fast quenching is rare, and constraints on their statistical prevalence are lacking. Here we present a massive starburst galaxy at redshift z=1.4, which is ejecting ~46% of its molecular gas mass at a startling rate of >10,000 solar masses

    Two astronomy networks are coming together to form the OPTICON-RadioNet PILOT (ORP), the Europe’s largest ground-based astronomy collaborative network that it will provide scientists with access to a wide range of instruments, promote training for young astronomers, and open the way to new discoveries. With €15 million in funding from the H2020 programme, the CNRS will coordinate the project, together with the University of Cambridge and the Max-Planck Institute for Radio Astronomy. The Instituto de Astrofísica de Canarias (IAC) participates with its observatories and in instrumental
