Cientos de personas se han acercado este fin de semana al Observatorio del Teide para participar en las tradicionales jornadas de puertas abiertas que organiza el Instituto de Astrofísica de Canarias coincidiendo con la semana del solsticio de verano. Esta actividad, organizada de forma conjunta por el Observatorio del Teide y por la Unidad de Comunicación y Cultura Científica (UC3) del IAC, forma parte de las tareas de divulgación que realiza el Instituto para que la ciudadanía pueda conocer de primera mano uno de los mejores observatorios del mundo, sus infraestructuras, el trabajo de su
Research led by the Instituto de Astrofísica de Canarias (IAC) has discovered that, in binary systems, stars that evolve into red giants change the way they rotate with their companions, making their orbits more circular. The result was achieved after studying nearly 1000 solar-like oscillating stars in binary systems, the greatest yield to date of such objects. For their identification, the third Gaia Data Release (Gaia-DR3) and NASA Kepler and TESS catalogs have been explored. The study has been published in the journal Astronomy and Astrophysics and has been selected as the most recent
The single star nearest to the Sun is called Barnard’s star. A team of researchers led by the Instituto de Astrofísica de Canarias (IAC), has recently detected a ‘sub-Earth’ orbiting it. This exoplanet, called Barnard b has at least half the mass of Venus and orbits rapidly around its star, so that its year lasts only a little over three Earth days. This new exoplanet is sixteen times nearer to Barnard’d star than Mercury is to the Sun, and has a surface temperature close to 125oC, so it does not have liquid water on its surface. This discovery, led by the IAC in collaboration with a number
