Científicos del IAC han participado en el descubrimiento de un planeta extrasolar inusualmente denso, con 1,5 radios terrestres, pero 8 veces más masivo que la Tierra. Este planeta pone de relieve que hay otros mundos alrededor de otras estrellas con propiedades extremas y cuya formación aún resulta un misterio

Maria Bergemann, astrophysicist at the Max Planck Institute for Astronomy in Heidelberg (Germany), is one of the invited professors at the XXIX Canary Islands Winter School of Astrophysics organized by the Instituto de Astrofísica de Canarias (IAC) in collaboration with the University of La Laguna (ULL). Her classes will be about a very specific type of stars, which are characterized by their temperature, called "late-type stars" and the phenomena and physics that govern them, as well as the challenges posed by these stars from the point of view radiative transport, main topic of the School

His interest about the radiative transfer began in a lecture about "Stellar Atmospheres" he attended when he was studying his Physics degree. He was previously interested in particle physics but he liked the approach of quantitative spectroscopy which connects theory and observations and he wrote his Diploma thesis on radiative transfer in expanding atmospheres. Nowadays, Jo(achim) Puls is professor and researcher in the Universitätssternwarte der LMU München, where he works with his team investigating about radiative transfer in early-type stars and related problems, with many international

Giuseppe Bono, astrophysicist and associate professor of the Department of Physics at the Università degli Studi di Roma "Tor Vergata" (Italy), is a long-standing collaborator of the Instituto de Astrofísica de Canarias (IAC), either as visiting researcher or teacher in the Winter School that this centre organises in collaboration with the University of La laguna (ULL). In this edition, he will dedicate his talks to near-infrared high resolution spectroscopy of variable stars. That seems a difficult subjetc, but he assures that the accurate scattering of changing light emitted in that

Our planet becomes too small for some scientists, therefore they dedicate their lives to study other worlds much larger than Earth and those that are so massive that they almost become a star: giant planets and brown dwarfs. Mark S. Marley, scientist at the NASA Ames Research Center in the Space Sciences Division, computes models of their atmospheres and he is helping to plan for space missions, such as NASA's WFIRST and LUVOIR, for their characterization. He will dedicate his talks to this topic at the XXIX Canary Islands Winter School of Astrophysics, organized by the Institute of

Una investigación publicada recientemente y liderada por una estudiante de doctorado del Instituto de Astrofísica de Canarias (IAC) y la Universidad de La Laguna (ULL), explica la formación de la barra estelar de esta galaxia vecina de la Vía Láctea
