PODEMOS SER COMPETITIVOS EN I+D+i , también ahora (Análisis de un caso de éxito: ASTROFÍSICA ESPAÑOLA) Francisco Sánchez Foro España Innova, 6/2/2012 No voy a hablarles esta mañana ni de planetas extrasolares, ni de estrellas de neutrones, agujeros negros, materia obscura, energía obscura, ni de ninguna otra maravilla del misterioso Universo al que pertenecemos. Tampoco es mi intención hacer un discurso apologético, resaltando los mil y un beneficios de la Ciencia y del poder de la investigación para promover la competitividad y la recuperación económica, (todos los aquí presentes ya lo

Informe Semanal ha viajado al Instituto de Astrofísica de Canarias para conocer los últimos proyectos que nos acercan más al Sol.

La colaboración SDSS-III, en la que participa el IAC, anuncia nuevos resultados del proyecto BOSS sobre la enigmática energía oscura y los neutrinos, las elusivas partículas subatómicas claves para entender tanto el origen del universo como las supernovas

We report the detection of an orbital period decay of (dP/dt)= -1.83+-0.66 ms yr–1  in the black hole X-ray binary XTE J1118+480. This corresponds to a period change of –0.85 ± 0.30 μs per orbital cycle, which is ~150 times larger than expected from the emission of gravitational waves. These observations cannot be reproduced by conventional models of magnetic braking even when including significant mass loss from the system. The spiral-in of the star is either driven by magnetic braking under extremely high magnetic fields in the secondary star or by a currently unknown process, which will

Recent near-infrared data have contributed to the discovery of new (obscured) massive stellar clusters and massive stellar populations in previously known clusters in our Galaxy. These discoveries lead us to view the Milky Way as an active star-forming machine. Aims: The main purpose of this work is to  determine physically the main parameters (distance, size, total mass and age) of Masgomas-1, the first massive cluster discovered by our systematic search programme. Methods: Using near-infrared ( J, H, and K S) photometry we selected 23 OB-type and five red supergiant candidates for multi

Stars are generally spherical, yet their gaseous envelopes oftenappear non-spherical when ejected near the end of their lives. Thisquirk is most notable during the planetary nebula phase when theseenvelopes become ionized. The most popular explanation is that theasymmetry, and in particular the formation of highly collimatedstructures such as the precessing jets observed in a number ofnebulae, is caused by interactions in a binary system. The study ofthe prototypical planetary nebula Fleming 1 with the VLT telescopedemonstrates for the first time that the hypothesis iscorrect. Indeed, it is
