The confirmation of the first super-Earth

Leave a comment

I have to confess that sometimes I am very tired of my trips: conferences, workshops, meetings, observing runs… I hate airports, I do not like the security and the waste of time, and I would prefer to avoid the effect of all these trips in my social life, since I spend a significant amount of time away.

However … sometimes (or many) is wonderful.

I am in Barcelona, for the conference “Pathways toward habitable exoplanets”. Today, a member of the Corot/HARPS team has announced the confirmation by radial velocities techniques of the first super-planet: Corot-7b, and the detection of a second planet around the same star. they should have masses of 4.8 and 8.4 earth masses, and due to their very short orbital periods (0.89 and 3.7 days), they should be very exotic, with a huge difference between the hemisphere always facing the star (about 200 K) and the night side, almost at 50 .

About dbarrado

Born in Madrid, Spain, David Barrado completed a degree in physics, specializing in astrophysics, at the Universidad Complutense de Madrid. At this same university he started work on a doctorate that he would go on to complete at the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge (USA). He then spent several years as a post-doctoral researcher at a number of institutes in the United States (including as a Fulbright scholar during his time at CfA), Germany (Max-Planck Institut für Astronomie, in Heidelberg) and Spain (Universidad Autónoma de Madrid). David now works at the European Space Astronomy Center (ESAC, Madrid) as a member of the National Technical Aerospace Institute (INTA), part of the Astrobiology Center (CAB), a combined institute made up of INTA and the Center for Higher Scientific Research (CSIC). With the INTA team he led research on the MIRI, an infrared instrument that will fly with the forthcoming space telescope, the JWST. He has also been involved in the development of a number of other astronomical instruments. For two years he was head of the Stellar and Exoplanets Astrophysics Laboratory, as a member of the CAB, and later Director of the Hispano-German Astronomy Center observatory in Calar Alto for three years. His research interests focus on the properties of stars in open star clusters, as well as detecting and characterizing substellar objects and exoplanets. More generally he has specialized in studying the formation of stars and planetary systems using various observational techniques: from visible light to distant infrared, using images and spectroscopes, via both terrestrial and space telescopes. This observation work has seen him publish close to one hundred and fifty articles in prestigious scientific journals. He also combines his research with tireless outreach activities. With Spanish blog, Cuaderno de Bitacora Estelar (see http://www.madrimasd.org/blogs/astrofisica/) has a very large audience.
