Un equipo, con participación del Instituto de Astrofísica de Canarias (IAC) ha descubierto, por casualidad, una docena de sistemas estelares binarios con peculiaridades jamás vistas.

El hallazgo, que cuenta con la participación del IAC, sugiere que hay más agua de la que se pensaba en la región interna del Sistema Solar y aporta nuevas evidencias a la teoría que postula que el agua llegó a la Tierra a través del impacto de asteroides y cometas.

Este espectáculo único será retransmitido en directo, con la participación del IAC, a travésde la página web www.eclipsesolar.es

Mario Joao Monteiro is a theorist of the highest order. An expert in solar and stellar modelling, his current scientific interests are centred on the seismic analysis of the internal structure and evolution of solar-type stars. He aims to determine the fundamental stellar parameters necessary for a better understanding of how stars evolve from the pre-main sequence to the most advanced evolutionary stages. Since 2006 he has been the Director of the Centro de Astrofísica da Universidade do Porto (CAUP). He plays a distinguished part in the Kepler mission, in charge of the modelling of solar

Thierry Appourchaux is a mathematician by training and an expert in statistics. His experience in instrumentation and data analysis in Helio- and Asteroseismology is outstanding: he heads the group dedicated to data analysis for the CoRoT (COnvection ROtation and planetary Transits) mission and the group studying the characterization of the acoustic modes of solar-type stars for the Kepler mission. He also leads the Asteroseismology analysis team within the PLATO (PLAnetary Transits and Oscillations of stars) consortium.A specialist in the characterization of the acoustic modes of the Sun

Jorgen Christensen-Dalsgaard, professor of Helio- and Asteroseismology at Aarhus University (The Netherlands), seems to be interested in all aspects of these two disciplines. Among other activities, he heads SONG (Stellar Observations Network Group), an international network of terrestrial telescopes for continuous observation of the stars, and he directs the KASC ( Kepler Asteroseismic Science Consortium), which studies asteroseismological data gathered by Kepler. Another of his achievements is to have persuaded NASA to include Asteroseismology as part of the Kepler mission. This year marks
