  • Se ha descubierto un compañero de unas 14 M Jup situada a 670 UA de UscoCTIO108, una enana marrón de 60 M Jup perteneciente a la joven asociación de Upper Scorpius.  Se trata del objeto de masa planetaria menos luminoso y masivo, detectado por imagen directa, después de 2M1207b. Los datos fotométricos y espectroscópicos que hemos obtenido, ópticos e infrarrojos, nos han permitido confirmar que tanto la primaria como la secundaria son objetos muy fríos, con Teff estimadas de 2700 y 2100K, respectivamente, y que se trata de miembros muy jóvenes de la asociación. La existencia de estos objetos

  • The sample of metal rich stars with and without planets has been extended in 2007 and the stellar parameters and metallicities have been obtained. The first study of kinematics of planet host stars has been completed. Our new results confirm the metal rich nature of stars with planets.The observed abundances  in  XTE J1118+480 together with kinematical characteristics allowed us to conclude that the compact object has formed in a supernova explosion. This system has travelled far from its original location and is currently located in the Galactic halo.
