We have measured C II and O II recombination lines in several H II regions of low-metallicity dwarf galaxies. These objects show lower C/O ratios than H II regions in spiral galaxies, indicating different chemical evolution histories.

Recently, it has been showed that (136108) 2003 EL61 and its biggest satellite S/2005 (136108) 1,(55636) 2002 TX300, (13308) 1996 TO66 , OP32, 1995 SM55 and 2005 RR43 are part of a population trans-netunian objects (TNOs) clustered in the space of orbital parameters (41.6

CARMENES, Calar Alto high-Resolution search for M dwarfs with Exo-earths with a Near-infrared Echelle Spectrograph, is a study for a next-generation instrument for the 3.5 m Calar Alto Telescope to be designed, built, integrated, and operated by a consortium of nine German and Spanish institutions. Our main objective is finding habitable exoplanets

CASTAway is a mission concept to explore our Solar System's main asteroid belt. Asteroids and comets provide a window into the formation and evolution of our Solar System and the composition of these objects can be inferred from space-based remote sensing using spectroscopic techniques. Variations in composition across the asteroid populations

A catalogue of light curve solutions of contact binary stars has been compiled. It contains the results of 159 light curve solutions. Properties of contact binary stars were studied by using the catalogue data. As it is well known since Lucy's (1968ApJ...151.1123L, 1968ApJ...153..877L) and Mochnacki's (1981ApJ...245..650M) works, primary components
