Using observations of Spitzer/IRAC, we report the serendipitous discovery of excess infrared emission from a single white dwarf PG 0010+280. At a temperature of 27,220 K and a cooling age of 16 Myr, it is the hottest and ...

La galaxia espiral M83, una SBb a tan sólo 4,5 Mpc, posee el núcleo starburst más cercano. En esta tesis se presenta un estudio multibanda, utilizando diversas técnicas de espectroscopía 2D-3D.

En este trabajo se presenta una búsqueda de Planemos (Planetary Mass Objects) en la nube oscura L 1495 en el complejo molecular de Tauro. Se emplean observaciones en las bandas K(2.2 μm) y H(1.6 μm) obtenidas con la cámara ...

We report here the infrared and Raman spectra of [Re(CN)5NO]3- complex as guest diluted in the KCl crystal lattice. According to the chemical analysis, the anion concentration in the KCl host matrix is in excess of 2% (in ...

94 Ceti is a triple star system with a circumprimary gas giant planet and far-infrared excess. Such excesses around main sequence stars are likely due to debris discs, and are considered as signposts of planetary systems ...

An improved high-resolution and deep A(Ks) foreground dust extinction map is presented for the Galactic disc area within 295 degrees less than or similar to l less than or similar to 350 degrees, -1.0 degrees less than or ...
