El Catálogo Colectivo reúne los registros del material que posee cada una de las
bibliotecas de la Universidad Nacional de Córdoba, pudiendo encontrarse colecciones
especializadas y actualizadas en todas las áreas del conocimiento; lo que permite una
amplia visibilidad y garantiza el acceso al patrimonio documental de la Universidad.
Se encuentra disponible para toda la comunidad académica: estudiantes, docentes,
egresados e investigadores.
Si formas parte de la comunidad de la UNC también podés solicitar préstamos de material,
a cualquier biblioteca universitaria, utilizando el servicio de préstamo interbibliotecario,
independientemente de la facultad a la que pertenezcas, la carrera que curses o la cátedra
que dictes.

Abstract: In the late ’80s an infrared excess (IR) around a white dwarf star (WD) was detected, which was attributed to the presence of a dusty circumstellar disk. In recent years, thanks to Spitzer, the number of WDs with excesses has increased significantly. In this contribution we present
the modeling of the spectral energy distributions (SEDs) of a sample of 29 WDs having IR excesses. This model allows us to derive the mass and the internal and external radii of the dusty disk, for a given chemical composition. The location of this ring is compared with the Habitability
Zone (HZ) of each WD in the sample. In addition, the dimensions and masses of these rings are compared with those around main sequence stars, commonly known in the literature as debris disks.
