RESUMEN

Anunciamos la publicación de un catálogo de modelos físicos de discos de acreción alrededor de estrellas jóvenes, irradiados por la estrella central, los cuales están basados en las técnicas de modelización de D'Alessio et al. El catalogo WWW incluye ~ 3000 modelos de disco para diferentes estrellas centrales, tamaños del disco, inclinaciones del disco, contenidos de polvo y tasas de acreción de masa. Para cada uno de ellos, los perfiles radiales de las propiedades físicas del disco y distribuciones espectrales de energía sintéticas se pueden consultar o descargar desde la página web para compararlos con observaciones. El catálogo está accesible en http://cfa-www.harvard.edu/youngstars/dalessio/(EEUU), http://www.astrosmo.unam.mx/~dalessio/ (México), y en http://www.laeff.esa.es/models/dalessio/(España).

 

ABSTRACT

We announce the release of a catalog of physical models of irradiated accretion disks around young stars based on the modelling techniques by D'Alessio et al. The WWW catalog includes ~ 3000 disk models for different central stars, disk sizes, inclinations, dust contents and mass accretion rates. For any of them, radial profiles of disk physical parameters and synthetic spectral energy distributions can be browsed and downloaded to compare with observations. The catalog can be accessed at http://cfa-www.harvard.edu/youngstars/dalessio/ (US), http://www.astrosmo.unam.mx/~dalessio/ (Mexico), and at http://www.laeff.esa.es/models/dalessio/ (Spain).

Key Words: Accretion disks — Astronomical data bases — Stars: Pre-main sequence.
