STEV index

Welcome to STEV, the OAPd server for stellar models. Here you'll find a series of web services related with stellar evolutionary tracks, isochrones, synthetic photometry, synthetic photometric data, and opacity tables.

Interactive services AESOPUS: Low-temperature Rosseland mean opacities on demand.

CMD: provides interpolated isochrones for any age and metallicity, as well as luminosity functions, integrated magnitudes, etc. The photometry can be produced for many different broad- and intermediate-band systems, including non-standard ones.

PARAM: Bayesian estimation of stellar parameters. Provides the most likely values of stellar mass, age, radius, surface gravity, etc., for a star of know photometry and distance (parallax).

TRILEGAL: a simulator of photometry for any galaxy field. The photometry can be produced for many different broad- and intermediate-band systems, including non-standard ones.

YZVAR form: stellar isochrones interpolated for any intermediate value of Y and Z (Bertelli et al. 2008).

Static databases

The Padova database of evolutionary tracks and isochrones: a (somewhat outdated) repository of static files containing published tracks, isochrones, bolometric corrections, chemical yields, and additional unpublished material (plots, later releases, preprints, etc.).

Newest databases:

Cstars: COMARCS/COMA Carbon Star Spectra and Photometry 2008, including all data files for the paper Aringer et al. (2009).

dustyAGB07: data files for the calibrated TP-AGB tracks from Marigo & Girardi (2007), and their related optical-to-far-IR isochrones (Marigo et al. 2008). It includes interstellar extinction coefficients as in Girardi et al. (2008).

YZVAR: stellar evolutionary tracks and isochrones for a large region of the Y-Z plane (Bertelli et al. 2008).
