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.

YBC: tools to convert thoretical data into the photometry in many photometric systems. Tables of BC and variable extinction coefficients included.

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

Static databases

Newest databases:

pulsation: Periods and growth rates of long period variables. Codes and tables described in Michele Trabucchi's papers.

Cstars: COMARCS/COMA Cool Star Spectra and Photometry, including all data files from Aringer's papers.

Databases which have not been updated for a while:

The Padova database of evolutionary tracks and isochrones: a (somewhat outdated) repository of static files containing published tracks, isochrones, bolometric corrections, chemical yields, and additional unpublished material (plots, later releases, preprints, etc.).

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). Note: superseded by CMD and YBC.

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