The Kurucz (1992) model atmospheres

Below are a description of, and links to, the Kurucz (1992) model atmospheres.

There are 1100 ASCII files, each containing the fluxes of a Kurucz (1992) LTE model atmosphere. Units are Angstroms for wavelengths and erg/s/cm/cm/A for fluxes. Listed are Astrophysical Fluxes (with a factor of pi). The table below gives the available log g values (x 10) and effective temperatures. All models are available for twice solar (p03), solar (p00), quarter solar (m06), and tenth solar metallicity (m10).

Nomenclature: txgymz.dat, where
x is the temperature from 4000 to 60000 (as below)
y is 10 x log(g) (available as below); and
z is one of the 4 available metallicities (p03, p00, m06, m10)

You can find individual files available for FTP on ftp.stsci.edu/science/starburst/Kurucz. For convenience, we have also created gzipped tar files grouped by metallicity. You can download these using the "Save Link as..." option on your browser.
