On the FTP server there is a new directory “v2.0” containing the high resolution spectra for version 2.0 of the spectral library. The changes are as follows:
- extended towards higher temperatures (15,000 K)
- changed the values at which [alpha/Fe] is sampled
- extended the use of special line profiles, e.g. for Ca, down to 4000 K
- filled holes in the grid, especially the previously missing models at 5000 K
- added some models with logg=6.5 and logg=-0.5
The physical assumptions for the new spectra are the same as in version 1.0.
The other data products as the convolved grids, the specific intensities and so on will follow within the next couple of weeks.
Please continue citing the Husser et al. (2013) paper as before.
We upgraded the memory on the server and hopefully the problems are now gone.
Unfortunately we’re experiencing massive server problems at the moment due to insufficient memory. We’re in the process of upgrading it and hope that it will work again soonish. We apologize for any inconvenience.
Unfortunately it seems that some of the FITS headers in the files are wrong. All the units are given in [cgs], so:
- The mass (PHXMASS) is given in grams.
- The luminosity (PHXLUM) is given in erg/s.
Sorry for the inconvenience.
We’ve now also published the atmospheric structures for all our models. They are available for download as FITS binary tables with the columns tau, temp, pgas and rho.
We just made specific intensity spectra (a.k.a. the ‘full radiation field’) for all models in the base grid (i.e. [alpha/Fe]=0) available for download. They span the wavelength range from 500 to 26000 Angstrom with a sampling of 1 Angstrom. We provide the spectra for 78 different values for the angle mu.
Furthermore we’ve convolved those specific intensity spectra with commonly used filters to be used for limb darkening applications. The results are also available for download. In case you need different filters, please send us their response curves.
After some considerations we’ve decided to allow FTP access for the download of the spectra. From now on, both the high and the medium resolution spectra are available via FTP at:
If there are any problems, please let us know.
Unfortunately there has been an error in the published paper. The reference that we give for the STELIB is obviously wrong, the correct one is this:
STELIB: A library of stellar spectra at R ~ 2000
Le Borgne, J.-F.; Bruzual, G.; Pelló, R.; Lançon, A.; Rocca-Volmerange, B.;
Sanahuja, B.; Schaerer, D.; Soubiran, C.; Vílchez-Gómez, R.,
2003, A&A 402, 433
The astro-ph version has already been corrected, but it was too late for the A&A publication…
We have just uploaded an update to the server that consists of two parts:
- The missing interpolated spectra, 325 in total. A full list can be found here. All these spectra contain a FITS keyword “INTERPOL” with the value “T” for easy identification.
- Since the start of this website, 1365 additional spectra have been calculated successfully that we also uploaded now. See this list for details.
The new spectra are available individually in high resolution and have been added to the archives with the medium resolution spectra.
Last week we noticed that all the interpolated spectra in the library are missing in the download section. We are currently working on an update and will publish those spectra on this website soonish.
