Beginning of ReadMe : B/pollux POLLUX database of synthetic stellar spectra (Palacios+ 2010-2021) ================================================================================ The POLLUX database of synthetic stellar spectra. Palacios A., Gebran M., Josselin E., Martins F., Plez B., Belmas M., Lebre A. <Astron. Astrophys. 516, A13 (2010); 545 A67 (2021)> =2010A&A...516A..13P +2021A&A...545A..67B ================================================================================ ADC_Keywords: Spectroscopy ; Models Keywords: astronomical data bases: miscellaneous - stars: general - techniques: spectroscopic Abstract: Synthetic spectra are needed to determine fundamental stellar and wind parameters of all types of stars. They are also used for the construction of theoretical spectral libraries helpful for stellar population synthesis. Therefore, a database of theoretical spectra is required to allow rapid and quantitative comparisons to spectroscopic data. We provide such a database offering an unprecedented coverage of the entire Hertzsprung-Russell diagram. We present the POLLUX database of synthetic stellar spectra. For objects with Teff<=6000K, MARCS atmosphere models are computed and the program TURBOSPECTRUM provides the synthetic spectra. ATLAS12 models are computed for stars with 7000K<=Teff<=15000K. SYNSPEC gives the corresponding spectra. Finally, the code CMFGEN provides atmosphere models for the hottest stars (Teff>25000K). Their spectra are computed with CMF_FLUX_. STAGGER 3D RHD models are computed for stars with 3900K<=Teff<=7000K. OPTIM3D gives the corresponding spectra. MARCS (from the AMBRE project, https://doi.org/10.1051/0004-6361/201219330) and ATLAS12 data consist of high resolution (R>150000) optical spectra in the range 3000 to 12000AA for a large variety of metallicities and chemical compositions. The CMFGEN data are high resolution (R > 150000) spectra in the optical, the UV and the IR domains and spectral energy distributions extending from the UV to near-IR ranges at solar metallicity and at the subsolar metallicities of Z=1/5Zsun and Z=1/30Zsun (https://arxiv.org/pdf/2010.13430.pdf). The OPTIM3D-STAGGER data are medium resolution (R=20000) spectra in the optical, the UV and the IR domains from 2000 to 200000AA. The OPTIM3D-Gaia data are very high resolution spectra (R=300000) in the Gaia-RVS spectral domain (from 8395AA to 8905AA ) (https://doi.org/10.1051/0004-6361/201732147). All the spectra cover the HR diagram at various metallicities. We propose a wide variety of synthetic spectra for various types of stars in a format that is compliant with th Virtual Observatory standards. A user-friendly web interface allows an easy selection of spectra and data retrieval. Upcoming developments will include an extension to a large range of metallicities and to the near-IR high resolution spectra, as well as a better coverage of the HR diagram, with the inclusion of models for Wolf-Rayet stars and large datasets for cool stars. The POLLUX database is accessible at http://pollux.oreme.org/ and through the Virtual Observatory. Description: A description of the data (high resolution synthetic spectra and spectral energy distributions) in the POLLUX database is presented in the form of an ascii table providing parameters that can be queried (Teff, logg, code, metallicity) and giving the filename and URL where a fits file can be retrieved.
