The Berkeley Extreme and Far-UV Spectrometer (BEFS), flew on the
Orbiting and Retrievable Far and Extreme Ultraviolet Spectrograph (ORFEUS)-SPAS I
and II space shuttle missions in 1993 and 1996, returning high-resolution (/3000)
FUV spectra (900-1200 Å) of 75 astrophysical objects from the first flight and more
than 100 from the second. EUV spectra (400-900 Å) were obtained for a subset of these
targets.
The BeSS database assembles classical Be star spectra obtained by professional and amateur astronomers at any wavelength, epoch, and spectral resolution.
This service exposes the light curves of stars produced by the Bochum
Galactic Disk Survey; several million light curves are provided in the
SDSS i and r bands. The lightcurves are published per-band and are
also available through obscore.
The BT-COND Model grid of theoretical spectra. Brown dwarfs/extrasolar planets atmosphere models without irradiation and no dust opacity (no dust settling) but updated abundances. Wavelengths have been converted to air wavelengths.
The BT-DUSTY Model grid of theoretical spectra. Brown dwarfs/extrasolar planets atmosphere models without irradiation but including dust opacity (fully efficient dust settling) and updated abundances. Wavelengths have been converted to air wavelengths.
The NextGen Model grid of theoretical spectra; Gas phase only, valid for Teff > 2700 K. Updated opacities. Wavelengths have been converted to air wavelengths.
