Table information for 'wdsdss10.main'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: The catalogue WDSLOAN10 has been constructed by spectroscopically selecting white dwarfs and subdwarfs in the Sloan Digital Sky Survey Data Release 10. It offers Teff, log(g) and mass for hydrogen atmosphere white dwarf stars (DAs) and helium atmosphere white dwarf stars (DBs), and estimatives of calcium/helium abundances for the white dwarf stars with metallic lines (DZs) and carbon/helium for carbon dominated spectra DQs.

For a list of all services and tables belonging to this table's resource, see Information on resource 'New white dwarf stars in the SDSS-DR10'
