Information on Service 'SDSS-DR10 white dwarfs catalog'

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 service's resource, see Information on resource 'New white dwarf stars in the SDSS-DR10'

Service Documentation

We report the discovery of 9089 new spectroscopically confirmed white dwarfs and subdwarfs in the Sloan Digital Sky Survey Data Release 10. We obtain Teff, log(g) and mass for hydrogen atmosphere white dwarf stars (DAs) and helium atmosphere white dwarf stars (DBs), and estimate the calcium/helium abundances for the white dwarf stars with metallic lines (DZs) and carbon/helium for carbon dominated spectra DQs. We found 1 central star of a planetary nebula, 2 new oxygen spectra on helium atmosphere white dwarfs, 71 DQs, 42 hot DO/PG1159s, 171 white dwarf+main sequence star binaries, 206 magnetic DAHs, 327 continuum dominated DCs, 397 metal polluted white dwarfs, 450 helium dominated white dwarfs, 647 subdwarfs and 6888 new hydrogen dominated white dwarf stars.

Overview

You can access this service using:

static -- static (i.e. prepared) data or custom client-side code; probably used to access ancillary files here
form -- allows access via an HTML form
scs.xml -- a standard SCS interface as defined by the IVOA to access catalog-type data; SCS clients use http://vo.bsdc.icranet.org/wdsdss10/q/cone/scs.xml? to access the service

This service is published as follows:

Within the set(s) ivo_managed with the renderer availability
Within the set(s) ivo_managed with the renderer capabilities
Within the set(s) local with the renderer form
Within the set(s) ivo_managed with the renderer scs.xml
Within the set(s) ivo_managed with the renderer tableMetadata
Within the set(s) ivo_managed with the renderer tap

local means it is listed on our front page, ivo_managed means it has a record in the VO registry, gavo means it is within GAVO's service registry.
