cds-question@unistra.frsubdwarf-starsultraviolet-photometryThe hot subdwarf (sd) stars in the Palomar Green (PG) catalog of ultraviolet excess (UVX) objects play a key role in investigations of the frequency and types of binary companions and the distribution of orbital periods. These are important for establishing whether and by which channels the sd stars arise from interactions in close binary systems. It has been suggested that the list of PG sd stars is biased by the exclusion of many stars in binaries, whose spectra show the CaII K line in absorption. A total of 1125 objects that were photometrically selected as candidates were ultimately rejected from the final PG catalog using this K-line criterion. We study 88 of these "PG-Rejects" (PGRs), to assess whether there are significant numbers of unrecognized sd stars in binaries among the PGR objects.2009AJ....138..606Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/138/606CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/207 : Palomar-Green catalog UV-excess stellar objects (Green+ 1986)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/138/606https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/138/606http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/138/606https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/138/606https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/138/606http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/138/606GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/138/606/pgr (PGR sources: GALEX UV-photometry, V-band photometry, and 2MASS counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/138/606/pgr?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/138/606/pgr?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/138/606/pgr?GETtext/xml+votable180.050000true0.535252.85783330.0055555555555555566/17 29 198 203 206 553 556 4920 4984 4997 5712 5782 5810 6025 6044 6060 6064 6074 6077 6500 6516 6517 6519 6525 7202 7208 7283 7290 7366 7386 7454 7561 7564 7585 7771 12294 12625 12627 13392 18027 18090 18117 18120 18126 18134 18143 18168 18169 18339 18366 18421 18804 18896 19166 19262 19446 19449 19450 19463 19468 19486 19614 19715 19723 19729 19772 19779 19781 19783 19785 19789 19794 19800 19835 19984 20151 20152 20157 20203 20206 20274 23195https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/138/606?format=asciiUVdefaultJ/AJ/138/606/pgrPGR sources: GALEX UV-photometry, V-band photometry, and 2MASS counterpartsrecnoRecord number assigned by the VizieR team.
