cds-question@unistra.frdwarf-starsinfrared-sourcesinfrared-astronomyspectroscopyVega-like sources are main-sequence stars that exhibit IR fluxes in excess of expectations for stellar photospheres, most likely due to reradiation of stellar emission intercepted by orbiting dust grains. We have identified a large sample of main-sequence stars with possible excess IR radiation by cross-correlating the Michigan Catalog of Two-dimensional Spectral Types for the HD Stars with the IRAS Faint Source Survey Catalog. Some 60 of these Vega-like sources were not found during previous surveys of the IRAS database, the majority of which employed the lower sensitivity Point Source Catalog. Here, we provide details of our search strategy, together with a preliminary examination of the full sample of Vega-like sources.1998ApJ...497..330Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/497/330CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/156 : IRAS Faint Source Catalog, |b| > 10, Version 2.0 (Moshir+ 1989)III/31 : Michigan catalogue for the HD stars, vol. 1 (Houk+, 1975)III/51 : Michigan Catalogue of HD stars, Vol.2 (Houk, 1978)III/80 : Michigan Catalogue of HD stars, Vol.3 (Houk, 1982)III/133 : Michigan Catalogue of HD stars, Vol.4 (Houk+, 1988)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/497/330https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/497/330http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/497/330https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/497/330https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/497/330http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/497/330GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/ApJ/497/330/table2Newly identified candidate main-sequence stars with debris disksSpTypeSpectral typesrc.spTypecharNameObject namemeta.idcharrecnoRecord number assigned by the VizieR team.
