cds-question@unistra.frinfrared-photometrymultiple-starsIn this paper, we present a catalog that includes 141 bright candidates (<=10.27mag, V band) showing an excess of infrared (IR) at 22{mu}m. Of these 141 candidates, 38 stars are known IR-excess stars or disks, 23 stars are double or multiple stars, and 4 are Be stars while the remaining more than 70 stars are identified as 22 {mu}m excess candidates in our work. The criterion for selecting candidates is K_s_-[22]_{mu}m_. All these candidates are selected from the Wide-field Infrared Survey Explorer all-sky data cross-correlated with the Hipparcos main catalog and the likelihood-ratio technique is employed. Considering the effect of background, we introduce the IRAS 100{mu}m level to exclude the high background. We also estimate the coincidence probability of these sources. In addition, we present the optical to mid-IR spectral energy distributions and optical images for all the candidates, and give the observed optical spectra of six stars with the National Astronomical Observatories, Chinese Academy of Sciences' 2.16m telescope. To measure for the amount of dust around each star, the fractional luminosity is also provided. We also test whether our method of selecting IR-excess stars can be used to search for extra-solar planets; we cross-match our catalog with known IR-excess stars with planets but found no matches. Finally, we give the fraction of stars showing excess IR for different spectral types of main-sequence stars.2013ApJS..208...29Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/208/29CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/311 : WISE All-Sky Data Release (Cutri+ 2012)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)J/MNRAS/426/91 : Kepler stars with infrared excess emission (Kennedy+, 2012)J/AJ/134/26 : Binaries with white dwarf in 2MASS (Hoard+, 2007)J/ApJ/660/1556 : Characterization of dusty debris disks (Rhee+, 2007)J/ApJ/653/675 : Spitzer 24{mu}m photometry of A dwarfs (Su+, 2006)J/ApJ/586/1356 : White dwarfs with cool companions (Wachter+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/208/29https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/208/29http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/208/29https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/208/29https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/208/29http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/208/29GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/208/29/table3 (Stars with 22um excess)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/208/29/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/208/29/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/208/29/table3?GETtext/xml+votable180.050000true0.9348847-17.335970.0055555555555555566/1219 1628 1731 2170 2259 2317 2336 2370 4189 4277 4338 4597 4755 5044 5645 6085 6390 6512 6583 7332 7561 8366 8743 8790 9105 9331 9565 9714 9762 9778 9836 9901 10124 10367 10472 11079 11419 11424 11469 11553 11662 11959 11970 12126 12548 15291 16019 16543 16606 17158 17421 17887 18064 18187 18455 18494 18660 18737 18957 18970 18981 19192 19509 19567 19598 19651 19935 20482 20515 20530 20581 20612 20642 20657 20658 20695 21008 21043 21083 21161 22636 23007 23538 24277 25119 25564 25713 26145 26494 27118 27735 28018 28150 31436 31472 31507 32651 33508 33582 33694 33943 34046 34096 34161 34164 34244 34257 34304 34409 34415 34460 34490 34493 34683 34754 35293 35327 35815 35896 36130 36351 37011 38671 38917 40239 40242 40319 44981 45253 45975 46081 47027 47205 47338 47389 47717 48541 48844 489308.650015785639275e-20 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/208/29?format=asciiInfrareddefaultJ/ApJS/208/29/table3Stars with 22um excessImag[3.8/8.3] Johnson I band magnitudemagphot.mag;em.opt.Ifloate_Imag[0/0.2] Uncertainty in Imagmagstat.error;phot.mag;em.opt.Ifloate_Ksmag[0.01/0.3] Uncertainty in Ksmagmagstat.error;phot.mag;em.IR.KfloatrecnoRecord number assigned by the VizieR team.
