cds-question@unistra.frwolf-rayet-starsinfrared-photometryextinctionvariable-starsmilky-way-galaxymagellanic-cloudsPhotometry at 3.4 and 4.6{mu}m of 128 Population I WC type Wolf-Rayet stars in the Galaxy and 12 in the Large Magellanic Cloud (LMC) observed in the WISE NEOWISE-R survey was searched for evidence of circumstellar dust emission and its variation. Infrared spectral energy distributions (SEDs) were assembled, making use of archival r, i, Z, and Y photometry to determine reddening and stellar wind levels for the WC stars found in recent IR surveys and lacking optical photometry. From their SEDs, 10 apparently non-variable stars were newly identified as dust makers, including three, WR 102-22, WR 110-10, and WR 124-10, having subtype earlier than WC8-9, the first such stars to show this phenomenon. The 11 stars found to show variable dust emission include six new episodic dust makers, WR 47c, WR 75-11, WR 91-1, WR 122-14, and WR 125-1 in the Galaxy and HD 38030 in the LMC. Of previously known dust makers, NEOWISE-R photometry of WR 19 captured its rise to maximum in 2018 confirming the 10.1-yr period, that of WR 125 the beginning of a new episode of dust formation suggesting a period near 28.3yr. while that of HD 36402 covered almost a whole period and forced revision of it to 5.1yr.2019MNRAS.488.1282Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/488/1282CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/488/1282https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/488/1282http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/488/1282https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/488/1282https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/488/1282http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/488/1282GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/488/1282/table1 (Galactic program stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/488/1282/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/488/1282/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/488/1282/table1?GETtext/xml+votable180.050000true40.298647256.73048190.005555555555555556Cone search capability for table J/MNRAS/488/1282/table2 (Large Magellanic Cloud program stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/488/1282/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/488/1282/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/488/1282/table2?GETtext/xml+votable180.050000true74.0120547-69.45598530.005555555555555556Cone search capability for table J/MNRAS/488/1282/table19 (Properties of WR stars showing variation in their dust emission, including orbital information or indications of possible binarity)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/488/1282/table19?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/488/1282/table19?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/488/1282/table19?GETtext/xml+votable180.050000true154.5207856-58.27395690.0055555555555555566/3231 3272 3758 12970 14072 14264 14453 14640 14666 14692 14788 17368 19672 24150-24151 27106 28809 28824 28826 28912 29095 29114 29505 29532 30219 30222 30244-30245 30258-30259 30262 30264-30265 30310 30312 30318-30319 30594 30607 30622 30666 30690-30692 30694 30706 30713 32085 33052-33053 33076 33091 33094 33100-33101 33112 33122 33126 37246 37349 37364 37882 37901 37923-37924 37928 38017 38019 39709 41570 41654-41655 41657 41671 41680 41683-41685 41688 41698 41758 41794 41805 41811 42159 42167 42170 42213-42217 42223 42225-42227 42236 42295 42371 42379 42440-42441 42444 42459 42497 42512 43014 43018-43019 430751.6553710307751707e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/488/1282?format=asciiInfrareddefaultJ/MNRAS/488/1282/table1Galactic program starsSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
