cds-question@unistra.frearly-type-starsultraviolet-astronomyinterstellar-mediumextinctionWe have discovered ultraviolet (UV) halos extending as far as 5{deg} around four (of six) bright UV stars using data from the Galaxy Evolution Explorer satellite. These halos are due to scattering of the starlight from nearby thin, foreground dust clouds. We have placed limits of 0.58+/-0.12 and 0.72+/-0.06 on the phase function asymmetry factor (g) in the FUV (1521{AA}) and NUV (2320{AA}) bands, respectively. We suggest that these halos are a common feature around bright stars and may be used to explore the scattering function of interstellar grains at small angles.2011ApJ...734...13Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/734/13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/312 : GALEX-DR5 (GR5) sources from AIS and MIS (Bianchi+ 2011)VI/110 : Final Merged Log of IUE Observations (NASA-ESA, 2000)III/188 : IUE Atlas of B-Type Stellar Spectra (Walborn+ 1995)III/86 : SKYLAB S-019 Far-UV Objective-Prism Spectrophotometry (Henize+ 1979)II/59 : Catalogue of stellar UV fluxes (TD1) (Thompson+ 1978)III/77 : Copernicus 0.2-A Resolution Far-UV Stellar Spectra (Snow+ 1977)J/A+A/545/A130 : alpha Eri differential phases (Domiciano de Souza+, 2012)J/ApJS/187/149 : StarCAT: STIS UV echelle spectra of stars (Ayres, 2010)J/ApJS/126/461 : Equivalent Widths in the Spectrum of Sirius (Zhao+, 2000)J/A+AS/105/305 : OB stars observed with high dispersion by IUE (Bohlin+ 1994)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/734/13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/734/13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/734/13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/734/13https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/734/13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/734/13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/734/13/table3 (GALEX FUV and NUV data around stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/734/13/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/734/13/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/734/13/table3?GETtext/xml+votable180.050000true199.6969-10.97850.005555555555555556Cone search capability for table J/ApJ/734/13/table1 (Observation log)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/734/13/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/734/13/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/734/13/table1?GETtext/xml+votable180.050000true201.2982472-11.16131940.0055555555555555563/310 4/1220 1221 1223 1228 1230 1231 1232 1234 1235 1253 1264 1600 1601 1602 1606 1608 1611 1612 2087 2091 2093 2104 2177 2181 2183 2188 5/4871 4877 4879 4888 4890 4900 4901 4903 4908 4909 4911 4918 4934 4976 4978 4984 5008 5009 5011 5060 5061 5143 5150 5171 5172 5174 5175 5177 5180 5183 5186 5187 5218 5219 5221 5222 5224 5226 5268 5269 5271 5313 5314 5318 5319 5323 5324 6231 6237 6239 6261 6263 6412 6413 6416 6418 6419 6428 6430 6438 6439 6440 6441 6443 6452 6454 6456 6457 6458 6460 8346 8347 8359 8368 8369 8370 8376 8377 8378 8380 8381 8383 8394 8422 8424 8425 8428 8717 8719 8720 8722 8723 8729 8731 8741 8743 8749 8756 8757 8758 8760 8771 8776 8778 9913 9914 9915 6/18158 18159 18170 18171 18174 18175 18346 19479 19483 19504 19505 19514 19515 19557 19558 19559 19564 19565 19566 19609 19611 19641 19664 19665 19666 19668 19669 19676 19678 19730 19740 19742 19810 19816 19818 19819 19944 19946 19988 19989 19991 20040 20041 20043 20069 20080 20081 20084 20085 20087 20248 20249 20250 20252 20256 20257 20260 20261 20288 20545 20561 20562 20563 20566 20567 20569 20571 20589 20594 20595 20604 20606 20677 20678 20679 20692 20694 20695 20716 20717 20724 20726 20727 20728 20729 20739 20742 20769 20772 20773 20774 20784 20798 20799 20864 20866 20867 20870 20871 20882 20892 20894 20902 20903 20908 20909 20910 20915 20930 20940 21080 21081 21082 21108 21109 21250 21251 21260 21261 21263 21266 21280 21281 21282 21284 21286 21287 21291 21300 21302 21303 21304 21305 21306 21308 24917 24919 24945 24947 24953 24955 25041 25043 25049 25077 25656 25659 25661 25663 25668 25670 25671 25688 25724 25726 25744 25746 25747 25749 25750 25751 25769 25812 25814 25820 25822 25836 25837 25838 25848 26129 26132 26133 26176 33343 33379 33381 33382 33383 33429 33430 33431 33433 33435 33455 33484 33485 33486 33516 33518 33529 33570 33571 33574 33580 33582 33583 33680 33682 33704 33706 33709 33720 33721 33723 34821 34864 34865 34867 34873 34875 34884 34886 34912 34913 34922 34923 34961 34963 34969 34971 34993 35036 35044 35045 35046 35072 35074 35080 35089 35090 35096 35098 35108 35109 35110 35116 35200 39629 39630 39631 39634 39635 39640 39641 39642 39651 39664 39666 39667 39672 39674 39853 44715 44718 44719 44729 44730 44731 44734 44735 44778 44779https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/734/13?format=asciiUVdefaultJ/ApJ/734/13/table3GALEX FUV and NUV data around starsE(B-V)E(B-V)magphot.color.excessfloatrecnoRecord number assigned by the VizieR team.
