[[File:Wr137 spc.png|thumb|left|upright=1.0|WR 137的光譜顯示電離碳和氦突出的發射線。]]

'''WR 137'''位於[[天鵝座]]，是一顆距離[[地球]]大約6,000光年的[[沃爾夫-拉葉星]][[變星]]。
WR 137與[[WR 134]]和[[WR 135]]是1867年在[[天鵝座]]觀測到的3顆光譜在連續的譜帶中有強烈的[[發射線]]，而不是常見的[[吸收線]]組成。它們是天文學家[[夏爾·沃爾夫|沃夫]]和[[若爾日·拉葉|瑞葉]]發現的第一批外觀不尋常，並以發現著的名字命名的[[沃爾夫-拉葉星]]<ref>{{cite book|doi=10.1888/0333750888/4101|chapter=Wolf, Charles J E (1827-1918)|title=The Encyclopedia of Astronomy and Astrophysics|pages=4101|date=2001|isbn=0333750888|bibcode=2000eaa..bookE4101.|author1=Murdin|first1=P.}}</ref>。它是碳序列的沃夫-瑞葉星，表明缺乏氮的譜線而有強的碳發射譜線射。WR 137光譜的CIII發射比CIV微弱，OV也微弱，因此它的光譜型為WC7。它的頻譜還顯示HeII和OIV的譜線<ref>{{cite journal|bibcode=1966ApJ...143..770H|title=Spectral Classification of Wolf-Rayet Stars|url=https://archive.org/details/sim_astrophysical-journal_1966-03_143_3/page/n163|journal=Astrophysical Journal|volume=143|pages=770|author1=Hiltner|first1=W. A.|last2=Schild|first2=R. E.|year=1966|doi=10.1086/148556}}</ref><ref name=sander/>。

WR 137是[[聯星]]系統，伴星O9的[[主序星]]或[[巨星]]。這兩顆星在一個相對扁平的橢圓軌道上互繞，軌道週期為13年。在[[拱點|近星點]]附近似乎產生了一個塵埃雲。軌道的傾斜度不確定，很可能在67°附近，氮一些分析的建議值在23°左右<ref name=lefevre/>。O型星在視覺上更亮，質量也更大，但WR星主導了光譜，具有更高的輻射熱發光度（熱光度）。

WR 137距離WR135大約1度，兩者被認為都在天鵝座OB3星協內，且與地球有大致相同的距離<ref name=gervais>{{cite journal|bibcode=1999AJ....118.2394G|title=A Large H I Shell surrounding the Wolf-Rayet Star HD 191765|url=https://archive.org/details/sim_astronomical-journal_1999-11_118_5/page/2394|journal=The Astronomical Journal|volume=118|issue=5|pages=2394|author1=Gervais|first1=Simon|last2=St-Louis|first2=Nicole|year=1999|doi=10.1086/301065|doi-access=free}}</ref>。因為存在熱發光伴侶，使它的屬性不確定。組合光譜的偽擬合產生56,000K的溫度，光度為{{solar luminosity|537,000}}，半徑為{{solar radius|10}}。典型WC7型的半徑是{{solar radius|4.5}}，這意味著溫度要更熱<ref name=lefevre/>。
