HD 38282 (R144, BAT99-118, Brey 89) is a massive, hydrogen-rich Wolf-Rayet Star in the Tarantula Nebula (Large Magellanic Cloud).
Star have been suspected to be binaries by previous studies (Schnurr et al. 2008b). As to R144, however, the combined data sets are not sufficient to find any periodicity.[3]

- ↑ Probable binary, with detected X-ray emission presumed to come from colliding winds. The luminosity of the individual components would obviously be less than quoted here, both because there will be multiple fainter stars, and because the combination of spectra can lead to unexpectedly high estimates of the total luminosity. Confirmed as a spectroscopic binary by Sana et al, 2013.
