HD 151932

HD 151932, also known as WR 78, is a Wolf-Rayet star located in the constellation Scorpius, close to the galactic plane.

[10] Despite being a blue-colored Wolf-Rayet star, it is extremely reddened by interstellar extinction, so its apparent magnitude is brighter for longer-wavelength passbands.

Like most extremely massive stars, HD 151932 is losing mass via its stellar wind.

[11] A periodic shift in the spectrum with a period of 3.3 days (implying it is a spectroscopic binary) has been noticed, but it may be spurious; the star appears to be a single star but may be orbiting face-on and/or with a lower-mass companion.

[8] Related to this is the fact that the Si IV line varies irregularly in radial velocity, the nature of which is largely unknown.

WR 78 lies directly west of NGC 6231 , with the reddish ζ 2 Scorpii to the south
