WUPPE

OBJECT: VELA X-1

UW Astronomer: Geoff Fox

The only target in this program which was observed was Vela X-1 = HD77581. Since any intrinsic polarization effects appeared to be small, the observations made were analyzed along with the other stars in the WUPPE interstellar medium polarization program. See our paper in AJ 112, 2726 1996.
