Spectropolarimetry and wind asymmetries of Wolf-Rayet stars
Symposium - International astronomical union
Motivated by the question of what drives the winds of Wolf-Rayet (WR) stars, I have been investigating the structure of WR winds. Observational evidence has been accumulated which demonstrates that the winds of some (but not all) WR stars are not spherically symmetric or homogeneous. I review results of work in the literature pertaining to the detection of such wind asymmetries in single WR stars and WR binary components. Particular emphasis is placed on the technique of spectropolarimetry, anddoi:10.1017/s0074180900201939 fatcat:ji6cfmljpvg2hlywm6hq5c4sou
