Continuum optical circular polarisation in the young O star θ¹ OrionisC?

MOFFAT A.F.J. and EVERSBERG T.

Abstract (from CDS):

Recently, Donati & Wade (1999A&A...341..216D) have claimed rather spectacular, large, variable circular polarisation in the optical continuum of Θ¹ Orionis C, obtained with the echelle spectropolarimeter MuSiCoS. However, based on experience with the William-Wehlau spectropolarimeter, a similar unit using two fiber feeds, we suggest that this is the spurious result of instrumental effects. We propose a remedy to eliminate the effect.
