Multicolor Polarimetry of Selected BE Stars: 1995-1998
Abstract
A new polarimeter called AnyPol has been used at Limber Observatory for 4 yr to monitor annually the broadband linear polarization of a sample of bright northern Be stars. This is the fourth report on a program started in 1985 at McDonald Observatory and the first one to come entirely from the new installation. Although no variability was detected at the 3 sigma level during the current reporting period, analysis of the full 13 yr data set is beginning to reveal hints of long-term variability that may provide clues for understanding the Be phenomenon.
