A Search for Hot Subdwarf Companions to Rapidly-Rotating Early B Stars
Abstract
We continue to search for O-type subdwarf companions in binary systems containing Be primaries. We were not able to confirm an sdO object in π Aqr and HR 2142, even though optical and UV observations suggest their presence. Some possible reasons are enumerated.
