[vsnet-chat 3861] KR Mus

KR Mus

   I noticed that KR Mus is classified as a planetary nebula in some
references.  The variable star designation was given from the supposed
classification as an eclipsing variable from Hipparcos photometry.
Is this a rare "eclipsing PN nucleus" or of a different type?
