Are Symbiotic and Vampire Stars the same type of star or different?
As the title of the research paper linked to in the ESO press release is "An incisive look at the symbiotic star SS Leporis", it is safe to conclude that they are the same type of star. My suspicion is that, since symbiotic stars transfer and accrete mass via either Roche-lobe overflow or stellar wind overflow, the term "vampire star" was coined as part of the press release as a "cute" way to imply that one star is "feeding" on another.
