NASA Watching a Volatile Stellar Relationship

In biology, “symbiosis” refers to two organisms that live close to and interact with one another. Astronomers have long studied a class of stars – called symbiotic stars – that co-exist in a similar way. Astronomers are gaining a better understanding of how volatile this close stellar relationship can be. via NASA http://www.nasa.gov/mission_pages/chandra/images/watching-a-volatile-stellar-relationship.html
