Blue vampire Star caught sucking Red Giant s gas

The mechanics of stellar vampirism, however, proved less dramatic than astronomers anticipated. They expected to see hot gas funneling from a cool red giant star into a hot, dense blue star. Instead they saw mostly nothing.

The binary star system, called SS Leporis, likely uses a lesser-known method to send gas from one star to the other.

“For a long time this system was suspected as a typical example of star vampirism, but it’s more light and friendly than we would have loved to see,” said astronomer Jean-Philippe Berger of the European Southern Observatory and co-author of an upcoming study on SS Leporis in Astronomy & Astrophysics.

Binary systems contain two stars orbiting a common center of mass. If the stars orbit close enough to each other, they can share gas to become “symbiotic binaries” like SS Leporis, which is located about 910 light-years from Earth.
