- Year Discovered: 1995
- Location: Found Throughout Universe
One of the freakiest things NASA discovered is certainly the existence of vampire stars. They get their name honestly, as one star manages to suck the energy away from another. Usually, this involves a binary star system where usually one white dwarf star is primary and a second mass transferring star is secondary. The stars are incredibly close to one another, causing gravity from the white dwarf to distort the secondary star. The white dwarf is accreting matter from its companion.
This companion star is often called a “donor star” as it’s giving itself to the white dwarf. The infalling matter is rich in hydrogen too, only helping the dwarf star’s energy. An accretion disk is formed, where strong UV and X-Ray emissions are present. The companion star eventually loses gravitational energy. Usually, the white dwarf gets what it needs, but it can suck up too much from its companion and reach a Type Ia supernova. This is all so vampire-like that it’s scary.
