On the other hand, no companion star
was found for the Type Ia supernova SN 2011fe in the nearby galaxy M101.
Our knowledge of a binary evolution suggests that, if the companion star
can survive the transition, brown dwarfs should be common in this type of system.
Additionally the companion star
at ~16 magnitude puts this within reach of many amateur telescopes which can then contribute valuable data.
A team of astronomers have now spotted a black hole companion star
with too many heavy elements.

Or one white dwarf could siphon gas off a companion star
until the white dwarf gains so much mass that it blows up.
Gas can then flow from the companion star
to the neutron star or black hole, producing spectacular displays when some of the material is blasted out in powerful jets at close to the speed of light," he says.
Using NASA s Hubble Space Telescope, astronomers have discovered a companion star
to a rare type of supernova.
These systems consist of pairs of objects where a compact star, either a neutron star or, more rarely, a black hole, is capturing material from an orbiting companion star
WASHINGTON (CyHAN)- Astronomers have found evidence for a companion star
that survived the blast of a supernova explosion.
Are they caused by a white dwarf pulling so much material from a companion star
that it becomes unstable and explodes, or do they result from the merger of two white dwarfs?
The horse was runner-up two months ago to stable companion Star
