They were then captured by the smaller companion star
The gravitational effects from the hot and super dense white dwarf are so strong that it has forced the companion star
to swell up like a massive balloon and move towards it.
Astronomers believe the companion star
took most of the hydrogen surrounding the exploding main star and continued to burn as a super-hot helium star.
That, in addition to the star system's young age, has led to two possible theories: either a neutron star can be born with a weak magnetic field, or it can quickly become de-magnetized as it pulls material from its companion star
Because the planet is relatively close to its own sun, the gravity from the companion star
doesn't affect it much.
In work published in The Astrophysical Journal, the Monash and Warwick scientists significantly improved the precision with which they could measure the orbit of Scorpius X-1, a double star system containing a neutron star that feeds off a nearby companion star
5 ( ANI ): X-rays streaming towards Earth from the region near a neutron star that is cannibalizing its companion star
are the youngest "X-ray binary" yet known, according to scientists.
A nova erupts when a white dwarf, the burned-out core of a sun-like star, has siphoned off enough hydrogen from a companion star
to trigger a thermonuclear runaway.
Scientists already know of other supernova remnants that contain black holes, like SS433, a binary system composed of a black hole that is producing huge jets of gas, and a companion star
that's 20 times the mass of our Sun.
These first observations revealed that the pulsar was spinning more than 30 times each second and was gravitationally bound to a companion star
, which was initially identified as either another neutron star or, more likely, an uncommonly cool white dwarf.
org, match astronomers' ideas about what would be left if a blue straggler took gas from a now-defunct companion star
This star's capricious behavior appears to be fueled by a nearby companion star
and may give new insights into the birth of millisecond pulsars, the astronomers said.
