Death of Stars - Astronomy @ Walton High School

It orbits so fast it is hot enough to give off x-rays which we can measure. The black hole forces such a gravitational force on these ...

At this mass the gravitational force of the sink particle is strong enough to pull gas towards it with velocites sufficiently high to heat the gas to a maximum temperature of ∼ 7,000K. Th ...
