Roche limit of stars

WebThe roche limit is a calculation of when pieces of a satellite will be pulled off the satellite. Any force that affects the whole satellite equally can be ignored, as this will affect the motion of the satellite as a whole but not (directly) whether pieces are pulled off. WebAs the ratio of the density of the larger object to the smaller object approaches 1, the Roche limit approaches 1.26 times the radius of the larger object. Neutron stars also have a …

In celestial mechanics, the Roche limit, also called Roche radius, is the distance from a celestial body within which a second celestial body, held together only by its own force of gravity, will disintegrate because the first body's tidal forces exceed the second body's self-gravitation. Inside the Roche limit, orbiting … See more The Roche limit typically applies to a satellite's disintegrating due to tidal forces induced by its primary, the body around which it orbits. Parts of the satellite that are closer to the primary are attracted more strongly by … See more The limiting distance to which a satellite can approach without breaking up depends on the rigidity of the satellite.

If we suppose that the star plunges when its orbital radius reaches 6 Rg, the maximum black hole mass for there to be mass transfer from a ∼0.3 M ⊙ dwarf star is 1.6–1.9 × 10 7 M ⊙ ( kω = 0 − 1).

WebAnswer: Neutron star dimensions aren’t usually expressed in square miles; that sounds like a surface area.
