18. The compression of neutrons in the contracting core
20. Two bodies which are close enough that their gravitational attraction causes them to orbit each other

1. a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.
2. a circular motion which acts along the radius and is directed away from the centre of the circle
