Suppose an astronomer detects an object that displays jets of material shooting out of opposite sides. This object is probably NOT

C) a neutron star in a binary system.
D) a supermassive black hole.

Quizplus · Accepted Answer

Jets of material are typically associated with objects that have accretion disks, where material from a surrounding medium or companion star is drawn in. Solitary black holes (without a companion star or significant surrounding material to form an accretion disk) are not expected to produce jets, as there is no material to be ejected. In contrast, black holes in binary systems, neutron stars in binary systems, and supermassive black holes often have accretion disks from which jets can be launched.
