| I read up on interstellar objects and astrophysics and studied quasars, pulsars and supernovas, but my main focus was black holes. |
| In theory, pulsars could remain intact at speeds as high as 1,000 to 3,000 revolutions per second. |
| For that reason, such objects are called pulsars, and they have provided our best data about neutron stars. |
| They do not come much littler than pulsars, which despite weighing about as much as the sun are a mere ten kilometres in diameter. |
| That pulsars are part of a binary system is indicated by Doppler shifts in the pulse period and the change in arrival time of the pulse. |
| All in all he quintupled the number of known pulsars in that particular sector of the sky. |
