| Description |
Pulsars are neutron stars, objects so extreme that they pack, in a sphere of diameter smaller than Sydney about half a million times the mass of the Earth. Some of these objects (the so-called ``Millisecond Pulsars'') can spin hundreds of times per second, and do so with extreme regularity, like very precise clocks. They manage to remain together because, at their surfaces the gravitational forces are about 1 million million times stronger than at the Earth's surface. Over the last 15 years, our team has discovered 23 of these very exotic objects in the globular cluster 47 Tucanae using the Parkes telescope. We keep studying them to find out how they are moving in the sky (this will tell us something about the gravitational force of the cluster), and to measure precisely how they are moving in their orbits around their companion stars. We might even find a planet orbiting one of them! |
