Programm 11. November

When neutron stars collide: cataclysms in space

On 11 November, PhD student Stephanie Brown tells us about the cataclysmic collision of neutron stars.

The collision of two neutron stars is bright enough to be seen millions of light-years away, and the blast sends ripples through the very fabric of spacetime itself that we can detect here on earth.

Darum geht's

Neutron stars are some of the most extreme objects in the universe. Though they are approximately one-and-a- half times the mass of our sun, they are less than 30km across. With magnetic fields that are often more than 100 million times that of the earth's as well as surface gravitational fields 200 billion times stronger than earth's, they are fascinating objects on their own. Now imagine that two of them collide! The resulting cataclysm is not only bright enough to be seen millions of light-years away, but the blast sends ripples through the very fabric of spacetime itself that we can detect here on earth. Stephanie Brown will be explaining what neutron stars are, where they come from, and what exactly happens when they collide.
