# What does LC mean?

LC can mean Light Cylinder.

#### Explanation:

A light cylinder is a theoretical cylinder around a pulsar which is a rapidly spinning neutron star.

The radius of the cylinder is:
$r = \frac{c P}{2 \pi}$
Where c is the speed of light and P is the period of the neutron star.

If an object on the surface of the cylinder were to rotate at the same angular velocity as the neutron star it would have to be travelling at the speed of light.
