First Constraining Upper Limits on Gravitational-wave Emission from NS 1987A

While the neutron star presumably formed in SN 1987A has never been observed directly, x-ray observations indicate the presence of a young pulsar wind nebula. Such a young neutron star could emit continuous gravitational waves through a variety of mechanisms. If emitting at a level detectable by LIGO, the star is spinning down very quickly, complicating searches for gravitational waves. I describe recent searches which found no astrophysical signal but set the first physically constraining upper limits on gravitational waves from NS 1987A.
