Woman Who Discovered Pulsars to Speak at Texas Tech

Dame Jocelyn Bell Burnell was a doctoral student when she found the first evidence of pulsars, a type of neutron star.

WHAT: Dame Jocelyn Bell Burnell, an astrophysicist, will speak on "The Discovery of Pulsars." It is free and open to the public and should be accessible to the general audience. No special scientific knowledge is necessary.

Pulsars are a type of neutron star. Neutron stars are the dense, dead remnants of massive stars and have masses a little larger than the sun's inside a region about the same size as Loop 289 around Lubbock.

WHEN: 5:30 p.m. Friday (March 27)

WHERE: Room 007, Science Building (northwest of Chemistry Building)

WHO: Burnell, who grew up in Northern Ireland and earned her bachelor's degree from the University of Glasgow, was a doctoral student tracking quasars at the University of Cambridge when she noticed signals that were becoming brighter and fainter with a regular interval between the bright pulses, which could not be quasars. Further studies from Burnell and other scientists identified these objects as pulsars.
