Study Notes
Jocelyn Bell Burnell
- Born in Belfast, Northern Ireland.
- Recognized physics was easy while at boarding school.
- Resolved to work in astronomy as a teenager.
- Graduated from Glasgow University in 1965.
- Began a PhD thesis at Cambridge University on twinkling quasars.
- Detected pulsars while a postgraduate student, opening a new branch of astrophysics.
- Worked under Antony Hewish, helping to design and build radio telescopes to detect quasars.
- In November 1967, instruments detected radio waves pulsating every 1.337 seconds from a fixed point in space.
- Determined that the radio waves came from the radiation beam of a rapidly rotating, strongly magnetized neutron star.
- Each rotation emitted a "pulse", giving the name "pulsar" to the new class of star.
- Playfully named the suspiciously precise radio waves LGM-1 (Little Green Men-1) until the term "pulsar" was coined in 1968.
- Antony Hewish reported her discovery in a Nature article in 1968.
- Her supervisor received the Nobel Prize in Physics in 1974, but she was not named in the award.
- Made a Dame Commander of the British Empire (DBE) in 2007 for her services to astronomy.
