2. More details on the Robinson Lecture by Jocelyn Bell Burnell:
ARMAGH OBSERVATORY 2004 ROBINSON LECTURE
The 2004 Robinson Lecture will be held on Friday, 26th November at 7.30 p.m.
in The Studio Theatre, The Market Place, Armagh. The Robinson Lecture is held
biennially in memory of the founder of the Armagh Observatory, Archbishop
Richard Robinson. The guest Lecturer is Professor Jocelyn Bell Burnell, former
Dean of Science at the University of Bath and now Visiting Professor at the
University of Oxford. The lecture is entitled "Tick, Tick, Tick Pulsating Star, How
We Wonder What You Are!"
Born in Northern Ireland, Professor Bell Burnell graduated in 1965 with a
B.Sc. in Physics from the University of Glasgow, followed by a Ph.D. in Radio
Astronomy from the University of Cambridge in 1969. While working as a research
student on quasars, Jocelyn discovered a wholly new type of celestial object --
pulsars -- with the 4.5-acre radio telescope that she helped to construct. In
the months following this initial discovery, Jocelyn went on to find three
more of these pulsating radio sources, which were later identified as neutron
stars rotating at up to a few hundred times per second. The discovery of pulsars
was contained in an appendix to her doctoral thesis.
"Pulsars are some of the most amazing objects in the Galaxy," commented Prof
Bell Burnell, "And their discovery took the astronomical community by
surprise. Like lighthouses in the sky they may be used one day as navigation beacons
for interstellar travel. They have stretched our understanding of the behaviour
of matter, and serve as very accurate clocks with which to check out
Einstein's theory of relativity."
Professor Bell Burnell will outline the discovery and characteristics of
pulsars in a non-technical manner and bring us right up to date with current
research on these puzzling objects. A typical pulsar contains slightly more matter
than the Sun within a sphere of radius 10km. These weird neutron stars have
extreme electrical, magnetic and gravitational fields. Some pulsars have even
been discovered to have planetary-sized bodies orbiting them, but why this
should be so -- considering that pulsars are believed to be born from catastrophic
supernova explosions -- remains an enigma.
Jocelyn held the post of Professor of Physics at the Open University from
1991 until 1999 and was subsequently Dean of Science at the University of Bath
until Sep 2004. She is also the immediate past President of the Royal
Astronomical Society. Professor Antony Hewish, Jocelyn's Ph.D. supervisor, received a
half share in the 1974 Nobel Prize for Physics for his role in the discovery of
pulsars. The late Fred Hoyle argued that Jocelyn should have received a share
of the Prize.
