Astronomy of the invisible
- September 2003 article from
Physics World, by
Giovanni F. Bignami. "Neutron stars might be the dimmest
objects in the universe but they are also cosmic laboratories
for extreme physics that are tailor-made for X-ray and gamma-ray
Strongest magnet in the cosmos
- January 2003 article from
Physics World, by
Silvia Zane and Roberto Turolla.
"Now an international team of astrophysicists studying the RXTE
data has found evidence for what is known as a magnetar -- the
most magnetic object in the universe."
Pulsars, glitches and superfluids
- January 1998 article from
Physics World, by
M. Ali Alpar. "Astronomers have long been intrigued by occasional
"glitches" in the rotation of pulsars."

- March 12, 2003 press release on important new observations
of the Crab Nebula pulsar.
Nucleus sheds light on neutron stars
- June 2001 news article from
"A neutron star may be around 10 kilometres in diameter, but it
is governed by the same forces that arrange the neutrons in an
atomic nucleus just femtometres across. This means that studies
of neutron-rich nuclei could provide insights into their
The pulsar's powerhouse
- December 2000 news article from
"Astronomers believe that highly magnetic neutron stars - known
as magnetars - could be the driving force behind a
little-understood group of pulsars. 'Anomalous x-ray pulsars',
as they are known, earn their name because scientists are unsure
what fuels their potent x-ray emissions."
Wobbling pulsar discovered
- August 2000 news article from
"Astronomers at Jodrell Bank Observatory in the UK have
discovered a wobbling pulsar for the first time."
Slow period upsets pulsar theories
- August 1999 news article from
"Australian astronomers have discovered a radio pulsar with a
period so long that they might have to rethink theories of
how pulsars emit radiation."
Fast spinning pulsar
- January 1998 news article from
"Astronomers have discovered the fastest-spinning pulsar. The
star rotates at speeds previously thought impossible."

Scientific American, February 2003
- Let There Be Spin
Science News, July 13, 2002, pp. 24-25
- It has been a puzzle how very rapidly rotating neutron stars
acquire their angular momentum. The answer may be that the spin
results from the star's gradual consumption of mass from a
