Eclipsing pulsar promises clues to crushed matter
— 18 Aug 2010 07:38 | AstronomyAstronomers using NASA's Rossi X-ray Timing Explorer (RXTE) have found the first fast X-ray pulsar to be eclipsed by its companion star. Further studies of this unique stellar system…
RXTE homes in on a black hole's jets
— 2 Jul 2010 10:47 | AstronomyFor decades, X-ray astronomers have studied the complex behaviour of binary systems pairing a normal star with a black hole. In these systems, gas from the normal star streams toward…
Nearby black hole is feeble and unpredictable
