Latest Binary pulsar Stories
In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed.
Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary system that contain rapidly spinning neutron stars, also known as pulsars.
Scientists using NASA's Swift and Chandra X-ray Observatory say they have discovered a millisecond pulsar with a dual identity.
An international team of scientists led by astronomer Adam Deller (ASTRON) have used the Very Long Baseline Array (VLBA) to set a new distance accuracy record, pegging a pulsar called PSR J2222-0137 at 871.4 light-years from Earth.
Pulsars are one of the most baffling classes of astronomical objects. Originally discovered as flickering sources of radio waves, pulsars were soon interpreted as rapidly rotating and strongly magnetized neutron stars about the size of a small city.
Scientists at the Max Planck Institute have discovered a millisecond pulsar accompanied by an unusual sub-stellar partner known as a "black widow."
Pulsars, superdense neutron stars, are perhaps the most extraordinary physics laboratories in the Universe. Research on these extreme and exotic objects already has produced two Nobel Prizes.
NASA said on Thursday that its scientists have discovered a surprisingly powerful millisecond pulsar that challenges existing theories.
An international team of astronomers has discovered an exotic planet that appears to be made of diamond orbiting a tiny star in our galaxy.
