Millisecond pulsars (MSPs) are evolved neutron stars with short spin periods that have gone through a long period of mass transfer in a low-mass X-ray binary phase. Globular clusters (GCs)—conglomerations of tens of thousands ...

Most of what we know about the universe comes from studies on stars, and about half of the stars are found to be in binary systems. The close binary interaction between the stellar components may change the destiny of the ...

The first ever exoplanets were discovered 30 years ago around a rapidly rotating star, called a pulsar. Now, astronomers have revealed that these planets may be incredibly rare. The new work will be presented tomorrow (Tuesday ...

Using NASA's Fermi space telescope, Chinese astronomers have investigated a newly discovered millisecond pulsar known as PSR J1835−3259B. As a result, they identified gamma-ray pulsations from this source. The finding is ...
More than 50 years after the discovery of the first pulsar, the detailed physics of the emission process in a pulsar magnetosphere still remains unclear.
