All stars, including the sun, have a finite lifetime. Stars shine by the process of nuclear fusion in which lighter atoms, such as hydrogen, fuse together to create heavier ones. This process releases vast quantities of energy ...

Indian astronomers have employed NASA's NuSTAR spacecraft to inspect an X-ray pulsar known as 1E 1145.1-6141. Results of the observations deliver important insights into the properties and nature of this pulsar. The study ...
Pulsar signals obtained with radio telescopes are extremely weak. Generally, there are two primary difficulties in pulsar signal processing—one is the radio-frequency interference (RFI) mitigation, and the other one is ...

Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME), astronomers have detected a new radio pulsar in a binary system with a massive non-degenerate companion star. The discovery of the pulsar, which received designation ...
Through giant lobes of gamma radiation, an international team of researchers have found a small satellite galaxy of the Milky Way filled with dark matter, but whose emissions are more likely the result of millisecond pulsars ...

Using the Large Phased Array (LPA) radio telescope of Pushchino Radio Astronomy Observatory (PRAO) in Russia, astronomers have detected seven new pulsars and determined their basic parameters. The finding is reported in a ...
Using the Neutron Star Interior Composition Explorer (NICER), an international team of astronomers have detected a new accreting millisecond X-ray pulsar. The newfound pulsar, designated MAXI J1816–195, has a spin period ...
