An international team of astronomers using a state-of-the-art receiver system on the 305-m Arecibo radio telescope in Puerto Rico has discovered a binary pulsar system which promises to be an ...

An illustration of the 14 pairs of binary pulsars used to measure our galactic acceleration. In a new study just published here in early 2021, the orbital periods and changes in the orbital periods of ...

The pulsar is often compared to lighthouses because it emits beams of electromagnetic radiation that are pointed toward specific directions. A binary pulsar is a twin-star system made of a pulsar and ...

Researchers from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) and their collaborators at home and abroad have discovered a binary pulsar with a 53-minute orbital ...

Using the data obtained by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team led by Prof. PAN Zhichen and Prof. LI Di from the National Astronomical Observatories of ...

Pulsars are incredible heavenly bodies. They are neutron stars just 20 kilometers (12 miles) in diameter that pack more mass than our Sun. Their defining characteristic though is the beam of radio ...

The general theory of relativity is a remarkably successful model for gravity. However, many of the best tests for it don't push its limits: they measure phenomena where gravity is relatively weak.

An international team of astronomers has spotted a binary pulsar that appears to behave very differently than most known binary systems in our galaxy. The most likely explanation, says the team, is ...

Rare star system This is the first time that a short-life binary consisting of a neutron star and a helium star has been detected. (Courtesy: Bureau of International Cooperation, Chinese Academy of ...

Figure 1: The three-dimensional orientation of the pulsar orbit is determined using a classical geometric model. The orbital inclination parameterizes the shape of the Shapiro delay, that is, the ...
