Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team led by Prof. HAN Jinlin from National Astronomical Observatories of Chinese Academy of Sciences (NAOC) has discovered 201 pulsars, including many very faint pulsars, 40 millisecond pulsars (MSPs), and 16 pulsars in binaries.
These discoveries were published in
Pulsars are compact remnants of the death of bright, massive stars. They have the strongest magnetic field, highest density and fastest rotation of any celestial body in the Universe, and show significant relativistic effects in systems of binary compact stars.
Since the first pulsars were discovered in 1968, about 3,000 pulsars have been found in total. Among them, about 400 have a period less than 30 milliseconds and are very stable in rotation.

BEIJING, May 20 (Xinhua) Using China s Five-hundred-meter Aperture Spherical radio Telescope (FAST), scientists have discovered 201 pulsars, including faint pulsars and millisecond pulsars.
The research was led by the National Astronomical Observatories (NAOC) under the Chinese Academy of Sciences. The findings were published in the journal Research in Astronomy and Astrophysics on Thursday.
Pulsars, or fast-spinning neutron stars, originate from the imploded cores of massive dying stars through supernova explosions.
They have the strongest magnetic fields, the highest density, and the fastest rotation of any celestial body in the universe and are thus an ideal laboratory for studying the laws of physics in extreme environments, said Han Jinlin with the NAOC, leader of the research.
