Lunch talk on Feb. 20, 2023

Compact objects--white dwarfs, neutron stars, and black holes--are "born" when normal stars "die"


Speaker:Jianwei Zhang (NAOC)

Venue:SWIFAR Building 2111

Time:12:30 PM, Monday, Feb. 20, 2023

Abstract:

In astronomy, a compact star (sometimes called a compact object) is a star that is a white dwarf (WD), a neutron star (NS) or a black hole (BH). In general, they are remnants of stellar explosions with extremely high densities and strong magnetic fields, making them relevant for a variety of unusual high-energy astrophysical phenomena such as gravitational waves (GWs), high energy X-ray/gamma-ray radiation, and fast radio bursts (FRBs). Therefore, they can be used as unique cosmic laboratories for testing the theories on gravitation and astrophysics under extreme conditions, such as general relativity (GR). In this talk, we will provide a general background of astronomical compact objects and review our statistical researches on the mass of NSs and BHs of LIGO-Virgo GW sources, the magnetic field distribution of normal pulsars, and the distribution of FRB dispersion measures.
