¡°What if normal baryonic matter
is compressed so tightly that atomic nuclei come in to close contact?¡± (An
introduction to the problem I am focusing on during the summer camp for
excellent undergraduates, held in the school of physics at Peking University,
July 12, 2021)
Let's listen to the Vela pulsar (the sound of Vela) in radio band ... You are also invited going to the page of Pular Group at PKU.
the former develops in hadron degrees of freedom, while the latter is relevant to quark degrees (and especially with the strangeness). Can we find hard observational evidence to rule out that pulsars are neutron stars or strangeon stars? This is certainly one of the big questions in the coming years, maybe the first one to be solved in the era of gravitational-wave astronomy.

I am teaching three courses these years, two (Astrophysics & Atomic physics) for undergraduates and one (Physics of compact stars) for graduates. The book "Introduction to Astrophysics" was written during my teaching of astrophysics.
