Gravity causes matter to clump together, forming everything from stars to planets. Accretion disks form when material swirls around a central object due to conserved angular momentum. Magnetic fields ...

A research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with other researchers, has developed a new method to estimate how stellar-mass compact objects ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...
