Discovery of a 693.5 S Period in the X-ray Binary 4u 1820−30: a Superhump Interpretation
The X-ray source 4U 1820-30 in the globular cluster NGC 6624 is known as the most compact binary among the identified X-ray binaries (XRBs). Having an orbital period of 685.0 s, the source consists of a neutron star (NS) primary and likely a 0.06-0.08 M [subscript ☉] white dwarf (WD) secondary. Here...
