A non-accreting and non-beaming neutron star in a close binary is discovered and characterized by modelling the observed periodic variabilities in the visible companion star. This neutron star belongs to an abundant but less-explored population that cannot be seen with popular techniques such as X-ray and gamma-ray observations.
