Evidence for neutron star triaxial free precession in Her X-1 from Fermi/GBM pulse period measurements
Dmitry Kolesnikov, Nikolai Shakura, Konstantin Postnov
Her X-1/HZ Her is one of the best studied accreting X-ray pulsars. In addition to the pulsating and orbital periods, the X-ray and optical light curves of the source exhibit an alm…
