On the origin of super-global spin-up trends of X-ray pulsars in HMXB systems
Vitaliy Kim, Yerlan Aimuratov
Most X-ray pulsars in high-mass X-ray binary (HMXB) systems exhibit both global and local trends of spin acceleration (spin-up) and deceleration (spin-down). Moreover, decades-long…

Stellar wind parameters of massive stars in accretion-powered High Mass X-ray Binary Pulsars
N. Beskrovnaya, N. Ikhsanov, V. Kim
The process of mass-exchange between the components of High Mass X-ray Binary (HMXB) systems with neutron stars undergoing wind-fed accretion is discussed. The X-ray luminosity of…
