High-Mass X-Ray Binaries with Be Donors as Ultraluminous X-Ray Sources
Shigeyuki Karino
Since the detection of X-ray pulses from ultraluminous X-ray sources (ULXs) in 2014, neutron stars have been considered as their central objects. However, it remains unclear how ne…
Spin evolution of neutron stars in wind-fed high mass X-ray binaries
Shigeyuki Karino
The observed X-ray pulse period of OB-type high-mass X-ray binary (HMXB) pulsars are typically longer than 100 seconds. It is considered that the interaction between the strong mag…
Stellar wind accretion and accretion disk formation: applications to neutron star high mass X-ray binaries
Shigeyuki Karino, Kenji Nakamura, Ali Taani
Recent X-ray observations have revealed the complexity and diversity of high-mass X-ray binaries (HMXBs). This diversity challenges a classical understanding of the accretion proce…
On the possibility of disk-fed formation in supergiant high-mass X-ray binaries
Ali Taani, Shigeyuki Karino, Liming Song +3
We have considered the existence of neutron star magnetic field given by the cyclotron lines. We collected the data of 9 sources of high-mass X-ray binaries with supergiant compani…
Determination of wind-fed model parameters of neutron stars in high-mass X-ray binaries
Ali Taani, Shigeyuki Karino, Liming Song +2
We have studied several neutron star high-mass X-ray binaries (HMXBs) with super-giant (SG) companions using a wind-fed binary model associated with the magnetic field. By using th…
Nature of donors in ultra-luminous X-ray binaries powered by neutron stars
Shigeyuki Karino
In this study, we examine the properties of donor stars of the three recently discovered ultraluminous X-ray sources (ULXs) powered by rotating neutron stars. For this purpose, we…
