Resonance accretion on the magnetized rotating neutron star
It is suggested that the accretion disk excites the eigen modes of Alfven oscillations of the magnetic field tubes the ends of which are frozen to the neutron star surface. The resonance takes place when the eigen Alfven frequency coincides with the difference of the Keplerian disk rotation frequency and the frequency of rotation of a neutron star. This model explains the two narrow lines of QP...
متن کاملAccretion onto the neutron star in Be/X-ray binaries
We study accretion onto the neutron star in Be/X-ray binaries, using a 3D SPH code and the data imported from a high resolution simulation by Okazaki et al. (2002) for a coplanar system with a short period (Porb = 24.3 d) and moderate eccentricity (e = 0.34). We find that a timedependent accretion disk is formed around the neutron star in Be/X-ray binaries. The disk shrinks after the periastron...
متن کاملOn the warping of Be star discs
The theory of radiatively-induced warps in accretion discs is applied to the discs of Be stars. It is found that these discs may develop warps in their inner regions, although once the warp amplitude is large enough then the interaction between the disc and fast radiatively-driven wind will determine its evolution. The warping is shown to be more important for later than earlier B stars. Althou...
متن کاملHot Radiative Accretion onto a Spinning Neutron Star
A new type of self-similar hot viscous radiative accretion flow onto a rapidly spinning neutron star has recently been discovered. This “hot brake” flow forms in the two-temperature zone (close to a central object), but at a sufficiently low accretion rate and a high spin it may extend in the radial direction beyond ∼ 300 Schwarzchild radii into a one-temperature zone. When the spin of the star...
متن کاملImpact of Hadronic Axions on Black Hole Accretion Discs and Neutron Stars
iii Acknowledgment I am greatly indebted to my supervisor, Georg Raffelt, for introducing me to this intriguing subject, and for his support and advice. Furthermore, I have benefited from the friendly and stimulating atmosphere at the Max-Planck-Institut für Physik, München. Thanks to all the students and postdocs, especially to Robert Buras for stimulating discussions, and Maurice Lausberg and...
