| Abstract: |
Low-mass X-ray binaries (LMXBs) are systems in which a low-mass
companion transfers mass via Roche-lobe overflow onto a black hole
(BH) or a weakly magnetized neutron star (NS). There are two key
differences between NSs and BHs – presence/absence of a solid
surface and the (dipole) magnetic field. It is believed that both
the solid surface and the magnetic field can affect the accretion
flow and show some observable effects. Comparing the disk
evolution of the two types of systems, we find that different
phenomena exist below 10% Eddington luminosities, while the same
evolution pattern is shared above the critical ones. We discuss
the implications of the results on theoretical models. |
