WebApr 26, 2024 · In the standard accretion scenario of magnetized neutron star (e.g. Davidson 1973; Gnedin & Sunyaev 1973; Basko & Sunyaev 1976), at low accretion rates, the free-falling flow is stopped by nucleon collisions at the surface of the neutron star, and X-ray radiation is emitted in a pencil beam along the magnetic pole; above a critical … WebAbstract: Although we are nearing a consensus that most ultraluminous X-ray sources (ULXs) below 10 41 erg s −1 represent stellar mass black holes accreting in a super-Eddington ‘ultraluminous’ accretion state, little is yet established of the physics of this extreme accretion mode. Here, we use a combined X-ray spectral and timing analysis of …
WebWe construct Super-Eddington Slim Disks models around both stellar and super-massive black holes by allowing the formation of a porous layer with a reduced effective opacity. We show that at high accretion rates, the inner part of the disks become radiation pressure dominated. However, unlike the standard scenario in which the disks become thick, … Webtion of such high accretion rates. The slim disk model (Abramowicz et al. 1980, 1988) is often used to describe accretion disks in this regime, and there have recently been a number of numerical simulations to study the properties of super-Eddington accretion disks (Ohsuga et al. 2005; Jiang et al. 2014a; McKinney et al. 2014;Sa̧dowski et al ...
