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 … 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, …

[email protected] The Eddington luminosity, also referred to as the Eddington limit, is the maximum luminosity a body (such as a star) can achieve when there is balance between the force of radiation acting outward and the gravitational force acting inward. The state of balance is called hydrostatic equilibrium. When a star … See more The limit is obtained by setting the outward radiation pressure equal to the inward gravitational force. Both forces decrease by inverse square laws, so once equality is reached, the hydrodynamic flow is the same throughout … See more The role of the Eddington limit in today's research lies in explaining the very high mass loss rates seen in for example the series of outbursts of η Carinae in 1840–1860. The … See more Observations of massive stars show a clear upper limit to their luminosity, termed the Humphreys–Davidson limit after the researchers who first wrote about it. Only highly unstable … See more • Surpassing the Eddington Limit. See more The Eddington limit is not a strict limit on the luminosity of a stellar object. The limit does not consider several potentially important factors, and super-Eddington objects have been observed that do not seem to have the predicted high mass-loss rate. Other … See more • Hayashi limit • List of most massive stars See more clublied rc lens

WebSuper-Eddington accretion has been shown, through numerical models, to generate powerful bipolar jets, which become active as the accretion rate exceeds the Eddington rate. These jets, though highly collimated, have the potential to shut off the very accretion flow that is driving the jets, and regulate the accretion flow to values sub ...
