@ebortey could you please find a definition of super-Eddington accretion from an authoritative source?

I found this explanation:
“the rate required would need to exceed the Eddington limit. This is the point at which the outward force produced by radiation pressure is equal to the gravitational attraction experienced by the in-falling matter. In principle, this implies that there is a maximum luminosity an object of mass M can emit; assuming spherical accretion and that the opacity is dominated by Thompson scattering, this Eddington luminosity is LE=1.38×10³⁸(M/M⊙) erg s^-1.”

Possibly a definition for the Eddington limit could be added, here's one I found, but it's quite long:
"The theoretical upper limit of luminosity at which the radiation pressure of a light-emitting body would exceed the body's gravitational attraction. A star emitting radiation at greater than the Eddington limit would break up. The Eddington luminosity for a non-rotating star is expressed as: L_Edd = 4πGMm_pcσ_T^-1, where G is the gravitational constant, M the star mass, mp the proton mass, c the speed of light, and σT the Thomson cross section. It can also be written as LEdd = 4πGMcκ^-1, where κ is the opacity. In terms of solar mass, the Eddington limit can be expressed by: L_Edd = 1.26 × 10³⁸ (M/Msun) erg s^-1"

@BartlettAstro would you be able to look over these definitions to ensure they're accurate?
