Definition Stellar accretion refers to the inflow of ambient gas onto the surface of a star. During the process of star formation, accretion builds up the object to its final mass. The infalling gas is the interior portion of adense core, a smallmolecular cloudthat collapses under the influen...

This implies an upper limit of 10−4 M⊕ to 10−2 M⊕ of late accretion on each planet since the dispersal of the system’s gaseous disk. This is comparable to (or less than) the late accretion on Earth after the Moon-forming impact4,5, and demonstrates that the growth of the...
The detection1 of a dust disk around the white dwarf star G29-38 and transits from debris orbiting the white dwarf WD 1145+017 (ref. 2) confirmed that the photospheric trace metals found in many white dwarfs3 arise from the accretion of tidally disrupted
The problem of disk accretion onto the surface of a neutron star with a weak magnetic field at a luminosity exceeding several percent of the Eddington one is reduced to the problem of the braking of a hypersonic flow with a velocity that is 0.4–0.5 of the speed of light above the base ...
