A dense ring of the trans-Neptunian object Quaoar

2023.4.19  The dense rings of the giant planets1, as well as Chariklo2 and Haumea3 lie within the Roche limit of the central bodies, assuming ρ=400 kg m−3, typical of the small inner saturnian satellites21. With this value, Quaoar’s classical Roche limit is near 1,780 km, much smaller than the ring radius of 4,100 km (Table 1 and Extended Data Fig. 2).

Opacity limit for supermassive black hole seeds - arXiv

2022.4.23  The argument above operates with fundamental limits to the cooling ability of gas, set by thermodynamics. Next, we will gain further insight by considering the detailed physics of H opacity, based on the actual microphysical cross sec-tion for this process. To this extent, we use a one-zone model for the collapse of gas into an atomic cooling halo.

Roche Limit - an overview ScienceDirect Topics

III.A The Roche Surface. The key element in binary star evolution is the role of the Roche limit, which was first introduced in the three-body problem. It is known in the celestial mechanics literature as a zero-velocity surface, but we will treat it as the bounding equipotential for a self-gravitating star:
