Formation of flattened planetesimals by gravitational collapse of rotating pebble clouds

S Lorek, A Johansen - Astronomy & Astrophysics, 2024 - aanda.org
Planetesimals are believed to form by the gravitational collapse of aerodynamically
concentrated clumps of pebbles. Many properties of the objects in the cold classical Kuiper …

Higher order heat fluxes in a rarefied granular gas

A Hong, A Morris - Physics of Fluids, 2022 - pubs.aip.org
Despite its general application, the Fourier's law of heat conduction is not always valid in
dilute gases. One of the physical shortcomings of Fourier's law is the mismatch at the …
