Gas kinetic theory provides the fundamental framework for understanding the behaviour of gases from the molecular scale to macroscopic flow phenomena. Recent developments in simulation methods have ...

It’s difficult to predict with certainty what will happen when giant stars collide, but new, first-of-their-kind hydrodynamic simulations by the DEMOBLACK team at the University of Padova in Italy ...

step forward in the understanding of processes of collision at such scales. It plays an essential part in estimating the energy of the impact which should be necessary, depending on its size, to ...

Planet-forming disks start out as a mix of dust and gas, but the gas doesn’t stick around for long. As the star at their center ignites, the radiation it emits starts driving off the gas, eventually ...
