Animations show the evolution of density and flow in simulations of a planet embedded in the envelope of a giant star, showing the interactions of the inspiralling planet with the gas in its vicinity.

The world's most elaborate cosmological simulation of the evolution of our universe was recently completed by astrophysicists. For the first time, a hydrodynamic cosmological simulation is large ...

Astrophysicists have confirmed the accuracy of an analytical model that can unlock key information about supermassive black holes and the stars they engulf. At the center of most large galaxies lives ...

At the center of most large galaxies lives a supermassive black hole (SMBH). The Milky Way has Sagittarius A*, a mostly dormant SMBH whose mass is around 4.3 million times that of the sun. But if you ...

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 ...

A snapshot from a hydrodynamical simulation of a three-solar-mass star, which shows gravity waves generated by turbulent core convection propagating throughout the star's interior. Gravity waves in ...
