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.
A star located about 1,300 light-years from Earth shows signs of having devoured one of its planets — and is now gearing up for a second helping, according to a pair of new stud ...
In 5 billion years or so, the sun will expand into a Red Giant and completely consume the Earth. For the first time ever, scientists have witnessed this very process, called planetary engulfment, in a ...
xAs tragic as it sounds, the engulfment of a planetary object by its stellar parent is a common scenario throughout the Universe. But it doesn’t have to end in doom. A team of astrophysicists has used ...
Negative regulation of glial engulfment activity by Draper terminates glial responses to axon injury
Neuronal injury elicits potent cellular responses from glia, but molecular pathways modulating glial activation, phagocytic function and termination of reactive responses remain poorly defined. Here ...
When our sun exhausts the hydrogen fuel in its core some 5 billion years from now, it will expand to become a red giant, engulfing the inner planets. The dynamics and possible outcomes of planetary ...

A new study using hydrodynamical simulations reveals the forces acting on a planet when it is swallowed by an expanding star. The results show that the interactions of a substellar body (a planet or ...
