Asteroids torn by white dwarfs fragment into kilometer-sized chunks, not dust

Study findings published: kilometer-size barrier limits tidal fragmentation

1 Oct 29 6:50 PM · 9d ago · 2 articles · 1 post · 3 sources · development 1 of 1

Research reveals that rubble-pile asteroids retain internal strength from Van der Waals forces, leaving most debris mass in pieces 0.1 to 1 kilometer in size rather than dust, requiring additional collisions or processes to break apart further.

“Understanding the details of how debris around white dwarfs is produced and evolves is important for putting the observations into context.”
