The Case of the Missing Giants
Red giant stars are bright enough to see at the center of our galaxy, but they are missing. A new study puts stars in a wind tunnel to explore a possible way to dim the lights.
The tempestuous adolescence of circumstellar disks
Massive gas inflow can trigger disks around young stars to become gravitationally unstable, resulting in vigorous accretion onto the star.
After Super-Earth (Formation)
Will Smith and his son Kitai are back in this highly anticipated, totally unexpected sequel and this time, they’ve crash landed on a Super-Earth. Surviving won’t be easy, but it might be even harder for the planet’s atmosphere.
The Dwarf that Devours Planets
Astronomers may have finally observed the event that explains polluted white dwarfs and their debris disks.
Ripping Apart Asteroids to Account for Earth’s Strangeness
Earth’s composition seemingly does not fit into planet formation theory. Ripping apart its building blocks by collisions during accretion might sound violent, but can be a way to go.
Triggered fragmentation in self-gravitating disks
How to form clumps in the intermediate ranges of massive protoplanetary disks? Could these later be planets?
