Understanding the surprising narrowness of eccentric debris belts
Some extrasolar debris belts are not just eccentric but also surprisingly narrow. What processes can influence the width of debris belts?
Aluminum in Action: Are Rockier Exoplanets More Common than We Think?
It is theorized that the radioactive decay of Aluminum-26 could provide enough heat to dehydrate terrestrial planetesimals as they form, leading to rockier exoplanets. But is this effect significant enough to alter how common we believe rocky exoplanets are in the Galaxy? Find out by reading today’s bite!
The Ghosts of Planets Past: Determining the Composition of Planetary Remnants
How can studying white dwarfs help us understand the composition of planets? Find out in today’s guest post!
Aeolian-erosion in protoplanetary disks
Being a planetesimal ain’t easy. But sometimes to make it big you have to first get broken down.
Edge-on disks: Nothing dust it better.
Today’s astrobite explores edge-on disks that can provide insight into how dust is transported in protoplanetary disks.
Moonetesimals likely form relatively quickly
The absence of dusty circumplanetary disks around young giant planets suggests moonetesimals grow relatively quickly.
