Written in the Stars: the Moment our Galaxy Began Boiling
Today’s authors use stellar chemistry and kinematics to identify the moment our Milky Way cooked up its disk.
The Giant Bubble Driving Nearly All Nearby Star Formation
We’ve known for some time that we reside in the Local Bubble, a cavity of low-density gas excavated by an orchestra of dying stars ~15 Myrs ago. Today’s authors find that this Bubble’s expansion is driving nearly all nearby star formation.
Hey, you’ve got some planet stuck in your teeth…
Take a bite out of today’s post, where the authors explore the occurrence rate of planetary ingestion in wide binary stellar systems. Turns out that about a fourth of Sun-like stars in wide binaries may ingest their planetary companions. Yum!
Peering Inside the Galactic Archaeology Toolbox
Ever wanted to take a peak into a Galactic archaeologist’s toolbox? Today’s authors take us on a great tour of theirs as they investigate several moving groups discovered pre-Gaia that may be part of the Milky Way halo!
Keeping Time in the Milky Way with Chemical Clocks
Stellar ages are notoriously difficult to determine. However, today’s authors investigate a promising new method of estimating stellar age with “chemical clocks!”
