Today’s authors use stellar chemistry and kinematics to identify the moment our Milky Way cooked up its disk.
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.
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!
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!
Stellar ages are notoriously difficult to determine. However, today’s authors investigate a promising new method of estimating stellar age with “chemical clocks!”
