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!”
Chemical tagging without chemical abundances? Today’s authors devise a neural network that ‘disentangles’ chemical abundances from stellar spectra to avoid the uncertainties that often beset chemical taggers.
The search for the elusive intermediate-mass black hole continues. Today’s authors present a novel method to search for Milky Way intermediate-mass black holes with the hyper-velocity stars they eject!
