Disk galaxies, like our own Milky Way galaxy, commonly consist of both a thick and thin disk of stars—each with different features, including stellar population and movement. Three major theoretical ...

This article examines the spectroscopic properties of young stellar objects, linking accretion dynamics to observed ...

Astronomers used RR Lyrae stars to trace the early Milky Way, revealing a rapid formation of its halo and disk, with chemical patterns similar to Andromeda.

The figures illustrate the revealed sequential disk formation in this study: thick disk only galaxies dominate the early epochs (bottom panel), while galaxies exhibiting both thin and thick disks ...
