PREFACE This is a summary of the paper _The Milky Way Has No Distinct Thick Disk_ by . Traditionally the stars within the disks of spiral galaxies are considered to form two distinct populations. One population, termed the “thin disk”, is generally comprised of young and metal-rich stars while the other population of older and more metal-poor stars make up the “thick disk”. The paper from challenges this assumption of bi-modality within the Galactic disk and argue for a “continuous and monotonic scale-height distritbution”.
