Thin disk - Wikipedia
The thin disk is a structural component of spiral and S0-type galaxies, composed of stars, gas and dust. It is the main non-centre (e.g. galactic bulge) density, of such matter.

Galactic Thin Disk
Of the components of our MILKY WAY GALAXY, the thin disk is the most prominent part to our eyes. It manifests itself as the band of faint light that we see encircling the whole sky.
Galactic disc - Wikipedia
A galactic disc (or galactic disk) is a component of disc galaxies, such as spiral galaxies like the Milky Way and lenticular galaxies. Galactic discs consist of a stellar component (composed of most of the galaxy's stars) and a gaseous component (mostly composed of cool gas and dust).

25.1: The Architecture of the Galaxy - Physics LibreTexts
2022年4月11日 · The brightest part of the Galaxy consists of a thin, circular, rotating disk of stars distributed across a region about 100,000 light-years in diameter and about 1000 light-years thick. (Given how thin the disk is, perhaps a CD is a more appropriate analogy than a wheel.)
Milky Way's thin disk is billions of years older than we thought
2024年8月1日 · Scientists discovered ancient stars in the Milky Way's thin disk, some over 13 billion years old, challenging old galaxy formation timelines.
Within a thin disk approximation some quantities are functions of radius only: j(r), Ω(r), e(r), while others are function of radius and time: Σ(r,t), M˙ (r,t), J˙(r,t), E˙(r,t), F(r,t), g(r,t). Taking this into account the equations (d1.15), (d1.16), (d1.17) may be transformed into 2πr ∂Σ ∂t + ∂M˙ ∂r = 0, (d1.18) M˙ dj dr ...
Recent studies of the kinematics and ages of disk stars of our Galaxy have revealed the presence of two distinct populations in the Galactic disk, called the thick and the thin disk popula-tions.
Galactic Thin Disk | Structure, Formation & Dynamics
2024年5月28日 · Explore the structure, formation, and dynamics of the Milky Way's galactic thin disk, including its chemical composition and the impact of stellar migration and spiral arms.
Thin Disk | COSMOS - Swinburne
The thin disk is the defining component of disk galaxies in general and spiral galaxies in particular. It contains stars, star clusters, gas and dust which are confined to the galaxy’s plane of rotation.
