The Age–Velocity Dispersion Relations of the Galactic Disk as Revealed by the LAMOST-Gaia Red Clump Stars

The Astrophysical Journal
Using nearly 230,000 red clump stars selected from LAMOST and Gaia, we conduct a comprehensive analysis of the stellar age–velocity dispersion relations (AVRs) for various disk populations, within 5.0 ≤ R ≤ 15.0 kpc and ∣ Z ∣ ≤ 3.0 kpc.

Winds and Disk Turbulence Exert Equal Torques on Thick Magnetically Arrested Disks

The Astrophysical Journal
The conventional accretion disk lore is that magnetized turbulence is the principal angular momentum transport process that drives accretion. However, when dynamically important large-scale magnetic fields thread an accretion disk, they can produce mass ...

Magnetic Activity in Thick Accretion Disks and Associated Observable Phenomena: II. Flux Storage

, 1993
In paper I, we have studied the conditions under which flux tubes are expelled from adiabatic thick accretion disks. In the present paper, we explore a few other models of thick disks, where flux tubes could be stored.

Comparison of magnetized thick disks around black holes and boson stars

European Physical Journal C: Particles and Fields
Boson stars are considered as promising candidates for black hole mimickers. Similar to other compact objects they can form accretion disks around them.

Topology optimization of disk–shaft rotating body under thermomechanical coupling

Case Studies in Thermal Engineering
Turbine rotors often operate under harsh conditions, such as high rotational speeds and large temperature gradients, that requires them to withstand complex thermal and centrifugal loads.
