A Sandwich Model for Changing-look Active Galactic Nuclei

The Astrophysical Journal
The spectral variability of changing-look active galactic nuclei (CL-AGNs) occurred on timescales of years to tens of years, posing a significant challenge to the standard thin disk model. In this work, we propose a sandwich model, including an optically

Detailed Radial Scale Height Profile of Dust Grains as Probed by Dust Self-scattering in HL Tau

The Astrophysical Journal Letters
The vertical settling of dust grains in a circumstellar disk, characterized by their scale height, is a pivotal process in the formation of planets. This study offers in-depth analysis and modeling of the radial scale height profile of dust grains in the

INFLUENCE OF CRITICAL PARAMETRES OF THICK-STALK CROP CHOPPER ON POWER

Advanced Engineering Research, 2011
The constructive circuit design of the rotational disk shredder designed to chop thick-stalk crops is presented. Some computational formulas for power consumption in fixed and free shredding are offered.
