Study Reveals Distant Activity of Long-Period Comet Tsuchinshan–ATLAS
By conducting systematic observations of the long-period comet C/2023 A3 (Tsuchinshan–ATLAS), a recent study reveals, for the first time, the activity enhancement process of this comet at large heliocentric distances (from 7.2 au to 5.9 au). The findings provide observational evidence for understanding the activity mechanisms and evolutionary patterns of long-period comets at large heliocentric distances.
