Abstract
Longitudinal oscillations in hot post-flare coronal loops are studied in the nonlinear hydrodynamic approximation. To explain its rapid damping, the mechanism of thermal conductivity, important at high temperatures, is used. In the case of large amplitude, numerical simulations show that nonlinearity inhibits damping.
Supporting agencies: The study was carried out according to the state assignment of the Ministry of Education and Science of the Russian Federation (No. 075-03-2023-121/3 "Development of new observational and theoretical approaches in space weather forecasting based on ground-based observations").
