外文摘要：We have chosen the Large Scale Atomic/Molecular Massively Parallel Simulator(LAMMPS)code to calculate the coalescence of silicon carbide(SiC),silicon oxide dust(SiO)in the AGB stellar wind.LAMMPS is a classical molecular dynamics simulation code.At the same time,we consider the effect of temperature on the evolution of molecular dynamics.We also calculated the temperature change of non-spherical SiC,SiO dust coalescence.The condensation temperature range of SiC dust in the AGB stellar wind is[300-500]k and[900-1100]k for SiO.Finally,the infrared spectrum of SiC was calculated using Gaussian 16 software.The 77SiC,70Si3C3,and 121Si3C3 models have clear characteristic peaks of infrared spectra responding at 5,8.6,11.3,15,19,and 37 μm.
