Title: Study on the Thermal Evolution of Near-Earth S-type Asteroids
Abstract: Most near-Earth objects are thought to originate from the collisional fragments of the main asteroid belt. One question that remains to be resolved is the proportion of near-Earth objects sampling the core area material of the parent body to the outer layers. In this talk, I will introduce our recent work to investigate whether the surfaces of a series of S-type near-Earth asteroids have undergone significant thermal metamorphism (high petrologic type). Our results show that the surface materials of most LL chondrite near-Earth asteroids have a high petrologic grade. Most LL chondrite near-Earth asteroids may originate primarily from the core area of the main belt parent body or bodies.
Speaker Bio: Dr. Pengyue Wang received his PhD degree at Macau University of Science and Technology. He has worked as a postdoctoral research fellow at Macau University of Science and Technology since 2024. His research primarily focuses on the small bodies in the solar system. He utilizes both spectral modeling and observational data analysis to investigate the composition and evolution of small bodies.
