Recently, Professor Wang Xinmingfrom School of Physics, Xidian University, has made new progress in the study of the evolution of the original planetary disk, with two relatedsingle-author papers published inThe Astrophysical Journal, a topinternational journal in the field of astronomy and astrophysics.

In this study, Mr. Wang Xinming extended the traditional one-dimensional original planetary disk density evolution equation that has been used for decades to a new evolution equation group.A large-scale numerical calculation program has been proposedforefficient equation solving with success in the solution ofmany numerical problems.The research was supported by the NSFC and International cooperation platform.

The "protoplanetary disk" is a dusty gas disk surrounding a young star.The disk contains all the materials needed toform planets. Under the influenceof static electricity and gravity, the matter in the protoplanetary disk keeps converging and finally forms a planet.

The study of the protoplanetary disk belongs to the category of astrophysics, which is an important branch of physics. Astrophysicsresearch is an important engine for the development of basic disciplines. In recent years, the Nobel Prize in Physics has been awarded to astrophysicists many times. While deepening our understanding of the universe, astrophysics promotes the birth of many new technologies in the process of exploration. Therefore, astrophysics is not only "high in the sky", but also down to earth,bringingmeaningfulchange to and even fundamental transformation ofour life.

Profile of Wang Xinming

From 2002 to 2011, he studied at Jilin University, whereheobtained his B.S., M.S. and Ph.D. of Science degrees.Since 2011, he has been withthe School of Physics of XidianUniversity, lecturing on College Physics and Electromagnetics.
