Simulated Gravity Field Estimation for the Main Belt Comet 133P/Elst-Pizarro Based on a Satellite-to-satellite Tracking Mode
《Research in Astronomy and Astrophysics》2023年第9期129-141,共13页Shang-Biao Sun Jian-Guo Yan Wu-Tong Gao Bo Wang Zhen Wang Mao Ye Jean-Pierre Barriot 
supported by the National Natural Science Foundation of China (42241116 and U1831132);supported by the Macao Science and Technology Development Fund (No. SKL-LPS(MUST)-20212023);the 2022 Project of Xinjiang Uygur Autonomous Region of China for Heaven Lake Talent Program;supported by the Chinese Academy of Sciences Foundation of the young scholars of western (2020-XBQNXZ-019);supported by a DAR grant in planetology from the French Space Agency (CNES).
Most asteroids and comets are formed in the early stages of the solar system and therefore contain a wealth of information about their birth.The asteroid exploration mission planned in the coming years by China will l...

The Evolution of the Nucleus Surface in the Context of the Change in the Brightness of a Comet
《Research in Astronomy and Astrophysics》2022年第5期136-145,共10页Marcin Wesolowski 
the Centre for Innovation and Transfer of Natural Sciences and Engineering Knowledge, University of Rzeszów, Poland
The paper presents a model of the thermodynamic evolution of the comet nucleus surface.In the proposed approach,we focus on the analysis of the formation of pits visible on the surface of the cometary nucleus.These pi...

Thermodynamic model of the activity of the comet 103P/Hartley
《Research in Astronomy and Astrophysics》2021年第12期297-304,共8页Marcin Wesolowski 
The paper presents three processes related to the dynamics of cometary particles.The following thermodynamic mechanisms were taken into account:quiet sublimation,emission of cometary matter via jet and migration of pa...

The role of astronomical silicates during a cometary outburst被引量：1
《Research in Astronomy and Astrophysics》2021年第3期184-192,共9页Marcin Wesołowski 
the support the author received from the Centre for Innovation and Transfer of Natural Sciences and Engineering Knowledge,University of Rzeszow,Poland。
This paper presents a new approach to analyzing the change of cometary brightness.In our considerations,we assume that astronomical silicates(dust agglomerates)and gas are present in the coma.This assumption is a cons...

Thermodynamic model of comet 29P/SW brightness changing
《Research in Astronomy and Astrophysics》2020年第8期298-306,共9页Marcin Wesotowski 
the author received from the Centre for Innovation and Transfer of Natural Sciences and Engineering Knowledge,University of Rzeszow,Poland。
We analyze the thermodynamic model of changes in comet brightness focusing on the exceptional case which is comet 29 P/Schwassmann-Wachmann(hereafter 29 P/SW).This object demonstrates quasiregular flares that occur in...
