Analysis on Gliese 486 b

Abstract

Gliese 486 b, also known as GJ 486 b, is an exoplanet orbiting around a red dwarf near our solar system. The celestial body is fair target for TESS to observe and related data of it have been collected by TESS. This paper firstly focuses on methods used to obtain planetary parameters and the theoretical base behind them. Then, it turns to some further calculation with our best-fit data, and analogy to the methods that previous researches used. Finally, the paper introduces analysis on the changing period and the relevant potential causes. The paper concludes with some discussion on directions of future investigations.
