Using TESS data to nd exoplanets-research of some conrmed exoplanets, focusing on the methods

Abstract

In this paper, we present some light curves and schematic diagrams related to our methods. The data released from TESS are our basic resources for finding exoplanets. Exoplanets may exist inside both single stellar system and multi-stellar systems. We will present 4 planets according to our findings. However, we first carefully chose 2 binary systems from a catalog of 4584 eclipsing binaries to give a fundamental analysis through details in the light curves. Then comes the ways of detecting exoplanets inside extrasolar systems, mainly transit, radial velocity (or Doppler method) and microlensing. The methods also yield some of the properties of the exoplanets, such as their orbital period, mass, radius, etc. Finally, we will talk about both the advantages and disadvantages of our methods, and with some future improvements. We use python to help us visualize the data observed in the light spectrum, and the code will be placed in the last part of this paper.
