Abstract
Finding the mass-boundary that divides Fully and Partially convective stars can prove to be very useful in understanding the properties exhibited by these different types of stars, most importantly the role of the Tachocline, which is the boundary in Low Mass Stars that divides the convective and radiative regions of a star. Here, we analyzed data from NASA's Transiting Exoplanet Survey Satellite (TESS) survey, focusing primarily on M-dwarfs present in TESS Sectors 1 and 2, to determine this mass-boundary. The two distinguishing observables for fully and partially convective stars that we used in our analysis are the Relative Flare Energy and the Spot Filling Factor. Furthermore, this analysis can be expanded to the other sectors as well to get more extensive results regarding the position of the mass-boundary.
