Light curves, radius and mass of the exoplanets of my different constelations

HAT-P-25b - Aries

Radius: Rp = √ 1 - 0,9778 · 0.959 = 0,142888RJ · 100 = 14,2888% more big than the earth radius. Compared to academic google results and NASA files, the radius is 1,19RJ and the mass is 0.567MJ.

Creation of linear regression with the RStudio program

To finish with this section, we use the RStudio program to be able to generate a regression line. This will provide us with a series of coefficients and data that will delimit the mass of our planet.

First, you had to go to a NASA exoplanet finder, and select a total of 78 of these. Then, converting the file into csv, we upload it to RStudio, and write the following codes.

With them a graph or diagram was obtained, which was not valid, so we opted to use the coefficients provided by the codes. Finally, with them you have to make a calculation of logarithms, which consists of: log (radius) = coefficient log (mass). If we substitute, it would be this: log (1148) = (-0,7436) log (x), what would it give 7,67295·10^-5, the mass of my exoplanet.
