Abstract

This abstract is about the techniques of mission learning which was learnt in the
sessions. First, a time array with 2000 points was created, and it represented time in
days by separating x axis into 2000 points. Secondly, an initializing of flux arrays with
ones, thus representing stellar flux without any transit was done. Then, each transit
center was looped through and created a transit mask. Mission learning was for
detecting exoplanets, and training and testing model was required. Transits is a way to
detect exoplanet as the planet passing in front of its star dims the light of the star
slightly. Therefore, by catching the sudden change in light of the planet showed in the
model, it could be used to determine if there was an exoplanet. The data showed by the
graph could convey the light received over a period of time. By measuring the depths,
we could tell informations about the exoplanet.
