Period Study by the Transit Method with Ground-Based Observations

TL;DR

This study analyzed 19 exoplanets using ground-based transit observations, deriving their orbital parameters and confirming their periods align with existing data, while also providing new measurements of transit times and depths.

Contribution

It presents a comprehensive ground-based observational analysis of multiple exoplanets, including orbital parameters and host star characterization, using data reduction and online software tools.

Findings

Orbital periods match existing catalogs

Transit times and depths were measured

Host stars plotted on H-R diagram

Abstract

In this study, 19 exoplanets were studied. Their photometric observations were obtained from the ETD. After performing the data reduction steps, its parameters were obtained through Exofast online software. Then calculated orbital parameters of planets and as a result, the periods of all the planets in this study match comparable with the Extrasolar Planets Encyclopedia. Also, we present Tc and Tdepth obtained from the observations. The location of the host stars in this study was also plotted in the H-R diagram.
