Radius Study of Ten Transiting Hot Jupiter Exoplanets with Ground-Based Observations

TL;DR

This study analyzes 14 light curves of 10 hot Jupiter exoplanets using ground-based observations and compares the derived radii with NASA data, demonstrating the effectiveness of small telescopes in exoplanet characterization.

Contribution

It presents a method for analyzing hot Jupiter transits with small telescopes and validates the results against established NASA data.

Findings

Good agreement between EXOFAST and NASA radius values.

Small telescopes can produce significant exoplanet data with proper skills.

Ground-based observations are viable for exoplanet radius measurements.

Abstract

In this research, 14 light curves of 10 hot Jupiter exoplanets available on Exoplanet Transit Database (ETD) were analyzed. We extracted the transit parameters using EXOFAST software. Finally, we compared the planet's radius parameter calculated by the EXOFAST with the value at the NASA Exoplanet Archive (NEA) using the confidence interval method. According to the results obtained from this comparison, there is an acceptable match for the planet's radius with NEA values. Also, based on the average value of 350 mm optics in this study, it shows that the results obtained using small telescopes can be very significant if there is appropriate observational skill to study more discovered planets.
