Abstract

The exoplanet HAT-P-12b was observed at the Sierra Remote Observatories by a 0.7 meters diameter reflective robotic telescope CDK700 with the CCD photometric technique. This research using 317 images of the HAT-P-12b on April 14, 2017. They were analyzed the photometric photometry and calculated the physical properties by the AstroImageJ program. The results show that the radius of the exoplanet HAT-P-12b is 0.951 RJ, orbital period P about 3.2105 days. The center of page traverse Tc is 2457857.166110000 (BJD) and the total time of traverse T is 0.093519 days. The Star and Exoplanet View program was created the HAT-P-12b model that the decreasing brightness with 1.94864 percent the average distance between the exoplanet HAT-P-12b and the center is 0.0388 AU.

Summary

Introduction

Planet that is outside the solar system (Extrasolar-planet) or shortly known as exoplanets (Exoplanet) was discovered in 1995 by two scientists, Meyer and Queloz. The 51Peg b is a planet with a mass is 0.7 Jupiter-mass It has a short orbit about 4 days and an average distance is 0.05 AU from its mother star. The objectives of the study about the exoplanet are explored the planets outside the solar system or orbit planets around other stars and compare the characteristics of the exoplanets and in our solar system. The most important goal of the exploration is the opportunity to discover Earthlike planets that both of size and distance from the main sequence stars of the same spectrum as the Sun. The simple observation of the exoplanet is the light curve analysis. The AstroImageJ can automatically adjust the model to match the data point and report its physical properties
