Detecting Extrasolar Planets With Photometry Using AstroImageJ

Abstract

This study aims to investigate the presence of exosolar planets by utilizing multi-aperture photometry to detect subtle changes in star brightness. This method to detect exosolar planets is currently one of the most successful ways to do this. Existing methods of exoplanet detection, such as radial velocity and direct imaging, have some limitations that the transit method we will be using can address. Direct imaging methods do not work well for planets close to their stars, and radial velocity methods do not allow for a determination of the planetary radius. In our research, we will use AstroImageJ to perform photometry on star systems, monitoring their light curves for periodic dimming indicating an orbiting planet. Our findings will suggest whether or not we can successfully perform photometry with the system we will be using.
