Detecting Exosolar Planets Using Photometry with AstroImageJ
Tuesday April 22, 2025 2:00pm - 3:30pm CDT
Davies Center: Ojibwe Ballroom (330)
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.

The Effects of Stellar Winds on the Orbits of Planets Around Massive Stars
Tuesday April 22, 2025 2:00pm - 3:30pm CDT
Davies Center: Ojibwe Ballroom (330)
Our project aims to discover the effects that solar winds have on the orbital pathways of planets around massive stars. This will allow us to understand why some planets survive in the habitable zone while others are terminated. With the usage of the computer program MESA, we have been able to closely model the mass loss rates of stars while simultaneously tracking the evolution of test planet orbits. This newly discovered knowledge will allow us to develop a deeper understanding about the life and development of star systems outside our solar system.
