“Determining Distances to RR Lyrae Stars via Photometric Analysis”
For our research project we utilized the Las Cumbres Observatory (a robotic network of telescopes) to capture images of three RR Lyrae stars over a period of two weeks. We obtained the stars' respective apparent magnitudes in four different light filters via photometric analysis. The absolute magnitudes of the RR Lyrae stars were then determined via the period-luminosity relationship. Distances were finally determined by comparison of the absolute magnitude against the apparent magnitude for each star. We will present our photometrically determined distances and compare them to parallax distances from the Gaia Mission.
This research was done as part of the Our Solar Siblings project. Developed by Dr. Michael Fitzgerald (Edith Cowan University), the mission of Our Solar Siblings includes support for a broad range of students interested in participating in astronomy research. Our particular project was designed to take students with no astronomy background and guide them from the research concept through submission to a peer-review journal in 14 weeks.
