Determining The Rotational And Orbital Velocities Of Objects In The Solar System, Mark Jones
Determining The Rotational And Orbital Velocities Of Objects In The Solar System, Mark Jones
Undergraduate Honors Theses
Astronomers have been observing the night sky for many centuries to establish a better understanding for our universe and solar system. As part of their observations, astronomers characterize celestial bodies by fundamental properties such as mass, motion, and composition in order to provide further insight about the objects in question. As technology and science have evolved, the methods for measuring these properties have become more precise and accurate. One such methodology is known as spectroscopy, and it is a significant tool for observational astronomy. In this paper, we shall describe how we used astronomical spectroscopy to determine orbital and rotational …
Flickering Analysis Of Ch Cygni Using Kepler Data, Thomas Holden Dingus
Flickering Analysis Of Ch Cygni Using Kepler Data, Thomas Holden Dingus
Undergraduate Honors Theses
Utilizing data from the Kepler Mission, we analyze a flickering phenomenon in the symbiotic variable star CH Cygni. We perform a spline interpolation of an averaged lightcurve and subtract the spline to acquire residual data. This allows us to analyze the deviations that are not caused by the Red Giant’s semi-regular periodic variations. We then histogram the residuals and perform moment calculations for variance, skewness, and kurtosis for the purpose of determining the nature of the flickering. Our analysis has shown that we see a much smaller scale flickering than observed in the previous literature. Our flickering scale is on …
