Remote Observing and Spectroscopy!

During our Foundations of Science class in March 2015, we were able to use our Brackett Observatory at Pomona College in the afternoon class time to gather some amazing stellar spectra! ┬áThese spectra were taken using an Alpy stellar spectrograph, with help from Pomona’s Franklin Marsh (’17). The data will be analyzed by the class to study stars that could be hosting planetary systems. We will look at the absorption lines in the spectra to determine the “habitability” of a potential solar system around the star. Within the spectra are some from Jupiter and the Moon, and we will also look at those spectra to see if we can detect the presence of the atmosphere of Jupiter and to analyze a solar spectrum.
