Dr. Durrell studies open and globular star clusters in our Milky Way Galaxy. By measuring the brightnesses and colors of these stars, astronomers can determine the age and chemical content of these stars, and gain clues as to how our Galaxy was formed. On the left is an image of the globular cluster NGC 6093.
Dr. Feldmeier studies stars that vary in brightness. By studying which stars vary and which stay constant in brightness, astronomers can learn about the interiors of stars and search for extra-solar planets. On the left is a light curve of the RR Lyrae variable star CL Boo.
