Students at YSPA work in teams of four on an astrophysical research project that requires them to get data using telescopes at the Leitner Observatory (LFOP), such as our 0.4-meter Ritchey-Chretien Telescope shown here to the right with YSPA students, as well as from remote observatories in New Mexico, California, Chile, and Australia. Once students have sufficient data, they use the python programing language and scientific python libraries to make a model that best fits and explains their data.
The specific research project at YSPA changes from year to year, but the project always involves generating a scientific model for a phenomenon based on data collected by the students themselves using LFOP and other remote telescopes.
In 2023, all students will work on modeling the photometric light curves and spectra of extra-galactic supernovae. These are massive stars that have exploded with tremendous luminosity in distant galaxies, and by studying how these exploding stars fade with time, we can learn a lot about the physics of stellar core collapse, and we can potentially learn about the stellar populations of distant galaxies. In some cases, we are even able to independently measure the distance to a galaxy and determine the expansion rate of the Universe!
In addition to the main research project of studying extra-galactic supernovae, students will complete several smaller projects using their own data, such as estimating the star-formation rate of spiral galaxies through H-alpha imaging, measuring the cosmic-ray radiation level in the Earth’s stratosphere (using a helium balloon), measuring the age and distance to a galactic star cluster, and measuring the rotation of the Milky Way Galaxy using a radio telescope.
At the end of the program, each research team writes a report on their project in the form of a scientific paper, and they present their results at a mini-conference where they get feedback from the Yale Astronomy faculty and other students.
After YSPA, some students may want to continue to work on their research project and expand it for a science fair or talent search program, or as a senior capstone project at their high school. Some projects may turn into published papers in referenced science journals.
