Another productive summer of undergraduate research!
Vedant Chandra (advisors: graduate student Hsiang-Chih Hwang, Prof. Zakamska) applied machine-learning techniques to the analysis of spectra of white dwarfs — compact remnants of stars like the Sun. The spectral features he can extract from the white dwarf spectra can give precise measurements of white dwarf temperature, surface gravity and mass. Vedant has two papers in preparation based on his summer 2019 research internship.
Evan Petrosky (advisors: graduate student Hsiang-Chih Hwang, Prof. Zakamska) analyzed 200,000 variable objects in the Wide-field Infrared Survey Explorer (WISE) data archive, learned to identify periodic variables, to measure their periods and to analyze their lightcurves. Evan is preparing a paper based on his summer 2019 research internship.
Shuchen Zhang (advisors: graduate student Hsiang-Chih Hwang, Prof. Zakamska) explored the emerging archive of the NASA Transiting Exoplanet Survey Satellite (TESS), learned to visualize variability data, to classify different kinds of stellar variability and to understand their physical nature.
Katherine Xiang (advisor: Dr. David Nataf) continued her project started during the summer 2018 research internship and is wrapping up her paper on buckling galactic bars in simulations and in observations.
