Professional Interests

Dr. Pagnotta is interested in a wide variety of stellar explosions, specifically those that occur on and in white dwarfs, the leftover cores of stars like our Sun, everything from classical novae to Type Ia supernovae. She uses a variety of observational tools to conduct her research across the entire electromagnetic spectrum, from the latest space X-ray telescopes to archival glass plates taken more than a century ago. Dr. Pagnotta is currently working on a survey program to determine how novae behave after their eruptions, and continues to remain interested in solving the Type Ia supernova progenitor problem.
