Exoplanets have been the subject of curiosity and wonder for astronomers and the general public alike since the first discovery of an exoplanet in the 1990s, and their once-elusive characteristics continue to be unveiled with the latest research. Moreover, the advent of more powerful space telescopes such as Kepler, TESS, and Spitzer underscores the integral role of technological breakthroughs in making advancements in exoplanetary science, and as a result, several efforts have been made to inform the design of experiment for future missions. Exocartographer, a Python code written by a group of exoplanet researchers led by Ben Farr (University of Oregon), aims to accomplish this by simulating time-resolved light curve data of an exoplanet and extracting from it the exoplanet’s orbital parameters and an albedo map of its surface. However, this process is still a computational challenge for Exocartographer which must be resolved prior to its use in design experimentation. During this presentation, speaker Emilie Lafleche will detail her summer research with supervisor Nicolas Cowan (McGill University) pertaining to improving the efficiency and function of Exocartographer, and discuss potential groundbreaking implications of mapping exoplanet surfaces with future direct imaging telescopes for the fields of astrobiology, planetary science, and engineering.
