Software Development within STScI’s TIKE Server to Increase Accessibility of TESS Exoplanet Transit Data to Introductory Astronomy Students

A sorely underutilized tool in teaching astronomy concepts to new students of astronomy are exoplanet transits. They have the potential to be easy to understand, while demonstrating the concepts of light curves, creating time-series data from a single pixel, how Kepler’s laws can be practically used, and generally how astronomers are able to imply a ...
