TULIPS helps visualize the physics of how stars evolve over time in an intuitive manner. Instead of complex diagrams, stars are represented as circles that change in size and color over time. I have been developing TULIPS since 2018 and plan to publish it as open-source and free software in the first half of 2021.
With the Outreach award of the Royal Holland Society of Sciences and Humanities, I am planning to further develop TULIPS and to make tutorials and videos of TULIPS available. Stay tuned!
For more information, have a look at a one-hour presentation I gave about TULIPS at a lunch seminar of the Anton Pannekoek Institute, University of Amsterdam:
