Tools

This page collects together various web-based tools that I've created to support my research and teaching efforts.

Stellar Structure & Evolution

• OC-Web, a collection of web-based interfaces to the codes accompanying the textbook An Introduction to Modern Stellar Astrophysics (Ostlie & Carroll).
• EZ-Web, an on-line stellar evolution code based on Bill Paxton's Evolve ZAMS (EZ) code. I make extensive use of EZ-Web in teaching stellar interiors.
• Poly-Web, an on-line code for calculating polytropes — simplified stellar models that obey a polytropic equation of state.

Time

• An ephemeris tool for predicting the times of periodic phenomena in various stars I'm interested in (MiMeS version here)
• A geochron I created, showing the regions of the Earth's surface in daylight and in shadow.
