Mass-Radius Relationships for Exoplanets Alejandro Lorenzo, Arizona State University credit: Hale Telescope, 2010

Exoplanet - a planet outside of the solar system - they all appear to be unique in their own way - change how we study our own SS - how common are we? - Well, its interesting Credit: GPI What are they? Why study them?

Finding an Exoplanet ★ These are the current most popular planet hunting methods ○Transiting method will yield: orbit parameters, inclination and radius ■if host star is sufficiently bright, it is possible to get atmospheric composition, effective temperature/albedo, inner structure and composition constraints ○Radial velocity method will yield: orbit parameters. minimum planet mass (m*sin(i)) Other methods: Direct imaging (IR), microlensing, Timing(pulsars, variable stars), reflected light

Pencil, paper, simulate ★ There are possibly several thousand more planets than we currently know of ○Planet candidates are pending planets that require follow up observations ★ Once confirmed, the next step is to find out what the planets are made of Otherwise…

Conclusions By reasonably extrapolating equations of state, we have calculated for the compression of materials within a planet using a regime that takes into account dense polymorphs and differentiated layers. We have built a user friendly program in Java to carry these calculations. With this program we may consider many models and put constraints on plausible observations.
