At best, we typically only know the mass and radius of exoplanets. But really, when we find rocky planets we'd like to know whether their interiors are similar or dissimilar to that of the Earth. Conventionally, this is impossible, as there are simply too many possible models and just two measured quantities. In a new research paper from our group, the Cool Worlds Lab here at Columbia University, we think we've helped crack at least part of the problem. Our new model, called HARDCORE, is explained in this video by the lead author and rising senior undergraduate at Columbia, Gabrielle Suissa - enjoy!
