Material Properties of Super-Earths and mini-Neptunes

The most common planets in the galaxy are now known to be low-mass exoplanets that either are rocky, known as super-Earths or may have an incipient envelope, the so-called mini-Neptunes. As the data grows for measured masses and radius for these planets the types of questions that we aim to answer have moved from discovery to characterization. I will talk about synergies between the study of material properties in the PT regime of these planets and the inferences we are able to make now in terms of composition and structure.
