b'2018-2019 YEAR BOOK9This artists rendition shows a very hot gas exoplanet with more carbon than oxygen (orange sphere), the first carbon-rich planet discovered. Dubbed WASP-12b, it was found by NASAs Spitzer Telescope some 1,200 light years away in the Auriga constellation. Sally June Tracy and Peter Driscoll are studying the interiors of carbon-rich super-Earths to understand the structure and evolution of these objects. Image courtesy NASA/JPL-Caltech/R. Hurt (SSC)Probing ExoplanetsCarnegie researchers continued to do forefront work in the study of exoplanets, conducting lab-based, high-pressure and high-temperature experiments that will provide insights into the structure and evolution of these far-off worlds. Working with colleagues at Princeton University and Lawrence Livermore National Laboratory, Geophysical Laboratory staff scientist Sally June Tracy and Terrestrial Magnetisms Peter Driscoll used a laser-driven process to mimic the conditions inside the planetary mantles of carbon-rich super-Earths. Their study of the structure of silicon carbide under these extreme conditions provides new data that will be used to develop more accurate models of these exoplanetary interiors.'
