Exoplanets smaller than Neptune are common around red dwarf (M-dwarf) stars, and many of those that transit their host stars constitute the bulk of known temperate worlds ideal for atmospheric characterization. However, whether the small exoplanets surrounding red dwarfs are potentially habitable remains unclear, partly due to our lack of understanding of their composition. In new research, University of Chicago’s Dr. Rafael Luque and Dr. Enric...
