Histogram of the core ice mass fractions of the 2222 synthetic planets in the TRAPPIST-1 region (M > 0.1 M⊕, a < 0.1 au). The shown population of synthetic planets is calculated around a 0.1 M⊙ star with 50embryos (NGM10). Most planets are purely rocky, but 314 (14%) show ice fractions larger than 0.1.
