Question: What is the smallest possible radius?
SQL: SELECT MIN("radius_r") FROM "prominent_stars_in_pismis_24";

Question: What are all the spectral types for star mismis24-# is 1sw?
SQL: SELECT "spectral_type" FROM "prominent_stars_in_pismis_24" WHERE "star_pismis24_num"='1SW';

Question: If a radius is 10, what  is the lowest possible mass?
SQL: SELECT MIN("mass_m") FROM "prominent_stars_in_pismis_24" WHERE "radius_r"=10;
