Evidence date ·What LHS 3844 b’s heat can tell us about its rocky surface
PreprintJWST’s infrared measurements favor models of a dark, low-silica surface on LHS 3844 b. They cannot yet distinguish an old weathered surface from a fresh slab.

Evidence date ·Searching Kepler for a planet’s single crossing leaves an orbital puzzle
PreprintAn ensemble reads stellar brightness and spacecraft diagnostics to flag single transits. Tests assess recovery; KOI 1271.02 still needs more observations.

Evidence date ·Measuring TRAPPIST-1’s extra infrared light could help preserve Webb’s planet observations
PreprintFour TRAPPIST-1 flares show how up to 80% of their interference could be removed from Webb data, and why that does not establish a planet’s atmosphere.
