The Night of Several Transits: Probing Stellar Behavior and Planetary Diversity in K2-384 — This DDT project targets the active M dwarf K2-384, which hosts five transiting planets. During July 10-11, 2025, three planets will transit sequentially within 13 hours, allowing JWST/NIRSpec-PRISM spectroscopy to isolate stellar contamination and model stellar heterogeneity. The data will constrain K2-384f’s atmospheric composition and support development of new retrieval models, improving JWST strategies for studying planets around active M dwarfs.
