Sulfur chemistry (DMS, DMDS, H2S) is a promising biosignature class for sub-Neptunes with hycean (ocean-rich) interiors, but abiotic sulfur chemistry pathways via organosulfur compound formation and photochemistry are still poorly constrained

vf_c08b5770c820d45fSulfur biosignature optimization for hycean sub-Neptunes conflicts with current non-detection of DMS on K2-18b (a candidate hycean world), suggesting either hycean pathways are not favorable or DMS detection is too challenging
