Transient Sulfate Aerosols as a Signature of Exoplanet Volcanism

Krissansen-Totton, Joshua; Sholes, Steven; Misra, Amit +1 more

Geological activity is thought to be important for the origin of life and for maintaining planetary habitability. We show that transient sulfate aerosols could be a signature of exoplanet volcanism, and therefore a geologically active world. A detection of transient aerosols, if linked to volcanism, could thus aid in habitability evaluations of th…
