Exploring the Enceladus molecular environment with the LMT

Enceladus is one of the most promising ``ocean world" of the Solar System for detecting molecular precursors to life, as it ejects into space a large quantity of material from a series of geysers. This material is thought to arise from an underground ocean. We present a spectroscopic monitoring program in the millimeter regime that will make use of the SEQUOIA spectrometer attached to the single-dish 50 m Large Millimeter Telescope. We expect to detect many molecular species (e.g., HCN, H_2CO, NH_2CHO, CH_3OH, and CO) in the Enceladus' torus and, through recurrent observations, explore their time variability.
