TL;DR
This study investigates the chemical pathways for interstellar adenine formation, highlighting the most dominant precursors and providing spectral data to aid future observational detection in space.
Contribution
It introduces new formation pathways for adenine in interstellar medium and assesses their significance using a comprehensive chemical model.
Findings
The new pathways significantly contribute to adenine formation.
Two precursors, C3NH and HNCNH, are key targets for observations.
Spectral data for adenine and precursors are provided.
Abstract
It is long debated if pre-biotic molecules are indeed present in the interstellar medium. Despite substantial works pointing to their existence, pre-biotic molecules are yet to be discovered with a complete confidence. In this paper, our main aim is to study the chemical evolution of interstellar adenine under various circumstances. We prepare a large gas-grain chemical network by considering various pathways for the formation of adenine. Majumdar et al. (2012) proposed that in the absence of adenine detection, one could try to trace two precursors of adenine, namely, HCCN and NH_2CN. Recently Merz et al. (2014), proposed another route for the formation of adenine in interstellar condition. They proposed two more precursor molecules. But it was not verified by any accurate gas-grain chemical model. Neither was it known if the production rate would be high or low. Our paper fills this…
