Scientific paper

AFGL 2591 is a prototypical, deeply embedded high-mass protostar, but is crucially and unusually for high-mass YSOs isolated from the irradiation of associated protostars. We have observed and modeled line emissions of X-ray sensitive molecules. The observed abundance of these molecules can only be interpreted by strong X-ray emission of the central object. Our models indicate that the X-ray emission must be at a level that is observable in a 30 ks observation. A non-detection would be a strong disagreement. A detection would be the first X-ray emission inferred by indirect means and a crucial test of the chemical modeling of the impact of high-energy radiation on the environment of young stars.
