    "abstract": "We use chiral perturbation theory to compute the effective nucleon propagator\nin an expansion about low density in the chiral limit. We neglect four-nucleon\ninteractions and focus on pion exchange. Evaluating the nucleon self-energy on\nits mass shell to leading order, we show that the effective nucleon mass\nincreases by a small amount. We discuss the relevance of our results to the\nstructure of compact stars.",
