Abstract
We discuss general relativistic effects in the steady state neutrino-driven "wind" that may arise from nascent neutron stars. In particular, we generalize previous analytic estimates of the entropy per baryon S, the mass outflow rate , and the dynamical expansion timescale τdyn. We show that S increases and τdyn decreases with increasing values of the mass-to-radius ratio describing the supernova core. Both of these trends indicate that a more compact core will lead to a higher number of neutrons per seed nucleus. Such an enhancement in the neutron/seed ratio may be required for successful r-process nucleosynthesis in neutrino-heated supernova ejecta.Keywords
