The Efficiency of Stellar Reionization: Effects of Rotation, Metallicity, and Initial Mass Function

Michael W. Topping, J. Michael Shull

We compute the production rate of photons in the ionizing Lyman continua (LyC) of H I (lambda < 912 A), He I (lambda < 504 A), and He II (lambda < 228 A) using recent stellar evolu…
