Is N44C a fossil X-ray ionized nebula?
Description
Observations of the H II region N44C in the Large Magellanic Cloud show that the stellar temperature is far too low to account for the high excitation of the nebula. In particular the strong nebular He II 4686-A recombination radiation cannot be attributed for ionization by the stellar ultraviolet flux. Here we propose an alternative interpretation in terms of a (fossil) X-ray photo-ionized nebula resembling the recently discovered He III region around the luminous X-ray binary LMC X-1. (author)
