Description
We report here on the discovery of faint extended wings of Hα observed out to an apparent velocity of ∼7600 km s⁻¹ in the Orion Nebula (M42) and in five H II regions in the Large and the Small Magellanic Clouds. We show that these wings are caused by Raman scattering of both the O I and Si II resonance lines and stellar continuum UV photons with H I followed by radiative decay to the H I n = 2 level. The broad wings also seen in Hβ and in Hγ result from Raman scattering of the UV continuum...[Show more]
