The distinctive colour is due to the spectral line emission when an ionised electron recombines with a proton to form neutral hydrogen. The two spectra below are both of the Eta Carinae H II region. WebThe integral field unit (IFU) spectroscopic view of extended ionized nebulae, such as planetary nebulae (PNe), H II regions, and galaxies, has changed the approach of studying these objects, providing a simultaneous characterization in both spatial directions. However, the spatial spaxel-by-spaxel analysis of such nebulae through IFUs is not directly … highdateとは
