THE INTERACTION OF RECENTLY DISCOVERED HOT STARS WITH GALACTIC CENTRE THERMAL RADIO EMISSION FILAMENTS

our kao observations of the galactic center arched filaments show that the fir excitation is consistent with ionization by stars, as opposed to more exotic phenomena such as magnetohydrodynamic induced ionizations. our subsequent groundbased observations have revealed a tight cluster of probable wn89 stars located near the e1 filament. based on our hii region models, an excitation gradient in the fir lines will be evident if the cluster is responsible for the ionization of the e1 filament. we propose observations of siii (33 microns), siii (35 microns), oiii (52 and 88 microns), niii (57 microns), oi (63 microns), nii (122 microns), cii (158 microns) and the 40196 micron continuum at 3 positions at varying distances from the g0.12+0.02 cluster to test whether this cluster photoionizes the arched filaments and the relationship between the cluster and an adjacent molecular cloud. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
