| dc.description | We report the results of our observations of the nebular complex MH9/10/11, associated with the ULX HoIX X-1, with scanning Fabry-Perot Interferometer. Two regions differing by their kinematics and line ratios may be distinguished, roughly corresponding to the bubble nebula MH9/10 and fainter HII-region MH11. For MH9/10 we find the expansion rate of 20-70km/s that is different for the approaching and receding parts. MH11 is characterised by very low velocity dispersion (less than or about 15km/s) and nearly constant line-of-sight velocities. Properties of MH11 may be explained by photoionization of gas with hydrogen density of about 0.2cm^-3. Luminosity required for that should be of the order of 10^39erg/s. Similar power source is required to explain the expansion rate of MH9/10. Modelling results also indicate that oxygen abundance in MH11 is about solar. | |
