DEFPOS H${\alpha}$ Observations of W80 Complex
Abstract
We present H emission line measurements of the W80 nebular complex. A total of 26 regions have been observed inside the nebula with the Dual Etalon Fabry-Perot Optical Spectrometer (DEFPOS) system at the f/48 Coude focus of 150 cm RTT150 telescope located at TUBITAK National Observatory (TUG) in Antalya/Turkey. The intensities, the local standard of rest (LSR) velocities (), heliocentric radial velocities () and the linewidths at Full Width at Half Maximum (FWHM) of the H emission lines have been determined from these observations. They lie in the range of 259 to 1159 Rayleigh {1R = 10 photons cm sr s = 2.4110 erg cm sr s at H.} (R), 4 to 12 km s and 44 to 55 km s, respectively. The radial velocity measurements show that there are several maxima and minima inside the W80. The new results confirm the literature that complex seems to be rather a uniform in radial velocity and no seen turbulent motion inside the complex. The average value of the calculated the Emission Measure (EM) for the regions is 3.1 pc cm.
