Abstract
We preset spectral line observations using MERLIN interferometer towards the massive star forming region IRAS 05137+3919. The Multi Element Radio Linked Interferometer Network (MERLIN) is an array of radio telescopes spread across Great Britain. The array has seven radio telescopes and is run by Jodrell Bank Observatory, the University of Manchester. MERLIN was used to observe the OH maser 1665 MHz line. MERLIN, with a 217 km diameter, gives a high angular resolution of 0.2 arcsecond at this 1665 MHz correspond to the 18-cm wavelength. The maser emission was detected and 13 OH maser spots at 1665-MHz line were drawn. There is one left hand circular polarization (LHC) and 12 right hand circular polarization (RHC) spots. We present the parameters of the OH maser components, namely the velocities, peak intensities and positions for each spot. We show the spatial distribution of the OH maser spots and show the distribution of their velocities of the left and right hand circular polarization components. It has been shown that the detected OH masers trace the central material of this star forming region close to the protostellar source.
