A New Warm Molecular Clump toward the Star Forming Region G34.26+0.15. (2000). Revista Mexicana De Astronomía Y Astrofísica, 36(1), 161-169. https://astronomia.unam.mx/journals/rmxaa/article/view/2000rmxaa..36..161g

Abstract

In this work we reanalyze VLA ammonia (2,2) and (3,3) observations toward the massive star forming region G34.26+0.15. We find one new ammonia clump with (2,2) and (3,3) emission toward the northwest in addition to the main molecular structure previously reported. The new clump is associated with water maser spots and we estimate for it a rotational temperature of ~ 54 ± 12 K, a diameter of 0.15 pc (assuming a distance of 3.8 kpc) and a molecular mass of ~ 10 Msolar (assuming an [H2/NH3] ratio of 107). These results suggest that the clump could have an embedded star and that in addition to the massive stars that excite the H II regions previously reported, there may be other young stars of lower mass in the region.
