| الوصف: | We present high angular resolution ( ∼ 1 ′ ′ ) multi-tracer spectral line observations toward the hot core associated with G34.26+0.15 between 87–109 GHz. We have mapped emission from (i) complex nitrogen- and oxygen-rich molecules like CH3OH, HC3N, CH3CH2CN, NH2CHO, CH3OCH3, HCOOCH3; (ii) sulfurbearing molecules like OCS, SO and SO2; and (iii) the recombination line H53β. The high angular resolution enables us to directly probe the hot molecular core associated with G34.26+0.15 at spatial scales of 0.018 pc. At this resolution we find no evidence for the hot core being internally heated. The continuum peak detected at λ = 2.8 mm is consistent with the free-free emission from component C of the ultracompact H ii region. Velocity structure and morphology outlined by the different tracers suggest that the hot core is primarily energized by component C. Emission from the N- and O-bearing molecules peak at different positions within the innermost regions of the core; none are coincident with the continuum peak. Lack of high resolution complementary datasets makes |
