论文摘要
使用30米的IRAM射电望远镜，我们观察到3-4和2 mm波长的几个巨大恒星形成区域。来源中气体的温度是根据Ch $ _ {3} $ CCH的线以及从Effelsberg的100米射电视上观测到的NH $ _3 $分子的过渡。结果，H $^{13} $ CN和Hn $^{13} $ C的$ j = 1-0 $转换的集成强度比与动力学温度之间的相关性。获得的结果允许我们提出强度比H $^{13} $ CN-HN $^{13} $ C的使用，作为星际云的可能温度指标。我们还将动力学温度的估计值与尘埃温度$ t_ {dust} $进行了比较。结果，未发现显着相关性。
With the 30-m IRAM radio telescope, we observed several massive star forming regions at wavelengths of 3-4 and 2 mm. The temperature of the gas in the sources was estimated from the lines of CH$_{3}$CCH and from the transitions of the NH$_3$ molecule obtained during observations at the 100-m radio telescope in Effelsberg. As a result, a correlation between the integrated intensity ratios of the $J=1-0$ transitions of H$^{13}$CN and HN$^{13}$C and the kinetic temperature has been obtained. The obtained results allow us to propose the use of the intensity ratio H$^{13}$CN-HN$^{13}$C as a possible temperature indicator of interstellar clouds. We also compared the obtained estimates of the kinetic temperature with the dust temperature $T_{dust}$. As a result, no significant correlation was found.
