羟胺(NH2OH)的选择性天文源搜索

A Search for Hydroxylamine (NH2OH) toward Select Astronomical Sources

Robin L. Pulliam, Brett A. McGuire, Anthony J. Remijan

摘要:

本文报道了利用位于基特峰的NRAO 12 m望远镜对IRC+10216、Orion KL、Orion S、Sgr B2(N)、Sgr B2(OH)、W3IRS5和W51M的14次羟胺(NH_2OH)转动跃迁的观测结果。尽管最近的模型表明存在高丰度的NH2 OH,但这些观察结果导致未检测到。计算出的上限比模型预测的要低六个数量级。可能的解释低于预期的丰度进行了探讨。

英文摘要:

Observations of 14 rotational transitions of hydroxylamine (NH2OH) using the NRAO 12 m Telescope on Kitt Peak are reported towards IRC+10216, Orion KL, Orion S, Sgr B2(N), Sgr B2(OH), W3IRS5, and W51M. Although recent models suggest the presence of NH2OH in high abundance, these observations resulted in non-detection. Upper limits are calculated to be as much as six orders of magnitude lower than predicted by models. Possible explanations for the lower than expected abundance are explored.
