چکیده

In the interstellar medium, amide-type molecules play an important role in formation of prebiotic hot molecular cores or high-mass star-formation regions. The complex amide-related molecule cyanamide (NH $$_{2}$$ CN) is known as one rare which has a major urea CONH ). this paper, we presented detection rotational emission lines towards core G10.47 $$+$$ 0.03 between frequency range 158.49–160.11 GHz using Atacama Large Millimeter/Submillimeter Array (ALMA) interferometric radio telescope. estimated column density NH CN diagram model was $$N(\mathrm{NH}_{2}\mathrm{CN}) = (6.60\pm 0.1)\times 10^{15}$$ cm $$^{-2}$$ with temperature ( $$T_\mathrm{rot}) 201.2\pm 3.3$$ K. fractional abundance respect to H $$f(\mathrm{NH}_{2}\mathrm{CN}) 5.076\times 10^{-8}$$ . Additionally, CN/NH CHO ratio 0.170, nearly similar IRAS 16293–2422 B and Sgr B2 (M). We found that observed 0.03, fairly agrees theoretical value predicted by Garrod (2013). also discussed possible destruction pathways CN.

Detection of Interstellar Acetone toward the Orion-kl Hot Core

We present the first detection of interstellar acetone [(CH3)2CO] toward the high mass star forming region Orion-KL and the first detection of vibrationally excited (CH3)2CO in the ISM. Using the BIMA Array, 28 emission features that can be assigned to 54 acetone transitions were detected. Furthermore, 37 of these transitions have not been previously observed in the ISM. The observations also s...

CHANDRA DETECTION OF Fe XVII IN ABSORPTION: IRON ABUNDANCE IN THE HOT GASEOUS INTERSTELLAR MEDIUM

The iron depletion level and the gas-phase iron abundance in the hot (∼ 106 K) interstellar medium (ISM) are critical to our understanding of its energy balance as well as the thermal sputtering, cooling, and heating processes of dust grains. Here we report on the first detection of the Fe XVII absorption line at 15.02 Å from the hot ISM in the spectrum of the low mass X-ray binary 4U 1820–303 ...

Towards a Molecular Understanding of the Fanconi Anemia Core Complex

Fanconi Anemia (FA) is a genetic disorder characterized by the inability of patient cells to repair DNA damage caused by interstrand crosslinking agents. There are currently 14 verified FA genes, where mutation of any single gene prevents repair of DNA interstrand crosslinks (ICLs). The accumulation of ICL damage results in genome instability and patients having a high predisposition to cancers...

Detection of 6.7 GHz methanol absorption towards hot corinos

Context. Methanol masers at 6.7 GHz have been found exclusively towards high-mass star forming regions. Recently, some Class 0 protostars have been found to display conditions similar to what are found in hot cores that are associated with massive star formation. These hot corino sources have densities, gas temperatures, and methanol abundances that are adequate for exciting strong 6.7 GHz mase...
