چکیده
The studies of the complex molecular emission lines in millimeter and submillimeter wavelengths towards hot cores demonstrate valuable details about chemical complexity interstellar medium (ISM). We presented first detection rotational organic molecule methyl formate (CH$_{3}$OCHO) core region IRAS 18566+0408 using high-resolution Atacama Large Millimeter/Submillimeter Array (ALMA) band 3 observation. estimated column density CH$_{3}$OCHO diagram analysis was (4.1$\pm$0.1)$\times$10$^{15}$ cm$^{-2}$ with temperature 102.8$\pm$1.2 K. fractional abundance relative to hydrogen (H$_{2}$) 3.90$\times$10$^{-9}$. noted that is fairly consistent simulation value predicted by three-phase warm-up model from Garrod (2013). also discussed possible formation mechanism cores.

Formation of methyl formate and other organic species in the warm-up phase of hot molecular cores
Context. xxx Aims. The production of saturated organic molecules in hot cores and corinos is not well understood. The standard approach is to assume that, as temperatures heat up during star formation, methanol and other species evaporate from grain surfaces and undergo a warm gas-phase chemistry at 100 K or greater to produce species such as methyl formate, dimethyl ether, and others. But a se...
متن کاملDetection of vibrationally excited methyl formate in W51 e2
Context. Hot cores in molecular clouds, such as Orion KL, Sgr B2, W51 e1/e2, are characterized by the presence of molecules at temperature high enough to significantly populate their low-frequency vibrationally excited states. For complex organic molecules, characterized by a dense spectrum both in the ground state and in the excited states, such as methyl formate, ethyl cyanide or dimethyl eth...
متن کاملThe Evolution of the First Core in Rotating Molecular Core
The standard star formation scenario is based on spherically symmetric radiative hydrodynamics calculations. In this paper, we focus on the evolution of the rotating non-spherical cloud through the first core and second collapse phases 10 < ρ < 10 3 g cm using axisymmetric numerical calculations. The rotating first core evolves under the influence of mass and angular momentum accretion from the...

within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
Detection and Molecular Characterization of Avian Metapneumovirus in Iran: The First Report
Avian pneumovirus (APV) causes turkey rhinotracheitis (TRT) and swollen head syndrome (SHS) of chickens, which is usually accompanied by secondary bacterial infections that increase mortality. In Iran, some serological studies indicated that APV infection is endemic in commercial poultry industry. In this study we diagnosed APV genome molecularly in suspected broiler flock (4 weeks) in Iran and...
