Abstract | dc.description.abstract | Investigating the physical and chemical structures of massive star-forming regions is critical for understanding the formation and
the early evolution of massive stars. We performed a detailed line survey toward six dense cores named as MM1, MM4, MM6,
MM7, MM8, and MM11 in G9.62+0.19 star-forming region resolved in ALMA band 3 observations. Toward these cores, about
172 transitions have been identified and attributed to 16 species including organic Oxygen-, Nitrogen-, Sulfur-bearing molecules
and their isotopologues. Four dense cores MM7, MM8, MM4, and MM11 are line rich sources. Modeling of these spectral lines
reveals the rotational temperature in a range of 72−115 K, 100−163 K, 102−204 K, and 84−123 K for the MM7, MM8, MM4,
and MM11, respectively. The molecular column densities are 1.6 × 1015 − 9.2 × 1017 cm−2
toward the four cores. The cores
MM8 and MM4 show chemical difference between Oxygen- and Nitrogen-bearing species, i.e., MM4 is rich in oxygen-bearing
molecules while nitrogen-bearing molecules especially vibrationally excited HC3N lines are mainly observed in MM8. The
distinct initial temperature at accretion phase may lead to this N/O differentiation. Through analyzing column densities and
spatial distributions of O-bearing Complex Organic Molecules (COMs), we found that C2H5OH and CH3OCH3 might have
a common precursor, CH3OH. CH3OCHO and CH3OCH3 are likely chemically linked. In addition, the observed variation in
HC3N and HC5N emission may indicate that their different formation mechanism at hot and cold regions. | es_ES |
