A spectral survey of CH3CCH in the Hot Molecular Core G331.512-0.103
Julia C. Santos, Leonardo Bronfman, Edgar Mendoza +4
A spectral survey of methyl acetylene (CH3CCH) was conducted toward the hot molecular core/outflow G331.512-0.103. Our APEX observations allowed the detection of 41 uncontaminated…
HCN/HNC chemistry in shocks: a study of L1157-B1 with ASAI
B. Lefloch, G. Busquet, S. Viti +9
HCN and its isomer HNC play an important role in molecular cloud chemistry and the formation of more complex molecules. We investigate here the impact of protostellar shocks on the…
Isocyanic acid (HNCO) in the Hot Molecular Core G331.512-0.103: Observations and Chemical Modelling
Carla M. Canelo, Leonardo Bronfman, Edgar Mendoza +5
Isocyanic acid (HNCO) is a simple molecule with a potential to form prebiotic and complex organic species. Using a spectral survey collected with the Atacama Pathfinder EXperiment…
The distribution of open clusters in the Galaxy
H. Monteiro, D. A. Barros, W. S. Dias +1
In this work we explore the new catalog of galactic open clusters that became available recently, containing 1750 clusters that have been re-analysed using the Gaia DR2 catalog to…
Elemental abundances in the center of the Galactic Nuclear Disc
V. V. Kovtyukh, S. M. Andrievsky, R. P. Martin +5
We have made the first attempt to derive the chemical properties of the Galactic disc at its very central part using high-resolution infrared spectroscopic observations of four cla…
Cyanoacetylene in the outflow/hot molecular core G331.512-0.103
N. U. Duronea, L. Bronfman, E. Mendoza +10
Using APEX-1 and APEX-2 observations, we have detected and studied the rotational lines of the HCN molecule (cyanoacetylene) in the powerful outflow/hot molecular core G331.512…
