Astrochemical modeling is needed for understanding the formation and evolution of interstellar molecules, and for extracting physical information from spectroscopic observation of molecular lines. The modeling usually involves handling of […]

New Insight Into The Origin Of Water On Earth
Scientists have found the interstellar organic matter could produce an abundant supply of water by heating, suggesting that organic matter could be the source of terrestrial water. There remains a […]
A Twist On The Reaction Of The CN Radical With Methylamine In The Interstellar Medium
Despite the fact that the majority of current models assume that interstellar complex organic molecules (iCOMs) are formed on dust-grain surfaces, there is some evidence that neutral gas-phase reactions play […]
Impact of PAH Photodissociation on the Formation of Small Hydrocarbons in the Orion Bar and the Horsehead PDRs
We study whether polycyclic aromatic hydrocarbons (PAHs) can be a weighty source of small hydrocarbons in photo-dissociation regions (PDRs). We modeled the evolution of 20 specific PAH molecules in terms […]
Graphene Molecules Contributing to the Infrared Bands of Carbon Rich Planetary Nebulae
It is well known since 2010 that fullerene C60 is widespread through the interstellar space. Also, it is well known that graphene is a source material for synthesizing fullerene. Here, […]
Cometary Glycolaldehyde As A Source Of Pre-RNA Molecules
Over 200 molecules have been detected in multiple extraterrestrial environments, including glycolaldehyde (C2(H2O)2, GLA), a two-carbon sugar precursor that has been detected in regions of the interstellar medium. Its recent […]
Dying Stars Breathe Life Into Earth
As dying stars take their final few breaths of life, they gently sprinkle their ashes into the cosmos through the magnificent planetary nebulae. These ashes, spread via stellar winds, are […]
First Detection Of 13CH In The Interstellar Medium
In recent years, a plethora of high spectral resolution observations of sub-mm and FIR transitions of methylidene (CH), have demonstrated this radical to be a valuable proxy for H2, that […]
Constraints Of The Formation And Abundances Of Methyl Carbamate, A Glycine Isomer, In Hot Corinos
Methyl carbamate CH3OC(O)NH2 is an isomer of glycine. Quantum chemical analyses show that methyl carbamate is more stable isomer than glycine. Because of this, there could be a higher chance […]
High-Sensitivity Observations of Molecular Lines with the Arecibo Telescope
We report on one of the highest sensitivity surveys for molecular lines in the frequency range 6.0 to 7.4 GHz conducted to date. The observations were done with the 305m […]
