Variations in atmospheric elemental nitrogen can considerably affect the abundance of major nitrogen-bearing species such as NH _3 and HCN. Also, due to vertical mixing and photochemistry, their abundance deviates from thermochemical equilibrium. The

We present the first high spectral resolution mid-infrared survey in the Orion BN/KL region, covering 7.2–28.3 μ m. With SOFIA/EXES, we target the enigmatic source Orion IRc2. While this is in the most prolifically studied massive star-forming reg

The atmospheric metallicity greatly influences the composition of exoplanet atmospheres. The effect of metallicity on the thermochemical equilibrium is well studied, though its effect on the disequilibrium abundance is loosely constrained. In this st

The mobility of lighter species on the surface of interstellar dust grains plays a crucial role in forming simple through complex molecules. Carbon monoxide is one of the most abundant molecules, its surface diffusion on the grain surface is essentia

Comets show a general diversity in their parent volatile composition, but in most cases H2O is observed to be the dominant volatile in terms of abundance. This is followed by CO and CO2, and trace amounts of other species such as CH4, CH3OH, O2, and

The First Mid-infrared Detection of HNC in the Interstellar Medium: Probing the Extreme Environment toward the Orion Hot Core. Astrophysical journal, 907(1), p. 51. Institute of Physics Publishing IOP 10.3847/1538-4357/abca36
We present the first mid-infrared (MIR) detections of HNC and H13CN in the interstellar medium, and numerous, resolved HCN rovibrational transitions. Our observations span 12.8 to 22.9 micron towards the hot core Orion IRc2, obtained with the Echelon

Comet 2I/Borisov is the first interstellar comet observed in the solar system, providing a unique opportunity to understand the physical conditions that prevailed in a distant unknown planetary system. Observations of the comet show that the CO/H2O r

The occurrence of Venusian lightning must be preceded by electrification of particles in Venusian clouds and separation of these charged particles to form distinct charged regions. In this work, we estimate the minimum required charge and the dimensi
