Model for Nitric oxide and its dayglow emission in the Martian upper atmosphere using NGIMS/MAVEN measured neutral and ion densities
Susarla Raghuram, Anil Bhardwaj, Maneesha Dharwan
A comprehensive study of Nitric oxide (NO) chemistry in the Martian upper atmosphere is restricted due to the lack of requisite measurements. NO is an abundant form of odd nitrogen…
The similarity of the interstellar comet 2I/Borisov to solar system comets from high resolution optical spectroscopy
C. Opitom, E. Jehin, D. Hutsemékers +11
2I/Borisov - hereafter 2I - is the first visibly active interstellar comet observed in the solar system, allowing us for the first time to sample the composition of a building bloc…
Forbidden atomic oxygen emissions in the Martian dayside upper atmosphere
Susarla Raghuram, Sonal Kumar Jain, Anil Bhardwaj
Recently, Nadir and Occultation for Mars Discovery (NOMAD) ultraviolet and visible spectrometer instrument on board the European Space Agency's ExoMars Trace Gas Orbiter (TGO) simu…
A physico-chemical model to study the ion densitydistribution in the inner coma of comet C/2016 R2(Pan-STARRS)
Susarla Raghuram, Anil Bhardwaj, Damien Hutsemékers +3
The recent observations show that comet C/2016 R2 (Pan-Starrs) has a unique and peculiar composition when compared with several other comets observed at 2.8 au heliocentric distanc…
CO+ first-negative band emission: A tracer for CO in the Martian upper atmosphere
Susarla Raghuram, Anil Bhardwaj
Recently, Imaging Ultraviolet Spectrograph (IUVS) on-board Mars Atmosphere and Volatile EvolutioN (MAVEN) satellite observed CO first-negative band limb emission in the Martian…
A photochemical model of ultraviolet atomic line emissions in the inner coma of comet 67P/Churyumov-Gerasimenko
Susarla Raghuram, Anil Bhardwaj
Alice ultraviolet spectrometer onboard Rosetta space mission observed several spectroscopic emissions emanated from volatile species of comet 67P/Churyumov-Gerasimenko (hear after…
Atomic carbon, nitrogen, and oxygen forbidden emission lines in the water-poor comet C/2016 R2 (Pan-STARRS)
S. Raghuram, D. Hutsemékers, C. Opitom +3
The N and CO-rich and water-depleted comet C/2016 R2 (Pan-STARRS) (hereafter `C/2016 R2') is a unique comet for detailed spectroscopic analysis. We aim to explore the associate…
Prediction of forbidden ultraviolet and visible emissions in comet 67P/Churyumov-Gerasimenko
Susarla Raghuram, Anil Bhardwaj, Marina Galand
Remote observation of spectroscopic emissions is a potential tool for the identification and quantification of various species in comets. CO Cameron band (to trace \cod) and atomic…
Forbidden oxygen lines at various nucleocentric distances in comets
A. Decock, E. Jehin, P. Rousselot +5
To study the formation of the [OI] lines - i.e., 5577 A (the green line), 6300 A and 6364 A (the two red lines) - in the coma of comets and to determine the parent species of the o…
Photochemistry of atomic oxygen green and red-doublet emissions in comets at larger heliocentric distances
Susarla Raghuram, Anil Bhardwaj
In comets the atomic oxygen green to red-doublet emission intensity ratio (G/R ratio) of 0.1 has been used to confirm HO as the parent species producing oxygen emission lines.…
Model for Atomic Oxygen Visible Line Emissions in Comet C/1995 O1 Hale-Bopp
Susarla Raghuram, Anil Bhardwaj
We have recently developed a coupled chemistry-emission model for the green and red-doublet emissions of atomic oxygen on comet Hyakutake. In the present work we applied our model…
Coupled Chemistry-Emission Model for Atomic Oxygen Green and Red-doublet Emissions in Comet C/1996 B2 Hyakutake
Anil Bhardwaj, Susarla Raghuram
The green (5577 Å) and red-doublet (6300, 6364 Å) lines are prompt emissions of metastable oxygen atoms in the S and D states, respectively, that have been observed in seve…
Model for the Production of CO Cameron band emission in Comet 1P/Halley
Susarla Raghuram, Anil Bhardwaj
The abundance of CO2 in comets has been derived using CO Cameron band (a3pi --> X1Sigma+) emission assuming that photodissociative excitation of CO2 is the main production process…
Model for Cameron band emission in comets: A case for EPOXI mission target comet 103P/Hartley 2
Anil Bhardwaj, Susarla Raghuram
The CO2 production rate has been derived in comets using the Cameron band (a3Pi - X1Sigma) emission of CO molecule assuming that photodissociative excitation of CO2 is the main pro…
