We have carried out observations of a peculiar comet, C/2016 R2 (Pan-STARRS), using a low-resolution spectrograph mounted on the 1.2-m telescope at Mount Abu Infrared Observatory, India. The comet was observed on two dates in 2018 January, when it was at a heliocentric distance of 2.8 au. A study based on our observations has revealed that the optical spectrum of this comet is quite unusual compared with general cometary spectra. Most major cometary emissions, such as C2, C3 and CN, were…

A physico-chemical model to study the ion density distribution in the inner coma of comet C/2016 R2 (Pan-STARRS)
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 distance. Assuming solar
Knowledge Gaps in the Cometary Spectra of Oxygen-bearing Molecular Cations
Molecular cations are present in various astronomical environments, most notably in cometary atmospheres and tails where sunlight produces exceptionally bright near-UV to visible transitions. Such

The extraordinary composition of the blue comet C/2016 R2 (PanSTARRS)
We present a multi-wavelength study of comet C/2016 R2 (PanSTARRS). This comet was observed on 23 and 24 January 2018 with the IRAM 30 m telescope, and in January to March 2018 with the Nançay radio
Strong CO+ and Emission in Comet C/2016 R2 (Pan-STARRS)*
We report on imaging and spectroscopic observations of comet C/2016 R2 (Pan-STARRS) obtained with the 0.8 m and 2.7 m telescopes of McDonald Observatory in 2017 November and December, respectively.
High resolution optical spectroscopy of the N2-rich comet C/2016 R2 (PanSTARRS)
Context. Early observations of comet C/2016 R2 (PanSTARRS) have shown that the composition of this comet is very peculiar. Radio observations have revealed a CO-rich and HCN-poor comet and an optical
The Peculiar Volatile Composition of CO-dominated Comet C/2016 R2 (PanSTARRS)
Comet C/2016 R2 (PanSTARRS) has a peculiar volatile composition, with CO being the dominant volatile as opposed to H$_2$O and one of the largest N$_2$/CO ratios ever observed in a comet. Using
Optical spectroscopy of comet C/2014 Q2 (Lovejoy) from the Mount Abu Infrared Observatory
Spectra of comet C/2014 Q2 (Lovejoy) were taken with a low resolution spectrograph mounted on the 0.5 m telescope at the Mount Abu Infrared Observatory (MIRO), India during January to May 2015
C/2016 R2 (PANSTARRS): A Comet Rich in CO and Depleted in HCN
We observed comet C/2016 R2 (PANSTARRS) with the ARO 10-m SMT, and report the first detection of CO emission from this comet with amounts high enough to be the primary driver of activity. We obtained
A Search for N2+ in Spectra of Comet C/2002 C1 (Ikeya-Zhang)
We report low- and high-resolution spectra of comet C/2002 C1 (Ikeya-Zhang) from the McDonald Observatory. The comet has a well-developed ion tail including CO+, CO, CH+, and H2O+. We used our
A High Spectral Resolution Atlas of Comet 122P/de Vico
Abstract On 3 and 4 October 1995, we obtained high spectral resolving power (R=λ/Δλ=60,000) observations of Comet 122P/de Vico using the 2DCoude cross-dispersed echelle spectrograph on the 2.7-m
Cometary activity of distant object C/2002 VQ94 (LINEAR)
Aims. We have started a program of spectroscopic and photometric investigations of distant active comets in the optical domain. The comets with a significant level of activity–in particular, extended
