Two papers recently reported the detection of gaseous nickel and iron in the comae of over 20 comets from observations collected over two decades, including interstellar comet 2I/Borisov. To evaluate the state of the laboratory data in support of these identifications, we reanalyzed archived spectra of comet C/1996 B2 (Hyakutake), one of the nearest and brightest comets of the past century, using a combined experimental and computational approach. We developed a new, many-level fluorescence… 


FeI and NiI in cometary atmospheres
FeI and NiI emission lines have recently been found in the spectra of 17 Solar System comets observed at heliocentric distances between 0.68 and 3.25 au and in the interstellar comet 2I/Borisov. The
Iron and nickel atoms in cometary atmospheres even far from the Sun.
It is reported that neutral Fe I and Ni I emission lines are ubiquitous in cometary atmospheres, even far from the Sun, as revealed by high-resolution ultraviolet-optical spectra of a large sample of comets of various compositions and dynamical origins.
Gaseous atomic nickel in the coma of interstellar comet 2I/Borisov.
Spectroscopic observations of atomic nickel vapour in the cold coma of 2I/Borisov at a heliocentric distance of 2.322 astronomical units are reported, in line with the recent identification of this atom-as well as iron-in the cold comae of Solar System comets17.
The NH and CH Bands of Comet C/1996 B2 (Hyakutake)
Abstract Comet Hyakutake was an ideal target for studying the near-nuclear region of a bright comet. On 1996 March 26.3–26.5 (UT) we observed the comet with an echelle spectrometer at the 4-m
Unidentified Molecular Bands in the Plasma Tail of Comet Hyakutake (C/1996 B2)
Unidentified molecular emission bands first observed in optical spectra of the plasma tail of comet Halley (1P/1982 U1) have been discovered in pure ion tail spectra (Δλ~4700-6300 A, λ/Δλ~1000-4400)
Composition and radiative properties of grains in molecular clouds and accretion disks
We define a model of the compositon and abundances of grains and gases in molecular cloud cores and accretion disks around young stars by employing a wide range of astronomical data and theory, the

Atomic Data for Resonance Absorption Lines. II. Wavelengths Longward of the Lyman Limit for Heavy Elements
This compilation extends the 1991 listing of atomic data by Morton to the heavier stable elements from germanium to bismuth. Technetium, thorium, and uranium are added because they can live long
Elemental and molecular abundances in comet 67P/Churyumov-Gerasimenko
Comets are considered to be some of the most pristine and unprocessed Solar system objects accessible to in situ exploration. Investigating their molecular and elemental composition takes us on a
