Cometary nuclei contain the least modified material from the formative epoch of our
planetary system, and their compositions reflect a range of processes experienced by …

Our main knowledge about astrophysical environments relies on radiative spectra.
Absorption studies require background sources that are located hapharzadly in …

Context. The ESA Rosetta spacecraft (S/C) is tracking comet 67P/Churyumov-Gerasimenko
in close vicinity. This prolonged encounter enables studying the evolution of the volatile …

Comets spend most of their lives at large distances from any star, during which time their
interior compositions remain relatively unaltered. Cometary observations can therefore …

Line strengths have been calculated in the form of Einstein A coefficients and f-values for a
large number of bands of the A 2 Π–X 2 Σ+ and B 2 Σ+–X 2 Σ+ systems and rovibrational …

Optical emission of laser-produced plasmas from solids, liquids, and gases, from their
fundamentals to their potential applications, has been comprehensively reported in multiple …

The activity of most comets near the Sun is dominated by the sublimation of frozen water, the
most abundant ice in comets. Some comets, however, are active well beyond the water-ice …

Cyanogen (NCCN) is the simplest member of the series of dicyanopolyynes. It has been
hypothesized that this family of molecules can be important constituents of interstellar and …

It is thought that dicyanopolyynes could potentially be abundant interstellar molecules;
though, their lack of a dipole moment makes it impossible to detect them through …

The line intensities of the fundamental rotational transitions of H13CN and HC15N were
observed towards two prestellar cores, L183 and L1544, and lead to molecular isotopic …
