A search for naphthalene in diffuse interstellar clouds

, 2011
We have obtained high resolution optical spectroscopy of 10 reddened O-type stars with UVES at VLT to search for interstellar bands of the naphthalene cation (C$_{10}$H$_{8}$$^+$) in the intervening clouds. No absorption features were detected near the laboratory strongest band of this cation at 6707 Åexcept for star HD 125241 (O9 I).

Unresolved velocity structure in diffuse interstellar clouds

The Astrophysical Journal, 1988
Recent high-resolution observations of interstellar absorption lines of CH and CN toward Zeta Oph obtained by Crane et al. (1986), and Palazzi et al. (1988), exhibit line widths that suggest thermal line broadening at high temperature, T about 1200 K.

Rotational equilibrium of C₂ in diffuse interstellar clouds

Astronomy & Astrophysics
Context. Recent spectroscopic measurements have revealed absorption from higher rotational levels in C2 than previous observations. These improvements are accompanied by the availability of updated radiative and collisional data. Aims. We revisit the density and radiation field intensity diagnostics provided by the observations of many rotational ...
