Open Research EuropeAs we learn more about the multi-scale interstellar medium (ISM) of our Galaxy, we develop a greater understanding for the complex relationships between the large-scale diffuse gas and dust in Giant Molecular Clouds (GMCs), how it moves, how it is ...

Isomerism of CH2SO: Accurate structural, energetic, and spectroscopic characterization
Journal of Computational Chemistry, Volume 45, Issue 11, Page 777-786, April 30, 2024.What is the next sulfur‐containing molecule that will be detected in space? Guided by the experimental data on the cis‐/trans‐HC(O)SH conformers, the structural and spectroscopic properties of cis‐/trans‐HC(S)OH have been accurately determined using state‐of‐the‐art quantum‐chemical approaches. Abstract A recent work [Ye et al. Mon. Not. R. Astron. Soc.

ON THE GF-VALUES FOR SOME DIATOMIC MOLECULAR SPECTRA
Odessa Astronomical Publications, 2017 In view of rich structure of the energy levels and the variety of transition types which are observable, molecules are the useful tool for investigation of physical parameters of stellar atmospheres, interstellar and circumstellar matter.

Are young supernova remnants interacting with circumstellar gas
The Astrophysical Journal, 1982 The young remnants of galactic Type I supernovae (SN 1006, SN 1572, and SN 1604) appear to be interacting with moderately dense gas (n/sub O/> or =0.1 cm/sup -3/). If the gas in the ambient interstellar medium, the observations suggest that gas of this density is fairly pervasive.

CIRCUMSTELLAR ACTIVITY OF THE HERBIG AE STAR HD163296
Odessa Astronomical Publications, 2007 We present new results of a high-resolution spectroscopic investigation of the young Ae Herbig star HD163296. Nineteen spectra of this object had been obtained on May 8 - 10, 2002 at the ESO with the FEROS echelle spectrometer installed at the 1.52m ...

Carbon but No CO? Circumstellar Gas Absorption in FUV Spectra of the Unusual 49 Ceti Debris Disk [PDF]
, 2014 We present the first high-resolution HST-STIS FUV spectra of the nearby A1V star 49 Ceti. The system is famous for harboring a circumstellar disk that shows the dust properties of a debris disk, but the gas properties of a low-mass protoplanetary disk ...
