Physical conditions in PDRs revealed by IGRINS ro-vibrational H2 observations

Aurélien Piluso, Vincent Maillard, Raphael Meshaka +10

We compare H2 high ro-vibrational observations of 5 PDRs (S140, IC63, Horsehead Nebula, NGC 2023 and Orion Bar) obtained with the IGRINS spectrograph to PDR models produced with th…

Chemical diversity of dense cores in Orion B: The role of the environment

Helena J. Mazurek, Maryvonne Gerin, Pierre Gratier +26

Prestellar cores are the sites of the earliest stages of star formation. Dust continuum observations are often used to identify and characterize their properties yet only a small f…

Tracers of the ionization fraction in dense and translucent molecular gas: II. Using mm observations to constrain ionization fraction across Orion B

Ivana Bešlić, Maryvonne Gerin, Viviana V. Guzmán +28

The ionization fraction () is a crucial parameter of interstellar gas, yet estimating it requires deep knowledge of molecular gas chemistry…

Estimating the dense gas mass of molecular clouds using spatially unresolved 3 mm line observations

Antoine Zakardjian, Annie Hughes, Jérôme Pety +28

We aim to develop a new method to infer the sub-beam probability density function (PDF) of H2 column densities and the dense gas mass within molecular clouds using spatially unreso…

Toward a robust physical and chemical characterization of heterogeneous lines of sight: The case of the Horsehead nebula

Léontine Ségal, Antoine Roueff, Jérôme Pety +28

Dense cold molecular cores/filaments are surrounded by an envelope of translucent gas. Some of the low-J emission lines of CO and HCO isotopologues are more sensitive to the co…

Quantifying the informativity of emission lines to infer physical conditions in giant molecular clouds. I. Application to model predictions

Lucas Einig, Pierre Palud, Antoine Roueff +29

Observations of ionic, atomic, or molecular lines are performed to improve our understanding of the interstellar medium (ISM). However, the potential of a line to constrain the phy…
