The N2D+/N2H+ ratio as an evolutionary tracer of Class 0 protostars
M. Emprechtinger, P. Caselli, N. H. Volgenau +2
Deuterated ions are abundant in cold (T=10 K), dense (n=10^5 cm^-3) regions, in which CO is frozen out onto dust grains. In such environments, the deuterium fractionation of such i…
The Photon Dominated Region in the IC 348 molecular cloud
K. Sun, V. Ossenkopf, C. Kramer +4
In this paper we discuss the physical conditions of clumpy nature in the IC 348 molecular cloud. We combine new observations of fully sampled maps in [C I] at 492 GHz and 12CO 4--3…
Structure analysis of interstellar clouds: II. Applying the Delta-variance method to interstellar turbulence
V. Ossenkopf, M. Krips, J. Stutzki
The Delta-variance analysis is an efficient tool for measuring the structural scaling behaviour of interstellar turbulence in astronomical maps. In paper I we proposed essential im…
Structure analysis of interstellar clouds: I. Improving the Delta-variance method
V. Ossenkopf, M. Krips, J. Stutzki
The Delta-variance analysis, has proven to be an efficient and accurate method of characterising the power spectrum of interstellar turbulence. The implementation presently in use,…
Submillimeter Line Emission from LMC N159W: a Dense, Clumpy PDR in a Low Metallicity Environment
J. L. Pineda, N. Mizuno, J. Stutzki +30
Star formation at earlier cosmological times takes place in an interstellar medium with low metallicity. The Large Magellanic Cloud (LMC) is ideally suited to study star formation…
