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 role of carbon grains in the deuteration of H2
S. Cazaux, P. Caselli, V. Cobut +1
Aims: The production of molecular hydrogen and its deuterated forms onto carbonaceous dust grains is investigated in detail. The goal of this study is to estimate the importance of…
The IC1396N proto-cluster at a scale of 250 AU
R. Neri, A. Fuente, C. Ceccarelli +7
We investigate the mm-morphology of IC1396N with unprecedented spatial resolution to analyze its dust and molecular gas properties, and draw comparisons with objects of similar mas…
Comparative study of complex N- and O-bearing molecules in hot molecular cores
F. Fontani, I. Pascucci, P. Caselli +3
We have observed several emission lines of two Nitrogen-bearing (C2H5CN and C2H3CN) and two Oxygen-bearing (CH3OCH3 and HCOOCH3) molecules towards a sample of well-known hot molecu…
An Observational Perspective of Low-Mass Dense Cores I: Internal Physical and Chemical Properties
J. Di Francesco, N. J. Evans, P. Caselli +4
Low-mass dense cores represent the state of molecular gas associated with the earliest phases of low-mass star formation. Such cores are called "protostellar" or "starless," depend…
First detection of [CII]158um at high redshift: vigorous star formation in the early universe
R. Maiolino, P. Cox, P. Caselli +10
We report the detection of the 2P_3/2 -> 2P_1/2 fine-structure line of C+ at 157.74 micron in SDSSJ114816.64+525150.3 (hereafter J1148+5251), the most distant known quasar, at z=6.…
