Highly deuterated pre-stellar cores in a high-mass star formation region
F. Fontani, P. Caselli, T. L. Bourke +2
We have observed the deuterated gas in the high-mass star formation region IRAS 05345+3157 at high-angular resolution, in order to determine the morphology and the nature of such g…
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…
Searching for massive pre--stellar cores through observations of N2H+ and N2D+
F. Fontani, P. Caselli, A. Crapsi +4
We have measured the deuterium fractionation (through the column density ratio N(N2D+)/N(N2H+)) and the CO depletion factor (ratio between expected and observed CO abundance) in a…
Search for massive protostar candidates in the southern hemisphere: II. Dust continuum emission
Maria T. Beltran, Jan Brand, Riccardo Cesaroni +4
In an ongoing effort to identify and study high-mass protostellar candidates we have observed in various tracers a sample of 235 sources selected from the IRAS Point Source Catalog…
Search for massive protostellar candidates in the southern hemisphere: I. Association with dense gas
F. Fontani, M. T. Beltran, J. Brand +4
(Abridged) We have observed CS and C17O lines, and 1.2 mm cont. emission towards a sample of 130 high-mass protostellar candidates with DEC<-30 deg. This is the first step of the s…
Nature of two massive protostellar candidates: IRAs 21307+5049 and IRAS 22172+5549
F. Fontani, R. Cesaroni, L. Testi +4
We present observations of continuum and molecular lines towards the protostar candidates IRAS 21307+5049 and IRAS 22172+5549. Single-dish maps in the 12CO(2--1), C18O(2--1), HCO+(…
