CN in prestellar cores
Pierre Hily-Blant, Malcolm Walmsley, G. Pineau Des Forêts +1
Determining the structure of and the velocity field in prestellar cores is essential to understanding protostellar evolution.} {We have observed the dense prestellar cores L 1544 a…
IRAS 18511+0146: a proto Herbig Ae/Be cluster?
S. Vig, L. Testi, M. Walmsley +3
Context: The evolution of a young protocluster depends on the relative spatial distributions and dynamics of both stars and gas. Aims: We study the distribution and properties of t…
Observing the gas temperature drop in the high-density nucleus of L 1544
Antonio Crapsi, Paola Caselli, Malcolm C. Walmsley +1
Abridged: The thermal structure of a starless core is crucial for our understanding of the physics in these objects and hence for our understanding of star formation. Theory predic…
Water in the envelopes and disks around young high-mass stars
Floris van der Tak, Malcolm Walmsley, Fabrice Herpin +1
Single-dish spectra and interferometric maps of (sub)mm lines of H2O-18 and HDO are used to study the chemistry of water in eight regions of high-mass star formation. The spectra i…
Molecular hydrogen formation on grain surfaces
S. Cazaux, P. Caselli, A. G. G. M. Tielens +2
We reconsider H2 formation on grain surfaces. We develop a rate equation model which takes into account the presence of both physisorbed and chemisorbed sites on the surface, inclu…
Polarized dust emission of magnetized molecular cloud cores
J. Goncalves, D. Galli, M. Walmsley
We compute polarization maps for molecular cloud cores modeled as magnetized singular isothermal toroids, under the assumption that the emitting dust grains are aspherical and alig…
