Early stages of cluster formation: fragmentation of massive dense cores down to ~1000 AU
Aina Palau, Asunción Fuente, Josep M. Girart +11
In order to study the fragmentation of massive dense cores, which constitute the cluster cradles, we observed with the PdBI in the most extended configuration the continuum at 1.3…
Interferometric mapping of the 3.3-mm continuum emission of comet 17P/Holmes after its 2007 outburst
J. Boissier, D. Bockelée-Morvan, N. Biver +4
Comet 17P/Holmes underwent a dramatic outburst in October 2007, caused by the sudden fragmentation of its nucleus and the production of a large quantity of grains scattering sunlig…
Observations of the 18-cm OH lines of comet 103P/Hartley 2 at Nançay in support to the EPOXI and Herschel missions
Jacques Crovisier, Pierre Colom, Nicolas Biver +2
The 18-cm radio lines of the OH radical were observed in comet 103P/Hartley 2 with the Nançay radio telescope in support to its flyby by the EPOXI mission and to observations with…
Ammonia and other parent molecules in comet 10P/Tempel 2 from Herschel/HIFI and ground-based radio observations
N. Biver, J. Crovisier, D. Bockelée-Morvan +13
The Jupiter-family comet 10P/Tempel 2 was observed during its 2010 return with the Herschel Space Observatory. We present here the observation of the (J, K) = (1, 0)-(0, 0) transit…
