Abstract:
Due to the short timescales involved and observational difficulties,
our knowledge of the earliest phases of massive star formation remains
incomplete. We aim to explore the physical conditions during the
initial phases of high-mass star formation and to detect a genuine
massive (mass M>8M☉) protostar at an early evolutionary stage.
Description:
The observations were obtained at the Plateau de Bure Interferometer
(PdBI) in from January to March 2005. The PdBI observations made use
of the facility receivers and backends with resolutions of 40kHz
(HCO+(1-0)), 160kHz (CO(2-1)), and 2.5MHz (1 and 3mm continuum, 500MHz
bandwidth). Phase calibrators were 2200+420 and 0059+581, and
additional amplitude calibrators were MWC349, 3C84, 3C273, 1928+738,
2037+511, and 0212+735. The sky opacity during the observations was
approximately tau=0.2 (at 230GHz) and the system temperatures
Tsys∼400K (230GHz) and Tsys∼150K (89GHz).
The fits files show (channel) maps of ISOSS J23053+5953 with the flux
