Abstract:
The earliest evolutionary stages of low-mass protostars are
characterised by hot and fast jets which remove angular momentum
from the circumstellar disk, thus allowing mass accretion onto the
central object. However, the launch mechanism is still being debated.
We would like to exploit high-angular (∼0.8") resolution and
high-sensitivity images to investigate the origin of protostellar jets
using typical molecular tracers of shocked regions, such as SiO and
SO.
Description:
We mapped the inner 22" of the NGC1333-IRAS2A protostar in
SiO(5-4), SO(65-54), and the continuum emission at 1.4mm using
the IRAM Plateau de Bure interferometer in the framework of the
CALYPSO IRAM large program.
