| Abstract: |
Stars form out of dense cores in turbulent, magnetized molecular
clouds. However, the role of magnetic fields in star formation
remains poorly understood both theoretically and observationally.
This is in part due to the lack of the observational characterization
of the magnetic fields that are associated with the dense cores
prior to star formation, or pre-protostellar cores.
To shed light on the issue of the magnetic field in the gravitational
collapse of pre-protostellar cores, we have started a project of
the magnetic field measurements toward pre-protostellar cores
using the Zeeman splitting of CCS (JN = 43 – 32) line.
We are now developing a new 45GHz band, dual polarization, reciever
for the Nobeyama 45m telescope. In this contribution,
we summarize a current status of our Zeeman project and future plan. |
