  2. It is the distribution map of CS(J=1-0)49GHz in Orion A observed with the Nobeyama 45m Radio Telescope. In this observation, the region where density is still higher (hydrogen molecule density is about 10,000-100,000/cm3) can be seen rather than it sees by 13CO. It turns out that there are many lumps of small molecular clouds in the Orion A. When investigated based on the space distribution or the speed distribution, it turns out that there are the lump of about 100 molecule gas in this. A star is produced from the place (molecular cloud core) where such density increased. This is the first observation as a result of the molecular cloud core in the huge molecule clouds which produce a heavy star.
