A new Bok globule towards Cygnus OB2 No. 12

Show Summary Details


The NH3(1, 1) line emission was detected at −120 arcsec, + 60 arcsec offset from the star Cyg OB2 No. 12. The region had been initially mapped in 13CO(1 –0) and was called clump B. The subsequent detection of the CS(2 –1) line by the same authors led them to suggest that the clump could be an object similar to a Bok globule. The present detection and analysis confirm what was proposed before, that is clump B is a newly discovered starless Bok globule.
