Studying the molecular gas towards a bright rimmed cloud at the infrared
  dust bubble N30
  We present a study on the molecular gas towards a bright-rimmed cloud located
to the north of the infrared dust bubble N30. Using the emission from the 12CO,
13CO, and C18O J=3-2 line, together with infrared and radio continuum data, we
characterized the bubble and the related molecular cloud. In addition, we show
an analysis of the behaviour of the abundance ratio 13CO/C18O towards the
bright-rimmed cloud, and we search for clues on recent star-formation.
