Phosphorus-bearing molecules in solar-type star-forming regions: first PO detection [PDF]

, 2016
Based on observations carried out as part of the Large Program ASAI (project number 012-12) with the IRAM 30 m telescope. IRAM is supported by INSU/CNRS (France), MPG (Germany) and IGN (Spain).

Dynamical evolution of star-forming regions - II. Basic kinematics [PDF]

, 2016
We follow the dynamical evolution of young star-forming regions with a wide range of initial conditions and examine how the radial velocity dispersion, $\sigma$, evolves over time.

Sulphur abundance determinations in star-forming regions - I. Ionization correction factor [PDF]

, 2016
In the present work we used a grid of photoionization models combined with stellar population synthesis models to derive reliable Ionization Correction Factors (ICFs) for the sulphur in star-forming regions.

The Dependence of Star Formation Efficiency on Gas Surface Density

, 2013
Studies by Lada (2010) and Heiderman (2010) have suggested that star formation mostly occurs above a threshold in gas surface density Sigma of Sigma_c = 120 Msun pc^{-2} (A_K = 0.8). Heiderman infer a threshold by combining low-mass star-forming regions,

Looking for outflow and infall signatures in high mass star forming regions

, 2011
(Context) Many physical parameters change with time in star forming regions. Here we attempt to correlate changes in infall and outflow motions in high mass star forming regions with evolutionary stage using JCMT observations.

Star forming regions of the southern galaxy [PDF]

A catalog of southern dust cloud properties is being compiled to aid in the planning and analysis of radio spectral line surveys in the southern hemisphere. Ultimately, images of dust temperature and column density will be produced.
