Star Formation in Clusters: Subclustering, Cloud Fragmentation and the Origin of the Stellar IMF
Leonardo Testi
We review recent high spatial resolution millimeter continuum and spectral line observations of (proto-)cluster regions. These observations reveal that the mass distribution of pre…
The Onset of Cluster Formation around Intermediate Mass Stars
Leonardo Testi, Francesco Palla, Antonella Natta
We present the results of a recent near-infrared survey of the fields surrounding a large sample of intermediate-mass pre-main-sequence (Herbig Ae/Be) stars. While late-type Be and…
The onset of cluster formation around Herbig Ae/Be stars
L. Testi, F. Palla, A. Natta
The large body of near infrared observations presented in Testi et al. (1997; 1998) are analysed with the aim of characterizing the young stellar clusters surrounding Herbig Ae/Be…
A Multiwavelength Picture of the AFGL 5142 Star-forming Region
Todd R. Hunter, Leonardo Testi, Greg B. Taylor +3
We present molecular line, H2O maser, radio continuum and near infrared maps of the bipolar outflow source AFGL5142. The high resolution of our molecular CO observations enables us…
