The Chelgraph SGML Structured Editorld reverse the infall thus preventing further growth of the stellar mass. After illustrating the two models proposed to solve this problem (“accretion” and “coalescence”), we review the observational evidence pro/contra such models, focusing on rotating disk-like structures detected in association w

M. Woodman,D. Ince,J. Preece,G. Daviesmarkable progress toward understanding star formation due to advances in observational technology especially at infrared and millimeter wavelengths which allow direct observation of the sites of star birth. Such observations suggest that embedded clusters may be the fundamental units of star formati

Thomas H. Murray,Arthur L. Caplanture and to prepare for the observations with high angular resolution, we have studied the conditions of the plasma along a sample of ‘classical’ Herbig-Haro (HH) jets through a combined optical-infrared diagnostics. Here we present and discuss the results obtained for the HH 1 and HH 34 jets. We ap

“Suffer the Little Children ...”during a systematic search of the 2MASS database. The aim of our survey was to reobserve these objects with better spatial resolution and limiting magnitude. To date we have observed 25 of the 346 clusters found by Bica and Dutra (2003). We constructed near-IR color-color diagrams to identify PMS st
