Searching for active low-mass stars in CMa star-forming region: multi-band photometry with T80S
J. Gregorio-Hetem, F. Navarete, A. Hetem +10
An exotic environment surrounds the young stellar groups associated with the Canis Major (CMa) OB1/R1 region, which probably was formed under feedback from at least three supernova…
Star formation history of Canis Major OB1 - II. A bimodal X-ray population revealed by XMM-Newton
T. Santos-Silva, J. Gregorio-Hetem, T. Montmerle +2
The Canis Major OB1 Association has an intriguing scenario of star formation, especially in the Canis Major R1 (CMa R1) region traditionally assigned to a reflection nebula, but in…
Statistical fractal analysis of 25 young star clusters
J. Gregorio-Hetem, A. Hetem, T. Santos-Silva +1
A large sample of young stellar groups is analysed aiming to investigate their clustering properties and dynamical evolution. A comparison of the Q statistical parameter, measured…
Characterization of Young Stellar Clusters
T. Santos-Silva, J. Gregorio-Hetem
A high number of embedded clusters is found in the Galaxy. Depending on the formation scenario, most of them can evolve to unbounded groups that are dissolved within a few tens of…
Probing the anomalous extinction of four young star clusters: the use of colour-excess, main sequence fitting and fractal analysis
B. Fernandes, J. Gregorio-Hetem, A. Hetem
Four young star clusters were studied in order to characterize their anomalous extinction or variable reddening that could be due to a possible contamination by dense clouds or cir…
Star formation history of CMa R1: I. Wide-field X-ray study of the young stellar population
J. Gregorio-Hetem, T. Montmerle, C. V. Rodrigues +3
The CMa R1 star-forming region contains several compact clusters as well as many young early-B stars. It is associated with a well-known bright rimmed nebula, the nature of which i…
