Dynamical structure of the multiple stellar system HD164492

González, J. F.; Veramendi, M. E.

HD 164492 is a Trapezium-like stellar system with one O-type and several early B-type components immersed in an active star forming region (M20). The relevance of this system has increased after the recent discovery that one of its visual components, HD 164492C, is a spectroscopic triple with a remarkable magnetic field. As a complement of those s…

Búsqueda y análisis de asociaciones estelares en NGC247

Baume, G.; Rodríguez, M. J.; Feinstein, C.

From ACS/HST observations, available in the Space Telescope database, the search and analysis of young stellar associations in the galaxy NGC247 have been carried out. The Path Linkage Criterion was used for the detection, identifying 147 young stellar groups. Thanks to the ACS high spatial resolution, it was possible to detect the individual comp…

An outflow linked to a YSO in Gum 31?

Bosch, G.; Cappa, C. E.; Vazzano, M. M. +1 more

We analyze the distribution of the molecular gas associated with 10349-5824, a young stellar object located on the edge of the H ii region Gum31, with the aim of investigating the existence of bipolar outflows. We use CO(2-1) line observations obtained with the APEX telescope, H line observations on the K band taken with Flamingos 2 in Gemini Sout…
