A Galactic O2 If*/WN6 star possibly ejected from its birthplace in NGC3603
Alexandre Roman-Lopes
In this work I report the discovery of a new Galactic O2 If*/WN6 star, a rare member of the extremely massive hydrogen core-burning group of stars that due its high intrinsic lumin…
Southern near-infrared photometric monitoring of Galactic young star clusters (NIP of Stars)
R. Barbá, N. Morrell, G. Gunthardt +8
We have performed a near-infrared photometric monitoring of 39 galactic young star clusters and star-forming regions, known as {\em NIP of Stars}, between the years 2009--2011, usi…
The young stellar cluster [DBS2003] 157 associated with the H II region GAL 331.31-00.34
Marcio C. Pinheiro, Zulema Abraham, Marcus V. F. Copetti +3
We report a study of the stellar content of the Near-infrared cluster [DBS2003]\,157 embedded in the extended H\,{\sc ii} region GAL\,331.31-00.34, which is associated with the IRA…
A young stellar cluster within the RCW41 HII region: deep NIR photometry and Optical/NIR polarimetry
Fábio P. Santos, Alexandre Roman-Lopes, Gabriel A. P. Franco
The RCW41 star-forming region is embedded within the Vela Molecular Ridge, hosting a massive stellar cluster surrounded by a conspicuous HII region. Understanding the role of inter…
