GEMINI near-infrared spectroscopic observations of young massive stars embedded in molecular clouds
A. Roman-Lopes, Z. Abraham, R. Ortiz +1
K-band spectra of young stellar candidates in four southern hemisphere clusters have been obtained with the near-infrared spectrograph GNIRS in Gemini South. The clusters are assoc…
The young massive stellar cluster associated to RCW121
Alexandre Roman-Lopes, Zulema Abraham
We report NIR broad and narrow band photometric observations in the direction of the IRAS17149-3916 source that reveal the presence of a young cluster of massive stars embedded in…
The true nature of the alleged planetary nebula W16-185
Alexandre Roman-Lopes, Zulema Abraham
We report the discovery of a small cluster of massive stars embedded in a NIR nebula in the direction of the IRAS15411-5352 point source, which is related to the alleged planetary…
The stellar population associated with IRAS source 16132-5039
Alexandre Roman Lopes, Zulema Abraham
We report the discovery of a young massive stellar cluster and infrared nebula in the direction of the CS molecular cloud associated to the IRAS point source 16132-5039. The analys…
Discovery of a young massive stellar cluster associated with IRAS source 16177-5018
Alexandre Roman-Lopes, Zulema Abraham, Jacques Raymond Daniel Lepine
We report the discovery of a young massive stellar cluster embedded in an extended HII region, invisible at optical wavelengths where the extinction is magnitudes,…
