IRAS 18153-1651: an H II region with a possible wind bubble blown by a young main-sequence B star
V. V. Gvaramadze, J. Mackey, A. Y. Kniazev +5
We report the results of spectroscopic observations and numerical modelling of the H II region IRAS 18153-1651. Our study was motivated by the discovery of an optical arc and two m…
Young Stellar Clusters Containing Massive Young Stellar Objects in the VVV Survey
J. Borissova, S. Ramírez Alegría, J. Alonso +17
The purpose of this research is to study the connection of global properties of eight young stellar clusters projected in the Vista Variables in the Via Lactea (VVV) ESO Large Publ…
Diagnostic of the unstable envelopes of Wolf-Rayet stars
Luca Grassitelli, Andre-Nicolas Chene', Debashis Sanyal +4
The envelopes of stars near the Eddington limit are prone to various instabilities. A high Eddington factor in connection with the Fe opacity peak leads to convective instability,…
GRACES observations of young [alpha/Fe]-rich stars
David Yong, Luca Casagrande, Kim A. Venn +10
We measure chemical abundance ratios and radial velocities in four massive (i.e., young) [alpha/Fe]-rich red giant stars using high-resolution high-S/N spectra from ESPaDOnS fed by…
