Orion's Bar: Physical Conditions across the Definitive H+ / H0 / H2 Interface
E. W. Pellegrini, J. A. Baldwin, G. J. Ferland +2
Previous work has shown the Orion Bar to be an interface between ionized and molecular gas, viewed roughly edge on, which is excited by the light from the Trapezium cluster. Much o…
Electron temperature fluctuations in NGC 346
V. A. Oliveira, M. V. F. Copetti, A. C. Krabbe
The existence and origin of large spatial temperature fluctuations in HII regions and planetary nebulae are assumed to explain the differences between the heavy element abundances…
Kinematics and physical properties of Southern interacting galaxies: the minor merger AM 2306-721
A. C. Krabbe, M. G. Pastoriza, Claudia Winge +2
We present an observational study about the effects of the interactions in the kinematics, stellar population and abundances of the components of the galaxy pair AM2306-721. Rotati…
The qWR star HD 45166. II. Fundamental stellar parameters and evidence of a latitude-dependent wind
J. H. Groh, A. S. Oliveira, J. E. Steiner
The enigmatic object HD 45166 is a qWR star in a binary system with an orbital period of 1.596 day, and presents a rich emission-line spectrum in addition to absorption lines from…
