A Spectroscopic Survey of WNL Stars in the LMC: General Properties and Binary Status
O. Schnurr, A. F. J. Moffat, N. St-Louis +2
We report the results of an intense, spectroscopic survey of all 41 late-type, nitrogen-rich Wolf-Rayet (WR) stars in the Large Magellanic Cloud (LMC) observable with ground-based…
Multiple and Precessing Collimated Outflows in the Planetary Nebula IC 4634
M. A. Guerrero, L. F. Miranda, A. Riera +6
With its remarkable double-S shape, IC 4634 is an archetype of point-symmetric planetary nebulae (PN). In this paper, we present a detailed study of this PN using archival HST WFPC…
Kinematical Analysis of a Sample of Bipolar Planetary Nebulae
Martina Dobrincic, Eva Villaver, Martin A. Guerrero +1
We present the kinematics of a sample of bipolar planetary nebulae (PNe) which cover a wide range of observed morphologies and collimation degrees, from bipolar PNe with a marked e…
An X-ray Survey of Wolf-Rayet Stars in the Magellanic Clouds. I. The Chandra ACIS Dataset
Martin A. Guerrero, You-Hua Chu
Wolf-Rayet (WR) stars are evolved massive stars with strong fast stellar winds. WR stars in our Galaxy have shown three possible sources of X-ray emission associated with their win…
An X-ray Survey of Wolf-Rayet Stars in the Magellanic Clouds. II. The ROSAT PSPC and HRI Datasets
Martin A. Guerrero, You-Hua Chu
Wolf-Rayet (WR) stars in the Magellanic Clouds (MCs) are ideal for studying the production of X-ray emission by their strong fast stellar winds. We have started a systematic survey…
The H2 Amazing Life of NGC 6881
G. Ramos-Larios, M. A. Guerrero, L. F. Miranda
The H2 and optical (Ha, [NII]) morphology of NGC 6881 are very different. Here we present a preliminary report of the analysis of new optical (Ha and [NII]) and near-IR (Brg and H2…
