The Origins of Young Stars in the Direction of the Leading Arm of the Magellanic Stream: Abundances, Kinematics, and Orbits
(2019)
We explore the origins of the young B-type stars found by Casetti-Dinescu et al. at the outskirts of the Milky Way disk in the sky region of the Leading Arm of the Magellanic Stream. High-resolution spectroscopic observations ...
A three-decade outburst of the LMC luminous blue variable R127 draws to a close
(IOP Publishing, 2008-12)
The paradigmatic luminous blue variable R127 in the Large Magellanic Cloud has been found in the intermediate, peculiar early-B state, and substantially fainter in visual light, signaling the final decline from its major ...
Chemical Composition of Young Stars in the Leading Arm of the Magellanic System
(2017)
Chemical abundances of eight O-and B-type stars are determined from high-resolution spectra obtained with the MIKE instrument on the Magellan. 6.5 m Clay telescope. The sample is selected from 42 candidates for membership ...
GEMINI/GMOS search for massive binaries in the ionizing cluster of 30 DOR
(IOP Publishing, 2009-12)
If binaries are common among massive stars, it will have important consequences for the derivation of fundamental properties such as the cluster age, initial mass function, and dynamical mass. Making use of the multiplexing ...
Spectrophotometric data of the central star of the large Magellanic Cloud planetary nebula N66: Quantitative analysis of its WN-type spectrum
(1997-12-10)
Hubble Space Telescope, IUE, and ground-based observations of the central star of the LMC planetary
nebula N66 (CS N66), obtained in di†erent epochs, are presented. Since 1990, CS N66 has displayed
remarkable short- and ...
