Effects of Metallicity on the Rotation Rates of Massive Stars

, 2004
Recent theoretical predictions for low metallicity massive stars predict that these stars should have drastically reduced equatorial winds (mass loss) while on the main sequence, and as such should retain most of their angular momentum.

VLT/UVES Observations of Interstellar Molecules and Diffuse Bands in the Magellanic Clouds

, 2006
We discuss the abundances of interstellar CH, CH+, and CN in the Magellanic Clouds (MC), derived from spectra of 7 SMC and 13 LMC stars obtained (mostly) with the VLT/UVES.

Distance scale calibration based on early-type binaries

EPJ Web of Conferences, 2017
Our main goal is to establish a firm empirical calibration of the surface brightness vs. (V-K) color relation for early type stars based on high quality spectroscopic and infrared observations of early-type detached eclipsing systems in the Large ...

Modeling CO, CO$_2$ and H$_2$O ice abundances in the envelopes of young stellar objects in the Magellanic Clouds

, 2018
Massive young stellar objects in the Magellanic Clouds show infrared absorption features corresponding to significant abundances of CO, CO$_2$ and H$_2$O ice along the line of sight, with the relative abundances of these ices differing between the ...

Ages of Large Magellanic Cloud Star Clusters with Gemini Multi-Object Spectrograph Integrated Spectroscopy: Systematic Comparison of Available Tools

The Astronomical Journal
We present the first systematic analysis comparing the ages, reddening, and radial velocities of star clusters using two widely used tools: STARLIGHT and Analyzer of Spectra for Age Determination (A.S.A.D). Both tools utilize the full integrated spectrum

The Small Magellanic Cloud [PDF]

Symposium - International Astronomical Union, 1959
In 1957 a two-year photometric study of the Small Magellanic Cloud, sponsored by Indiana University and supported by the National Science Foundation was completed. Six region swere investigated. They are three on the edge of the SMC centered on conspicuous star clusters and three nearer the center.

The chemical DNA of the Magellanic Clouds

Astronomy & Astrophysics
In this study we investigate the chemical enrichment of the rapid neutron-capture process in the Small Magellanic Cloud (SMC). We measured the [Eu/Fe] abundance ratio of 209 giant stars that are confirmed members of the SMC, providing the first extensive
