Optical Spectra of Radio Planetary Nebulae in the Small Magellanic Cloud [PDF]

Serbian Astronomical Journal, 2008
We present preliminary results from spectral observations of four (4) candidate radio sources co-identified with known planetary nebulae (PNe) in the Small Magellanic Cloud (SMC).

The period distribution of Cepheids: a test of stellar evolution

EPJ Web of Conferences, 2015
The period distributions of classical Cepheids in the Small and Large Magellanic Cloud are quite different. Using the TRILEGAL population synthesis code and a theoretical instability strip the ultimate aim is to understand these differences ...

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 ...

Properties of Anomalous and Type II Cepheids in the Small and Large Magellanic Clouds

EPJ Web of Conferences, 2017
The Small Magellanic Cloud (SMC) and Large Magellanic Cloud (LMC) give us the possibility to study individual variable star types in a new way. Literature data provide us with photometric information about objects from the ultraviolet to the infrared ...

Massive runaway stars in the Small Magellanic Cloud [PDF]

, 2010
Using archival Spitzer Space Telescope data, we identified for the first time a dozen runaway OB stars in the Small Magellanic Cloud (SMC) through the detection of their bow shocks.

A High-resolution Imaging Survey of Massive Young Stellar Objects in the Magellanic Clouds

The Astrophysical Journal
Constraints on the binary fraction of massive young stellar objects (mYSOs) are important for binary and massive star formation theory. Here, we present speckle imaging of 34 mYSOs located in the Large Magellanic Cloud (1/2 Z _⊙ ) and Small Magellanic ...

A bright millisecond radio burst of extragalactic origin

, 2007
Pulsar surveys offer one of the few opportunities to monitor even a small fraction (~0.00001) of the radio sky for impulsive burst-like events with millisecond durations.

Testing the effects of opacity and the chemical mixture on the excitation of pulsations in B stars of the Magellanic Clouds [PDF]

, 2012
The B-type pulsators known as \beta Cephei and Slowly Pulsating B (SPB) stars present pulsations driven by the \kappa mechanism, which operates thanks to an opacity bump due to the iron group elements.

HEAD IN THE STARS, FEET ON THE GROUND: Scale and Astronomy Initiatives in Southern Africa

Cultural Anthropology, Volume 40, Issue 4, Page 571-596, November 2025.
ABSTRACT This article explores the evolution of radio astronomy in South Africa and Madagascar, focusing on how “scale” functions as both a way of understanding the world and marking differences in existence. In outer space research, the ground is crucial but often overlooked.

On a possible origin for the lack of old star clusters in the Small Magellanic Cloud [PDF]

, 2013
We model the dynamical interaction between the Small and Large Magellanic Clouds and their corresponding stellar cluster populations. Our goal is to explore whether the lack of old clusters ($\gtrsim 7$ Gyr) in the Small Magellanic Cloud (SMC) can be the
