THE ABUNDANCES OF THE ELEMENTS OF THE MAGELLANIC CLOUDS
The results of the spectroscopic researches of classical Chepheids of the Magellanic Clouds (MC) are presented in this paper. 21 spec tra for the Large Magellanic Cloud (LMC) and 10 for the Small Magellanic Cloud (SMC) were investigated.

Discovery of 14 radio pulsars in a survey of the Magellanic Clouds [PDF]
A systematic survey of the Large and Small Magellanic Clouds for radio pulsars using the Parkes radio telescope and the 20-cm multibeam receiver has resulted in the discovery of 14 pulsars and the redetection of five of the eight previously known spin ...

The Parkes HI Survey of the Magellanic System [PDF]
We present the first fully and uniformly sampled, spatially complete HI survey of the entire Magellanic System with high velocity resolution, performed with the Parkes Telescope. The final data-cubes have an rms noise of sigma ~ 0.05 K and an effective angular resolution of 16 arcmin. The Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC)

Sub-millimeter to centimeter excess emission from the Magellanic Clouds. I. Global spectral energy distribution [PDF]
In order to reconstruct the global SEDs of the Magellanic Clouds over eight decades in spectral range, we combined literature flux densities representing the entire LMC and SMC respectively, and complemented these with maps extracted from the WMAP and ...

MACHO 311.37557.169: A VY Scl star
Abstract Optical surveys, such as the MACHO project, often uncover variable stars whose classification requires follow‐up observations by other instruments. We performed X‐ray spectroscopy and photometry of the unusual variable star MACHO 311.37557.169 with XMM‐Newton in April 2018, supplemented by archival X‐ray and optical spectrographic data.

Stellar dust production and composition in the Magellanic Clouds [PDF]
The dust reservoir in the interstellar medium of a galaxy is constantly being replenished by dust formed in the stellar winds of evolved stars. Due to their vicinity, nearby irregular dwarf galaxies the Magellanic Clouds provide an opportunity to obtain ...

Das Alter des Universums und der Sterne zu ermitteln, gehört seit jeher zu den zentralen Aufgaben der Astrophysik. Mittlerweile gibt es hierfür eine Vielzahl von Methoden. Einige liefern erstaunlich genaue Werte, andere sind unsicherer. Was also wissen wir heute und mit welcher Genauigkeit über das Alter von Sternen?

Supernova remnants in nearby galaxies
Abstract Supernova remnants (SNRs) are the aftermath of stellar explosions, which inject large amounts of energy into the interstellar medium (ISM), carving out new structures and transferring kinetic energy to the ISM. They also act as recycling centers, which return elements processed in stars to the ISM, and cosmic particle accelerators.

Pulsating stars in the VMC survey
The VISTA survey of the Magellanic Clouds system (VMC) began observations in 2009 and since then, it has collected multi-epoch data at Ks and in addition multi-band data in Y and J for a wide range of stellar populations across the Magellanic system ...
