ECLIPSING BINARY STARS : LIGHT CURVE MODELS AND SOFTWARE
Odessa Astronomical Publications, 2017 The importance of studying Eclipsing Binary Stars for the determination of fundamental stellar data is sketched. The eclipsing binaries, originally classified phenomenologically, are now understood on the basis of much firmer physics and the improved ...

A New Binary Star System of EW Type in Draco: GSC 03905-01870
, 2018 Discovery of a new binary star system (GSC 03905-01870 = USNO-B1.0 1431-0327922 = UCAC4 716-059522) in the Draco constellation is presented. It was discovered during a search for previously unreported eclipsing binary stars through the ASAS-SN database ...

THE AESTHETICS OF URBAN METABOLISM: Landscape, Design and the Politics of In/Visibility
International Journal of Urban and Regional Research, EarlyView.Abstract In this article, we chart the evolving aesthetic contours of urban metabolism across London, focusing on the River Lea and Thamesmead to the north and south of the River Thames, respectively. We begin in the nineteenth century, when these two sites formed critical nodes within a new sewerage system that relegated the city’s circulatory flows ...

Roberts of Lovedale and Eclipsing Binary Stars [PDF]
International Astronomical Union Colloquium, 1988 Alexander William Roberts, a great humanitarian and teacher in South Africa, was also a luminary in the astronomical world. This paper discusses his work on variable stars and touches briefly on his career in other areas. Born and educated in Scotland, Roberts migrated to South Africa in 1883, at age 25, to teach at the Native College at Lovedale.

Period change of massive binaries from combined photometric and spectroscopic data in Cygnus OB2
, 2015 Context. Mass loss is an important property in evolution models of massive stars. As up to 90% of the massive stars have a visual or spectroscopic companion and many of them exhibit mass exchange, mass-loss rates can be acquired through the period study ...

Eclipsing high-mass binary stars [PDF]
, 2014 Die Masse eines Sterns ist der maßgebende Parameter, der seine gesamte Entwicklung bestimmt. Massen von O-Sternen sind von besonderer Bedeutung, da sie die Hauptquellen von UV-Strahlung in der Galaxis sind und einen Großteil der schweren Elemente erzeugen. Damit spielen sie eine Schlüsselrolle in der Entwicklung unserer Galaxis.
