Radial velocity and light curves analysis of the eclipsing binary NN Vir

Odessa Astronomical Publications, 2017
The eclipsing binary NN Vir is a short period system showing an EW-type light curve. Photometric Observations of NN Vir were done by Gomez-Ferrellad & Garcia-Melendo (1997) at Esteve Duran Observatory.

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 ...

COMPARATIVE ANALYSIS OF NUMERICAL METHODS OF DETERMINATION OF PARAMETERS OF BINARY STARS. CASE OF SPHERICAL COMPONENTS

Odessa Astronomical Publications, 2013
We discuss methods for modeling eclipsing binary stars. There are few realizations of the Wilson- Devinney (1971) code and its improvements, e.g. “Binary Makef’, “Phoebe”. A parameter search using the Monte- Carlo method was realized by Zola et al. (2010)

Should more teams “trust the process” of tanking?

Contemporary Economic Policy, EarlyView.
Abstract In many professional sport leagues, the worst‐performing teams receive higher probability of earning top draft picks. This provides teams incentives to purposefully lose, or “tank,” if they are not likely to contend for the playoffs or championships.

Orbital Modulation Induced by a Third Component in the Overcontact Binary V0554 Dra

The Astrophysical Journal
We present the first comprehensive photometric and spectroscopic analysis of the overcontact eclipsing binary V0554 Dra. By simultaneously modeling multiband light curves and radial velocity data using the Wilson–Devinney code, we determine that the ...
