The XO Planetary Survey Project - Astrophysical False Positives

, 2010
Searches for planetary transits find many astrophysical false positives as a by-product. There are four main types analyzed in the literature: a grazing-incidence eclipsing binary star, an eclipsing binary star with a small radius companion star, a blend

The binary properties of the pulsating subdwarf B eclipsing binary PG 1336-018 (NY Virginis) [PDF]

, 2007
Aims. We present an unbiased orbit solution and mass determination of the components of the eclipsing binary PG1336−018 as a critical test for the formation scenarios of subdwarf B stars. Methods. We obtained high-resolution time series VLT/UVES spectra

Multiparametric Bioresorbable Sensor for Doxorubicin Detection via Molecularly Imprinted Synthetic Receptors

Advanced Science, EarlyView.
A biodegradable molecularly imprinted polymer porous silica sensor enables dual optical readout of doxorubicin via fluorescence and effective optical thickness shifts. The combined transduction mechanisms provide enhanced reliability and quantitative accuracy over clinically relevant concentrations, representing a step toward transient implantable ...

Modelling of W UMa-type variable stars

South African Journal of Science, 2009
W Ursae Majoris (W UMa)-type variable stars are over-contact eclipsing binary stars. To understand how these systems form and evolve requires observations spanning many years, followed by detailed models of as many of them as possible.

KM UMa: An Active Short-period Detached Eclipsing Binary in a Hierarchical Quadruple System

The Astrophysical Journal
The first detailed photometric and spectroscopic analysis of the G-type eclipsing binary KM UMa is presented, which indicates that the system is a short-period detached eclipsing binary.

Precision photometry with difference imaging in the WTS

EPJ Web of Conferences, 2013
The Wide Field Camera Transit Survey is a pioneer program aimed to search for extra-solar planets in the near-infrared. The standard data reduction pipeline of the program uses aperture photometry to construct the light curves. We alternatively apply the

VW LMi: tightest quadruple system known. Light-time effect and possible secular changes of orbits

, 2008
Tightest known quadruple systems VW LMi consists of contact eclipsing binary with P_12 = 0.477551 days and detached binary with P_34 = 7.93063 days revolving in rather tight, 355.0-days orbit.

The eclipsing, double-lined, Of supergiant binary Cyg OB2-B17 [PDF]

, 2010
Massive, eclipsing, double-lined, spectroscopic binaries are not common but are necessary to understand the evolution of massive stars as they are the only direct way to determine stellar masses.

Notes on the spectra of eclipsing binaries.

The Astronomical Journal, 1950
The writer is engaged in a program of observing eclipsing binaries with the principal aim of obtaining masses and radii of stars of various types. For this purpose it is necessary that radial velocities of both components of a system be obtained.
