Eclipsing Binary Stars from Space [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractWe have begun a programme to obtain high-precision photometry of bright detached eclipsing binary (dEB) stars with the Wide-field InfraRed Explorer (WIRE) satellite (Bruntt & Buzasi 2006). Due to the small aperture of WIRE, only stars brighter than V = 6 can be observed.

The eclipsing binary star RZ Cas [PDF]
Astronomy & Astrophysics, 2003 In a first report on the results of a multi-site campaign in 2001 of photometric and spectroscopic observations of the active semi-detached Algol-type system RZ Cas, we concentrate on the radial velocity (RV) variations. Using weak absorption lines we obtain an improved orbital solution for both components.

Wide binary stars in the Galactic field : a statistical approach [PDF]
, 2010 This thesis focuses on the statistical properties of wide binary (WB) star systems in the Galactic field. With projected separations larger than 200 AU and, consequently, having very low binding energies, WB are sensitive probes of the Galactic ...

The Mass and Angular Momentum Relation of Eclipsing Binaries [PDF]
Journal of Astronomy and Space Sciences, 1998 With a total 3780 eclipsing binary system in the Catalogue of Approximate Photometric and Absolute Elements of Eclipsing Variable Stars by Svechnikov & Kuznetsova (1990), the empirical relations between the systemic mass and orbital angular momentum have

The Surface Brightness-color Relations Based on Eclipsing Binary Stars: Toward Precision Better than 1% in Angular Diameter Predictions [PDF]
, 2017 In this study we investigate the calibration of surface brightness–color (SBC) relations based solely on eclipsing binary stars. We selected a sample of 35 detached eclipsing binaries with trigonometric parallaxes from Gaia DR1 or Hipparcos whose ...

Hidden Companions Detected by Asteroseismology. I. Two Kepler Field Non-Eclipsing Binaries
Universe, 2022 The Kepler space telescope has detected a large number of variable stars. We summarize 2261 δ Scuti and hybrid variables in the literature, and perform time-frequency analysis on these variable stars. Two non-eclipsing binary systems, KIC 5080290 and KIC

A Note on the Physical Quantities of Eclipsing Binary Stars [PDF]
, 2016 publisherIn the research activities of high school students, they derive the period of luminosity variation from the light curve of eclipsing binary stars and often consider the aspects of the eclipsing binary stars in phenomenological terms. In addition

Asteroseismology of Eclipsing Binary Stars [PDF]
, 2014 Eclipsing binaries have long served as benchmark systems to measure fundamental properties of stars. In recent decades, asteroseismology—the study of stellar pulsations—has emerged as a powerful new tool to study the structure and evolution of stars across the H–R diagram.

Ten eclipsing binaries in the Small Magellanic Cloud: fundamental parameters and Cloud distance [PDF]
, 2003 We present the first results of an observational programme to measure the fundamental parameters of over 100 eclipsing binaries in the Small Magellanic Cloud (SMC).

CEACAM1 participation in breast cancer progression
Molecular Oncology, EarlyView.In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.
