Highlights on eclipsing binary variables from Araucaria Project
EPJ Web of Conferences, 2015 The Araucaria Project, which main goal is to provide precise determination of the cosmic distance scale, has recently made a set of discoveries involving variable stars in binary systems. Among these discoveries we highlight three: 1% precise measurement

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Research addressing the microfoundations of corporate social performance (CSP) in small and medium‐sized enterprises (SMEs) remains sparse. This paper aims to investigate how SME managers' ethical ideology affects CSP and examines the mediating role of their CSR orientation (CSRO): economic, legal, ethical, and philanthropic.

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

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.

Awe in nature fosters science identity and belonging in participatory scientists during an eclipse
People and Nature, EarlyView.Abstract The interactions between people and nature are complex, with research suggesting that people often report feeling awe in nature, including in relation to eclipses. Less is known about if feelings of awe in nature can drive science outcomes. The current study aimed to understand the relationship between observing a total eclipse in nature, awe ...

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

A Reflection Model for Eclipsing Binary Stars [PDF]
Monthly Notices of the Royal Astronomical Society, 1973 A highly accurate reflection model has been developed which emphasizes efficiency of computer calculation. It is assumed that the heating of the irradiated star must depend upon the following properties of the irradiating star: (1) effective temperature; (2) apparent area as seen from a point on the surface of the irradiated star; (3) limb darkening ...

KEPLER ECLIPSING BINARY STARS. VII. THE CATALOG OF ECLIPSING BINARIES FOUND IN THE ENTIRE KEPLER DATA SET [PDF]
The Astronomical Journal, 2016 ABSTRACT The primary Kepler Mission provided nearly continuous monitoring of ∼200,000 objects with unprecedented photometric precision. We present the final catalog of eclipsing binary systems within the 105 deg2 Kepler field of view. This release incorporates the full extent of the data from the primary mission (Q0-Q17
