... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... Lightcurve of HW Vir from images obtained using the Faulkes Telescope South, operated by Las Cumbres Observatory . The blue triangles show the difference between two stars whose brightness is constant. ... This shows the value of the Faulkes Telescopes in the follow-up observations of eclipsing binaries with the aim to detect and characterise additional circumbinary companions. ...

... We present a computer program for modelling energy flux distribution and light curves of eclipsing binaries from far ultraviolet to infrared regions. The Roche model is assumed. Proximity effects of components (reflection of radiation and surface gravity darkening) are taken into account. ... Figure 1: The surface temperature distribution for Algol A-B system before (upper plot) and after (lower plot) correction for temperature due to the irradiation effect. ...

Peremennye Zvezdy ( Variable Stars ) 28 , No. ... I present the discovery of a pulsating component in light variations of the known eclipsing binary NSV 10993 based on the NSVS and ASAS-3 publicly available data. ... I re-analysed the NSVS and ASAS-3 data (NSVS 10974803, NSVS 11094130, and ASAS 183213+1217.1) using the WINEFK package by Dr. V.P. Goranskij and found pulsations superposing the eclipsing light curve. ... The eclipsing light curve is similar to the EB-type curves. ...

... In particular, members of the project regularly organize events dedicated to various interesting astronomical phenomena and events - solar and lunar eclipses, transit of Venus, etc. On November 3rd a team of astronomers will venture deep into Turkana National Park, Kenya and attempt to broadcast the magic of a total solar eclipse to the world. ... Solar eclipse . A solar eclipse occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks the Sun from our view. ...

... V838 Mon is a member of a new class of eruptive variables which appear as a peculiar novae having late K-M type spectra in their outburst. Before its outburst, it was a wide binary system of B3V type stars. ... The B3V companion was seen in the outburst in the UV spectrum taken with HST (Rauch et al., ... In the latest spectra, the light of B3V companion was predominating in the short-wave photometric bands. ... CCD blue frames of V838 Mon before the eclipse (left) and in the eclipse (right). ...
