  • The influence of stellar wind bubbles on the ionizing radiation field in HII regions 
    Koshmak, I.O.; Melekh, B.Ya. (Advances in Astronomy and Space Physics, 2012)
    Stellar wind around starbursts forms cavities filled by hot gas with low density, thermalized by inverse wind shock. Young starbursts can contain the compact cavities inside Hii region. Diffuse ionizing radiation, that ...
  • The luminosity - spectral index dependence of the X-ray bright Seyfert galaxies 
    Sadova, V.A.; Tugay, A.V. (Advances in Astronomy and Space Physics, 2015)
    X-ray luminosities and spectral indices of 97 bright Seyfert 1 (Sy1) galaxies from the XMM-Newton archive are analysed in this article. Distribution of these values is random, so we conclude that the model of emission ...

    We present the photometric investigation of the newly discovered magnetic cataclysmic variable (polar) 1RXS J184542 during four months in 2012. We used the CCD observations in R-band obtained with the 0.5-m ARCSAT telescope ...
  • Transit timing at Torun Center for Astronomy 
    Bykowski, W.; Maciejewski, G. (Advances in Astronomy and Space Physics, 2011)
    The transit monitoring is one of well-known methods for discovering and observing new extrasolar planets. Among various advantages, this way of searching other worlds does not require complex and expensive equipment - it ...
  • Trapped fast MGD waves in dayside magnetosphere 
    Voshchepynets, A.; Agapitov, O. (Advances in Astronomy and Space Physics, 2012)
    We studied the dynamics of the magnetosphere response to the solar wind parameters changes using the Alfvén velocity distribution in the Earth's magnetosphere obtained from the IGRF and T89 Earth's magnetic field models ...
  • Two-period variability of the intermediate polar FO Aqr 
    Breus, V.V.; Andronov, I.L.; Hegedus, T.; Dubovsky, P.A.; Kudzej, I. (Advances in Astronomy and Space Physics, 2012)
