    We present the results of our comparison of three main numerical ephemerides (DELE, INPOP, EPM) for the determination of precision and errors of their dynamical coordinate systems. It was shown that all of them have ...
  • On the question of detecting granulation signal in CoRoT light curves of A and B stars 
    Ghazaryan, S. (Advances in Astronomy and Space Physics, 2013)
    We applied the procedure written by us to HgMn targets observed both through CoRoT astero and exo channels to check its usefulness for search of possible existence of solar-type granulation signature in their power spectrum. ...
  • Optical observations of selected asteroids with measurable Yarkovsky effect 
    Pomazan, A.V.; Maigurova, N.V. (Advances in Astronomy and Space Physics, 2013)
    The results of the observations of 10 asteroids for 2009-2012 and their analysis are presented here. The asteroids were selected based on the available list of asteroids with relatively large deviations from the unperturbed ...
  • Photometric observations of Epsilon Aurigae during the eclipse of 2009-2011 
    Iłkiewicz, K.; Wychudzki, P.; Gałan, C.; Gładkowski, M.; Dobierski, P.; Karska, A.; Więcek, M.; Tomov, T.; Mikołajewski, M. (Advances in Astronomy and Space Physics, 2013)
    Epsilon Aurigae is a bright binary system, in which an F0 supergiant is eclipsed by a dark disk around the companion, every 27.1 years. Although the star has been observed and studied for nearly two centuries, it remains ...
  • Power spectra of convective motions in the solar photosphere 
    Baran, O.A. (Advances in Astronomy and Space Physics, 2013)
    We reproduced the convective velocity field and the temperature structure of the solar photosphere using neutral iron line λ ≈ 639.3 nm profiles from the observations with high spatial resolution taken around the centre ...
  • Stochastic scattering in Cen A radio lobes
