  • Ammonia molecule and its applications in astrophysics 
    Polinovskyi, G.; Pavlenko, Ya.V.; Tennyson, J.; Yurchenko, S.N.; Barber, R.J. (Advances in Astronomy and Space Physics, 2012)
    Recently a new ammonia line list BYTe was reported comprising more than 1.1 billion transitions and designed for temperatures up to 1500 K. In this study we present an application of this line list for modelling spectra ...

    Choliy, V. (Advances in Astronomy and Space Physics, 2012)
    This issue of Advances in Astronomy and Space Physics (AASP) represents the new-born "thick" scientific journal. Our aim is to be a broadcast platform for those young scientists who work in astronomy, astrophysics, space ...
  • Binary evolution pulsating star - new evolutionary channel to produce RR Lyr-like pulsations 
    Karczmarek, P. (Advances in Astronomy and Space Physics, 2012)
    In 2011 a promising candidate for an RR Lyrae star in an eclipsing binary system was found. Till that time not even one case of RR Lyrae star in a binary system has been known. The pulsator's mass is 0.26 Mꙩ which is not ...
  • Catalogue-atlas of photographic observations along Comet Liller's path

    We present the on-line version of the catalogue-atlas of photographic observations along the path of comet Liller (1988a). The comet was observed in the N. D. Kalinenkov Astronomical Observatory (AOK) of the Nikolaev ...
  • CCD photometry of some areas around the open cluster M45 
    Savushkin, A.A.; Shlyapnikov, A.A. (Advances in Astronomy and Space Physics, 2012)
    We present the results of photometric studies in some areas around the open star cluster M 45. Observations were carried out on January-March 2012. About 600 images were obtained in the V band (Johnsons system). Centres ...
  • CCD VRI photometry of the old open cluster NGC 7142 
    Punanova, A.F.; Loktin, A.V.; Krushinsky, V.V.; Popov, A.A. (Advances in Astronomy and Space Physics, 2012)
    Photometry of 2194 stars in the field of the open cluster NGC 7142 in VRI filters was performed to search variable stars. Eleven probable variable stars were found using robust median statistics. We separated probable ...

  • Centaurus A as a plausible source of ultra high energy cosmic rays registered by the Pierre Auger Observatory 
    Sushchov, O.B.; Kobzar, O.O.; Hnatyk, B.I.; Marchenko, V.V. (Advances in Astronomy and Space Physics, 2012)
    For ultra high energy cosmic rays events detected by the Pierre Auger Observatory which arrive from the region near Centaurus A the positions of the corresponding sources were calculated for the two chosen galactic magnetic ...
  • Chandra observations of ten galaxy clusters 
    Babyk, Iu.; Melnyk, O.; Elyiv, A. (Advances in Astronomy and Space Physics, 2012)
    In the present study the X-ray properties of 10 galaxy clusters (CL0024+17, RXJ1347.5+1145, A223, A521, A611, A697, A907, A1204, A1413 and A2744) are analysed using the archival X-ray data of the Chandra observatory. The ...
  • Circumsubstellar disk SED in dependence on system parameters 
    Zakhozhay, O. (Advances in Astronomy and Space Physics, 2012)
    Formulae for critical angles and areas that permit to imagine configurations of observed systems and to calculate their spectral energy distributions (SEDs) as dependencies on their geometrical parameters and inclination ...
  • Coronal jet contribution to the slow Solar wind flux: preliminary results 
    Paraschiv, A.R.; Dragomirescu, D.; Stan, L.; Talpeanu, D.C.; Ivan, C.; Radu, S.; Lacatus, D.A.; Mierla, M. (Advances in Astronomy and Space Physics, 2012)
    The solar wind is a continuous flux of charged particles that are ejected from the Sun's atmosphere. The sources of this flux have not been clearly identiffed yet. Coronal jets are proposed as a possible candidate. They ...
  • Criteria for galaxy classification in SDSS 
    Dobrycheva, D.; Melnyk, O. (Advances in Astronomy and Space Physics, 2012)
