      Aslan, Zeki (İstanbul Kültür Üniversitesi Yayınları, 2005)
      Türkiye'de amatör astronom ve amatör astronomi kulüplerinin sayisi hizla artmaktadir. Biribirleri ile astronominin hemen her dalinda elektronik ortamda tartismakta, astronomi bilgilerini gelistirmektedirler. En önemlisi ...
    • Kinematics of M-type giant semi-regular variables from the Hipparcos catalogue 

      Aslan, Zeki; Yeşilyaprak, Cahit (CSIRO PUBLISHING, 150 OXFORD ST, PO BOX 1139, COLLINGWOOD, VICTORIA 3066, AUSTRALIA, 2008)
      The kinematics of M-type (O-rich) giant semi- regular (SR) variable stars were examined. They were grouped with respect to their relative parallax errors (epsilon(pi)/pi) in order to study the stars having relatively better ...
    • Optical Counterpart Positions Of Extragalactic Radio Sources And Connecting Optical And Radio Reference Frames 

      Aslan, Zeki; Gumerov, R.; Jin, W.; Khamitov, I.; Maigurova, N.; Pinigin, G.; Tang, Z.; Wang, S. (Edp Sciences S A, 17, Ave Du Hoggar, Pa Courtaboeuf, Bp 112, F-91944 Les Ulis Cedex A, France, 2010-02)
      We discuss the results of an investigation of astrometric positions of extragalactic radio sources from a list for the International Celestial Reference Frame. About 300 fields around extragalactic radio sources were ...
    • Optical observations of the galactic supernova remnants G59.5+0.1, G84.9+0.5 and G67.7+1.8 

      Gok, F.; Sezer, A.; Aslan, Zeki (Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2008-12)
      We present here the optical CCD observations and long slit spectra of the galactic supernova remnants G59.5+0.1, G84.9+0.5 and G67.7+1.8, the first two being observed for the first time. The observations were carried out ...
    • Position Observations of NEAs at the RTT150 

      Aslan, Zeki; Ivantsov, Anatoliy V.; Gumerov, Rustem I.; Hudkova, Lyudmila A.; Khamitov, Irek; Pinigin, Gennadiy I. (Amer Inst Physics, 2 Huntington Quadrangle, Ste 1No1, Melville, Ny 11747-4501 USA, 2008)
      In 2004-2007, 560 observations of 17 Near-Earth Asteroids of 15-21 magnitudes were made at the Russian-Turkish telescope (RTT150). The reduction was made using reference stars from the UCAC2 and USNO-B1 catalogues. The ...
