    • What Powers the 2006 Outburst of the Symbiotic Star BF Cygni? 

      Autor: Skopal, A.; Sekeráš, M.; Tomov, N. A.; Tomova, M. T.; Tarasova, T. N.; Wolf, M.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      BF Cygni is a classical symbiotic binary. Its optical light curve occasionally shows outbursts of the Z And-type, whose nature is not well understood. During the 2006 August, BF Cyg underwent the recent outburst, and ...

    • When a Nova Becomes Old 

      Autor: Ederoclite, A.; Tappert, C.; Schmidtobreick, L.; Vogt, N.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Here we present the preliminary results of a project aimed at unveiling the nature of classical novae decades after their eruption. The ultimate goal of this project is to describe the population of cataclysmic variables ...

    • White Dwarfs in Cataclysmic Variables: An Update 

      Autor: Sion, E. M.; Godon, P.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      In this review, we summarize what is currently known about the surface temperatures of accreting white dwarfs in nonmagnetic and magnetic cataclysmic variables (CVs) based upon synthetic spectral analyses of far ultraviolet ...

    • Who Discovered the Hoyle Level? 

      Autor: Shaviv, G.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      The prediction of Hoyle that the nucleus of 12C must have a resonance at 7.62MeV was the trigger to the Anthropic Principle. We review the history of the discovery of this level and investigate to what extent this was a ...

    • Why a New Code for Novae Evolution and Mass Transfer in Binaries? 

      Autor: Shaviv, G.; Idan, I.; Shaviv, N. J.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      One of the most interesting problems in Cataclysmic Variables is the long time scale evolution. This problem appears in long time evolution, which is also very important in the search for the progenitor of SN Ia. The ...

    • X-Ray Observations of VY Scl-Type Nova-Like Binaries in the High and Low State 

      Autor: Zemko, P.; Orio, M.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Four VY Scl-type nova-like systems were observed in X-rays both during the low and the high optical states. They are BZ Cam, MV Lyr, TT Ari, and V794 Aql. Using archival ROSAT, Swift and SUZAKU observations we found that ...
