Dynamics of surface steps
F. Szalma, W. Selke, S. Fischer
In the framework of SOS models, the dynamics of isolated and pairs of surface steps of monoatomic height is studied, for step--edge diffusion and for evaporation kinetics, using Mo…
The 2000 outburst of the recurrent nova CI Aquilae: optical spectroscopy
L. L. Kiss, J. R. Thomson, W. Ogloza +2
We present low- and medium resolution spectra of the recurrent nova CI Aquilae taken at 14 epochs in May and June, 2000. The overall appearance is similar to other U Sco-type recur…
Spectrophotometry and period analysis of the sdB eclipsing binary HW Virginis
L. L. Kiss, B. Csak, K. Szatmary +2
New CCD observations of the pre-cataclysmic binary HW Virginis are presented and discussed. The R-filtered CCD photometry was supplemented with medium-band (Cousins VRI) spectropho…
The chiral WZNW phase space as a quasi-Poisson space
J. Balog, L. Feher, L. Palla
It is explained that the chiral WZNW phase space is a quasi-Poisson space with respect to the `canonical' Lie quasi-bialgebra which is the classical limit of Drinfeld's quasi-Hopf…
Multiperiodicity in semiregular variables II. Systematic amplitude variations
L. L. Kiss, K. Szatmary, Gy. Szabo +1
We present a detailed lightcurve analysis for a sample of bright semiregular variables based on long-term (70--90 years) visual magnitude estimates carried out by amateur astronome…
Griffiths-McCoy singularities in random quantum spin chains: Exact results through renormalization
Ferenc Igloi, Robert Juhasz, Peter Lajko
The Ma-Dasgupta-Hu renormalization group (RG) scheme is used to study singular quantities in the Griffiths phase of random quantum spin chains. For the random transverse-field Isin…
