    Observation of a variable, ZZ Ceti white dwarf: GD154
    The ZZ Ceti stars form a class of variable white dwarfs: the hydrogen dominated atmosphere ones, which do pulsate in an instability strip in the effective...

    On the Metamorphosis of the Bailey Diagram for RR Lyrae Stars
    We collected over 6000 high-resolution spectra of four dozen field RR Lyrae (RRL) variables pulsating either in the fundamental (39 RRab) or in the first...

    On the relation of the Duvall phase function to the upper layers on the convection zone
    A method to obtain the Duvall phase function from the structure of a stellar model is presented. This can be a good tool for understanding the dependence of p...
