Three-equation turbulent convection models in classical variables
Gábor B. Kovács, Róbert Szabó, János Nuspl
Context. Turbulent convection models in nonlinear radial stellar pulsation models rely on an extra equation for turbulent kinetic energy and fail to adequately explain mode-selecti…
A new framework of multidimensional pulsating stellar envelopes I.: Properties of turbulent convection in static RR Lyrae envelope models with SPHERLS
Gábor B. Kovács, R. Szabó, J. Nuspl
Context. The one-dimensional treatment of turbulent convection had large successes until the early 2000s. However, the recent abundance and precision of observational data shows th…
Temperature dependent convective parameters for RRc 1D-models
Gábor B. Kovács, János Nuspl, Róbert Szabó
Nonlinear pulsation modeling of classical variable stars is among the first topics which were developed at the beginning of the computational era. Various developments were made, a…
Calibration of the convective parameters in stellar pulsation hydrocodes
Gábor B. Kovács, Róbert Szabó, János Nuspl
Despite the appearance of two- and three-dimensional models thanks to the rapid growth of computing performance, numerical hydrocodes used to model radial stellar pulsations still…
Blazhko modulation in the infrared
J. Jurcsik, G. Hajdu, I. Dékány +3
We present first direct evidence of modulation in the -band of Blazhko-type RR Lyrae stars that are identified by their secular modulations in the I-band data of OGLE-IV. A meth…
Photometric and radial-velocity time-series of RR Lyrae stars in M3: analysis of single-mode variables
J. Jurcsik, P. Smitola, G. Hajdu +18
We present the first simultaneous photometric and spectroscopic investigation of a large set of RR Lyrae variables in a globular cluster. The radial-velocity data presented compris…
