A new framework of multidimensional pulsating stellar envelopes Open
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 that this problem is far from solved. Even so, ongoing theore…

Estimation of Classical Cepheid's Physical Parameters from NIR Light Curves Open
Recent space-borne and ground-based observations provide photometric measurements as time series. The effect of interstellar dust extinction in the near-infrared range is only 10% of that measured in the V band. However, the sensitivity of…

Similar additional frequency patterns on fundamental- and overtone-mode RR Lyrae stars showing <i>f</i><sub>68</sub> frequencies Open
Context. Until now, it has been accepted that the additional frequencies in the fundamental-(RRab) and overtone-mode pulsating (RRc and RRd) RR Lyrae stars are of a different nature. RRab stars show frequencies associated with periodic dou…

Similar additional frequency patterns on fundamental and overtone mode RR Lyrae stars showing $f_{68}$ frequencies Open
Up to now, it seemed that the additional frequencies in the fundamental mode (RRab) and in the overtone mode pulsating (RRc and RRd) RR Lyrae stars have different nature. RRab stars show frequencies associated with periodic doubling, as we…
