▪ Abstract Stars over essentially the whole mass domain can become pulsationally unstable
during various stages of their evolution. They will appear as variable stars with …

Having been operational at Kitt Peak for more than a year, the prototype (HAT‐1) of the
Hungarian Automated Telescope (HAT) has been used for an all‐sky variability search of …

The Blazhko effect is a long-term, generally irregular modulation of the light curves that
occurs in a sizeable number of RR Lyrae stars. The physical origin of the effect has been a …

We report the discovery of RV Tauri stars in the Large Magellanic Cloud (LMC). In light-and
color-curve behavior, the RV Tauri stars appear to be a direct extension of the type II …

A programme of photometric and spectroscopic observations has been undertaken in order
to investigate the physical characteristics of the RV Tauri variables. This paper presents and …

Resonances or near resonances are ubiquitous among the excited nonradial pulsation
modes of variable stars and they must play an important role in determining their pulsational …

Nonlinear Analysis of the Light Curve of the Variable Star R Scuti ADS Classic is now
deprecated. It will be completely retired in October 2019. This page will automatically redirect to …

The discipline of nonlinear dynamics has developed explosively in all areas of physics over
the last two decades. This comprehensive primer summarizes the main developments in the …

Close binary stars are binary stars where the component stars are close enough such that
they can exchange mass and/or energy. They are subdivided into semidetached …

Chaotic time series data are now commonly observed in a large variety of fields. The
analysis of such time series and the extraction of physical information is therefore a topic of …
