The potential of photometric methods for the identification of l, the degree of spherical
surface harmonic of a pulsating star, is investigated with special emphasis on Stromgren …

We present the results of multisite observations of the δ Scuti star V 1162 Ori. The
observations were done in the period October 1999-May 2000, when 18 telescopes at 15 …

A 16-inch Schmidt-Cassegrain telescope on the campus of Naresuan University of Thailand
and several similar-size telescopes in China equipped with CCD cameras were used to …

We present a comprehensive investigation of the variations of period and amplitude in the
high-amplitude δ Scuti star AE UMa based on our new Johnson V time-series …

The results obtained by means of the photometric approach to the study of Delta Sct stars
are extensively discussed. The different frequency contents of the three best candidates for …

We report that the intermediate amplitude δ Scuti star V 1162 Ori has changed its main
pulsational period in the course of the year 2000. This new period change falls in a …

In most Delta Scuti stars, the measured period changes are considerably larger than those
expected from stellar evolution. In order to study these period and amplitude changes, a few …

ABSTRACT GSC 2985‐01044 is a δ Scuti star with a period of 0.0933584 days and a V‐
magnitude range of 11.85–12.05; its light curve is slightly variable. The location, space …

We present yb time-series CCD photometry of the high-amplitude delta Scuti star V 1162 Ori.
A period break and a significant decrease in amplitude (50 percent) has been reported for …

The hk index has been used as a metallicity indicator for RR Lyrae variable stars. It is now
being applied to the shorter period δ Scuti variables. Employing spectroscopic abundances …
