We present new photometric data for seven high-amplitude delta Scuti stars. The observations were acquired between 1996 and 2002, mostly in the Johnson photometric system. For one star (GW UMa), our observations are the first since the discovery of its pulsational nature from the Hipparcos data.The primary goal of this project was to update our knowledge on the period variations of the target stars. For this, we have collected all available photometric observations from the literature and… 
Pulsations of the High-Amplitude δ Scuti star YZ Bootis
We present a study on pulsations of the high-amplitude δ Scuti star YZ Boo based on photometric observations in Johnson V and R bands with both the Nanshan 1-m telescope of Xinjiang Astronomical
A cool stellar companion to the δ Scuti variable star GW UMa
Abstract GW UMa is a new high-amplitude δ Scuti variable star with a period of 0 d . 20319367 . By using a few new determined times of light maximum together with those collected from the literature,
Binarity and multiperiodicity in high-amplitude δ Scuti stars
We have carried out a photometric and spectroscopic survey of bright high-amplitude δ Scuti (HADS) stars. The aim was to detect binarity and multiperiodicity (or both) in order to explore the
Observations and Orbital Analysis of the High-Amplitude Delta Scuti Star SZ Lyncis: The Unusual Orbital Precession
We determined forty-two new times of light maximum from our photometry observations and WASP project, and collected all times of light maximum observed between 1961 and 2013 in order to calculate the
On the period variations of several low declination high amplitude delta Scuti variables
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 observe 14 high amplitude
The first high-amplitude δ Scuti star in an eclipsing binary system
We report the discovery of the first high-amplitude δ Scuti star in an eclipsing binary, which we have designated UNSW-V-500. The system is an Algol-type semi-detached eclipsing binary of maximum
Stability in Period and Amplitude: The High-Amplitude δ Scuti Star YZ Boötis
The variability of period and amplitude of the high-amplitude δ Scuti star YZ Boo was thoroughly investigated based on a comprehensive analysis of new time-series photometry and other available data.
Mass Loss from Red Giant Stars in Globular Clusters
Mass loss plays a significant role in stellar evolution. The stellar wind of a red giant star is many times stronger than that of a main sequence star. These stars can be found in great numbers in
The period variation of DY Hercules
Abstract In this paper the researchers collected 28 times of maximum light including 4 times of those observed at the Xinglong station, the National Astronomical Observation of China between May 27,
We measure two new times of light maximum of the SX Phoenicis star DY Pegasi in 2008 December and collect 410 pe/CCD times of light maximum that had been published. These data could be modeled with a


A photometric monitoring of bright high-amplitude δ Scuti stars - I. The double-mode pulsation of V567 Ophiuchi
We present the first results of an observational project, which addresses the period changing behaviour of a sample of high-amplitude Scuti stars. In this paper we discuss the double-mode nature of
The multimode pulsation of the δ Scuti star V784 Cassiopeae
We present an analysis of new Johnson and Stromgren photometric and medium-resolution spectroscopic observa- tions of the δ Scuti type variable star V784 Cassiopeae. The data were obtained in three
Determination of physical parameters of five large amplitude delta Scuti stars
photometry of the large amplitude δ Scuti stars BP Peg, DY Peg, DY Her, CY Aqr and YZ Boo is presented. Since the data were obtained almost simultaneously in all filters, meaningful physical
Studies of Large‐Amplitude δ Scuti Variables. III. DY Pegasi*
This is the third in a series of papers on large-amplitude δ Scuti and related stars intended to determine Baade-Wesselink radii and luminosities with precision. The first two papers discussed our
Stability in the Light Curves of High‐Amplitude δ Scuti Stars: Selected Monoperiodic Stars
We have analyzed all the reliable photometric data sets available in the bibliography for a selected sample of monoperiodic high-amplitude δ Scuti stars in order to study the stability of their light
Amplitude and Period Changes in the SX Phoenicis Star XX Cygni
The new time-resolved CCD photometry of XX Cyg was presented. We investigate the time-dependent behaviour of the light variations by reanalyzing the data in the literature. XX Cyg was demonstrated
The Type Ia Supernova 2001V in NGC 3987
CCD photometry is presented of the type Ia SN 2001V occurred in the edge-on spiral galaxy NGC 3987. The observations made through Johnson-Cousins BVRI filters were collected from Feb. 24 (t = -8
