We present statistical characteristics of 1578 δ Scuti stars including nearby field stars and cluster member stars within the Milky Way. We obtained 46% of these stars (718 stars) from work by Rodríguez and collected the remaining 54% of stars (860 stars) from other literature. We updated the entries with the latest information of sky coordinates, color, rotational velocity, spectral type, period, amplitude, and binarity. The majority of our sample is well characterized in terms of typical… 

LAMOST views δ Scuti pulsating stars

About 766 delta Scuti stars were observed by LAMOST by 2017 June 16. Stellar atmospheric parameters of 525 variables were determined, while spectral types were obtained for all samples. In the paper,

The ASAS-SN catalogue of variable stars VI: an all-sky sample of δ Scuti stars

We characterize an all-sky catalogue of ∼8400 δ Scuti variables in ASAS-SN, which includes ∼3300 new discoveries. Using distances from Gaia DR2, we derive period–luminosity relationships for both

Catalogue and Properties of δ Scuti Stars in Binaries

The catalogue contains 199 confirmed cases of binary systems containing at least one pulsating component of {\delta} Scuti type. The sample is divided into subgroups in order to describe the

Detection of a large sample of γ Doradus stars from Kepler space photometry and high-resolution ground-based spectroscopy

The space-missions MOST, CoRoT, and Kepler deliver a huge amount of high-quality photometric data suitable to study numerous pulsating stars. Our ultimate goal is a detection and analysis of an

We present photometric and spectroscopic follow-up observations of short-period variables discovered in the OmegaWhite survey: a wide-field high-cadence g-band synoptic survey targeting the Galactic

Eclipsing binary stars with a δ Scuti component

Eclipsing binaries with a $\delta$ Sct component are powerful tools to derive the fundamental parameters and probe the internal structure of stars. In this study, spectral analysis of 6 primary

THE CHEMICAL COMPOSITION OF ρ PUPPIS AND THE SIGNS OF ACCRETION IN THE ATMOSPHERES OF B–F-TYPE STARS

We investigated the chemical composition of ρ Pup using high-resolution spectral observations taken from the Very Large Telescope and the IUE archives and also spectra obtained at the 1.8 m telescope

Spectroscopic and photometric studies of a candidate pulsating star in an eclipsing binary: V948 Her

Eclipsing binary stars with a pulsating component are powerful tools that allow us to probe the stellar interior structure and the evolutionary statuses with a good accuracy. Therefore, in this

The high-amplitude δ Scuti variable CY Aqr is probably a triple system

Data representing 864 times of light maxima of the high-amplitude δ Scuti star CY Aqr were collected from the literature, based on which, long-term period changes of the variable star were

The OmegaWhite Survey for short period variable stars - II. An overview of results from the first four years

OmegaWhite is a wide-field, high cadence, synoptic survey targeting fields in the southern Galactic plane, with the aim of discovering short period variable stars. Our strategy is to take a series of
