Four New Delta Scuti Pulsators from a Variability Survey of 131 Stars [PDF]
Publications of the Astronomical Society of the Pacific, 2002 In a photometric variability survey of 131 stars with B < 14 mag, we have found four new Delta Scuti stars. We were sensitive to oscillation amplitudes as low as a few mmag.

Incidence of High-Amplitude δ Scuti-Type Variable Stars [PDF]
Publications of the Astronomical Society of Japan, 2008 Abstract An order-of-magnitude estimate for the incidence of high-amplitude $\delta$ Scuti-type variable stars (HADS) in the $\delta$Scuti area of the H-R diagram was calculated. Using a model for the stellar distribution in the Milky Way, we calculated the number of stars that are expected to fall in the $\delta$Scuti area of the H-R ...

FREQUENCY ANALYSIS OF DELTA SCUTI VARIABLE STARS. I.
Odessa Astronomical Publications, 2017 The Fourier analyses are performed for photoelectric observations of two δ Scuti stars V567 Oph and KU Cen. It is shown that V567 Oph is a multiperiodic star and KU Cen has one main period.

The TAOS Project Stellar Variability I. Detection of Low-Amplitude delta Scuti Stars [PDF]
, 2009 We analyzed data accumulated during 2005 and 2006 by the Taiwan-American Occultation Survey (TAOS) in order to detect short-period variable stars (periods of

The ASAS-SN catalogue of variable stars VI: an all-sky sample of δ Scuti stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT 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 the fundamental mode and overtone pulsators in the WJK, V, Gaia DR2 G, J, H, Ks, and W1 bands.

Highlights of Discoveries for δ Scuti Variable Stars From the Kepler Era [PDF]
Frontiers in Astronomy and Space Sciences, 2021 The NASAKeplerand follow-on K2 mission (2009–2018) left a legacy of data and discoveries, finding thousands of exoplanets, and also obtaining high-precision long time-series data for hundreds of thousands of stars, including many types of pulsating variables.

Variability Analysis of δ Scuti Candidate Stars [PDF]
Publications of the Astronomical Society of the Pacific, 2018 The Hipparcos catalog contains stars suspected to be {\delta} Scuti variables for which extensive ground-based observations and characterization of variability are necessary. Our aim was to characterize variability of 13 candidates to {\delta} Scuti type stars.

Spectroscopy of a chemically peculair delta scuti-type star: 60 tau
Cumhuriyet Science Journal, 2020 In this study, a detailed spectroscopic analysis of 60 Tau is presented. 60 Tau is a Delta Scuti-type pulsating variable and it is also a metallic-lined (Am) star.

TESS Observations of Seven Newly Identified High-amplitude δ Scuti Stars
The Astrophysical Journal, 2023 We report seven newly identified high-amplitude δ Scuti (HADS) stars. Among them, two stars (TIC 30977864 and TIC 387379145) exhibit pure radial pulsation without the excitation of non-radial modes.
