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 δ Scuti variables for which extensive ground-based observations and characterization of variability are necessary. Our aim was to characterize variability of 13 candidates to δ Scuti type stars. We obtained 24 215 CCD images and analyzed stellar light curves using the Period04 program. Twelve δ Scuti

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 ...

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.

V 1162 Ori: A multiperiodic delta Scuti star with variable period and amplitude [PDF]
Astronomy & Astrophysics, 2001 We present the results of multisite observations of the delta Scuti star V1162 Ori. The observations were done in the period October 1999 - May 2000, when 18 telescopes at 15 observatories were used to collect 253 light extrema during a total of 290 hours of time-series observations.

A Search for Transits among the Delta Scuti Variables in Kepler [PDF]
, 2021 We search for transits around all known pulsating δ Sct variables (6500 K < Teff < 10,000 K) in the long-cadence Kepler data after subtracting the pulsation signal through an automated routine.

The Effects of Metallicity on Convective Overshoot Behavior in Models of δ Scuti Variable Stars
The Astrophysical Journal, 2022 Abstract δ Scuti variables are stars which exhibit periodic changes in their luminosity through radial and nonradial pulsations. Internally, these stars have relatively small convective cores, and convective overshoot can significantly affect the size.

Amplitude Variability of Delta Scuti Stars: 4 CVn [PDF]
International Astronomical Union Colloquium, 2000 AbstractThe amplitude variability of δ Scuti stars is demonstrated by the behavior of the evolved δ Scuti star 4 CVn. The data on 4 CVn covering over 30 yr shows the amplitudes of almost all modes to be extremely variable with a time scales of ten years or longer.

Deriving the structure of pre-supernovae and delta Scuti stars using nonradial oscillations [PDF]
, 1998 This is the final report of a three-year Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The objective is to learn more about the internal structure of two classes of variable stars, by using the ...
