Electronic Journal of Theoretical Physics Discrete Cosmological Self-Similarity and Delta Scuti Variable Stars [PDF]
, 2008 : Within the context of a fractal paradigm that emphasizes nature’s well-stratified hierarchical organization, the δ Scuti class of variable stars is investigated for evidence of discrete cosmological self-similarity.

Multisite campaign on the open cluster M67 - III. delta Scuti pulsations in the blue stragglers [PDF]
, 2007 International audienceWe have made an asteroseismic analysis of the variable blue stragglers in the open cluster M67. The data set consists of photometric time-series from eight sites using nine 0.6-2.1 m telescopes with a time-baseline of 43 d.

Seismic Constraints on the Spin Evolution of Slowly Rotating Young Intermediate-mass Stars
The Astrophysical Journalδ Scuti stars are hot, rapid rotators and a poorly understood class of pulsators. Asteroseismology provides the only means with which to probe their interior dynamics.

Amplitude Modulation of Pulsation Modes in Delta Scuti Stars [electronic resource] / [PDF]
This outstanding thesis by Dominic Bowman provides a thorough investigation of long-standing questions as to whether amplitude modulation is astrophysical, whether it offers insights into pulsating stars, and whether simple beating of modes with stable ...

Deformation and Differential Rotation in Slowly Rotating Young Intermediate-mass Stars
The Astrophysical JournalAsteroseismology, the study of stellar vibrations, is a method that can probe the structure deformation and internal rotation of stars. Salient among the seismic inferences of rotation from TESS observations are TIC 408165734, whose equatorial rotation ...

KIC 10855535: An Elegant δ Scuti Pulsator with Amplitude and Phase Modulation
The Astrophysical JournalWe investigated the pulsating behavior of KIC 10855535 using Kepler 4 yr long-cadence data. Two independent frequencies were detected: a pulsation frequency F0 = 17.733260(5) day ^−1 and a low frequency f _8 = 0.412643(8) day ^−1 .

Comparing the asteroseismic properties of pulsating extremely low-mass pre-white dwarf stars and delta Scuti stars [PDF]
, 2017 We present the first results of a detailed comparison between the pulsation properties of pulsating Extremely Low-Mass pre-white dwarf stars (the pre-ELMV variable stars) and δ Scuti stars.
