Variable Star Atlas - High Amplitude 𝛿 Scuti Variables
𝛿 Scuti variables are A-F type stars that pulsate both radially and non-radially at very short periods. While their light curves may look similar to RR Lyrae stars, 𝛿 Scuti variables typically have shorter periods (~0.03 - 0.2 days). The abundance of different pulsations in these stars cause their light curves to appear blurry/fuzzy. As the name suggests, High Amplitude 𝛿 Scuti or HADS variables are a separate class of 𝛿 Scuti (DSCT) stars that have higher amplitudes than typical DSCT. Their light curves are often more asymmetric than normal DSCT variables with a steeper ascending branch.
