About the target
A Delta Scuti variable (sometimes termed dwarf cepheid) is a variable star (opens in a new tab) which exhibits variations in its luminosity (opens in a new tab) due to both radial and non-radial pulsations of the star’s surface. Typical brightness fluctuations are from 0.003 to 0.9 magnitudes (opens in a new tab) in V (opens in a new tab) over a period of a few hours, although the amplitude (opens in a new tab) and period (opens in a new tab) of the fluctuations can vary greatly. The stars are usually A0 to F5 type (opens in a new tab) giant (opens in a new tab) or main sequence (opens in a new tab) stars. The high-amplitude Delta Scuti variables are also called AI Velorum stars. They are the second most abundant variable source in the Milky Way after white dwarfs.
