SX Phoenicis variable

These stars exhibit a short period pulsation behavior that varies on time scales of 0.03–0.08 days (0.7–1.9 hours).

[2] Compared to the Sun, these stars have a lower metallicity, which means they have a reduced abundance of elements other than hydrogen and helium.

They also have relatively high space velocity and low luminosities for stars of their stellar classification.

[5] SX Phoenicis variables are found primarily in globular clusters and galactic halos.
