Abstract

From time-series photometry of BQ Ind we derive a primary f₁ = 12.1951 d⁻¹ and a secondary frequency f₂ = 15.7686 d⁻¹ . The period ratio P₂/P₁ = 0.7734 suggests that BQ Ind is a double-mode SX Phoenicis Star. With f₁ the fundamental mode and f₂ the first overtone, this ratio leads to an estimate of the mass M ≃ 1.40M☉.
