| Abstract: |
From time-series photometry of BQ Ind we derive a primary f1= 12.1951 c/d and a secondary frequency f2= 15.7686 c/d. 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 ~ 1.40 Msun. |
