We present photometric and spectroscopic analysis of the bright detached eclipsing binary BG Ind .
The masses of the components are found to be 1.428 \pm 0.008 and 1.293 \pm 0.008 M _ { \odot } and the radii to be 2.290 \pm 0.017 and 1.680 \pm 0.038 R _ { \odot } for primary and secondary stars , respectively .
Spectra- and isochrone-fitting coupled with colour indices calibration yield [ Fe / H ] = -0.2 \pm 0.1 .
At an age of 2.65 \pm 0.20 Gyr BG Ind is well advanced in the main-sequence evolutionary phase - in fact , its primary is at TAMS or just beyond it .
Together with three similar systems ( BK Peg , BW Aqr and GX Gem ) it offers an interesting opportunity to test the theoretical description of overshooting in the critical mass range 1.2 – 1.5 M _ { \odot } .
