Asteroseismology is a powerful method for determining fundamental propertiesof stars. We report the first application to a metal-poor object, namely thesubgiant star nu Ind. We measured precise velocities from two sites, allowingus to detect oscillations and infer a large frequency separation of Delta_nu =24.25 +/- 0.25 microHz. Combining this value with the location of the star inthe H-R diagram and comparing with standard evolutionary models, we were ableto place constraints on the stellar parameters. In particular, our resultsindicate that nu Ind has a low mass (0.85 +/- 0.04 M_sun) and is at least 9 Gyrold.Comment: accpted for publication in Ap
