J. R. North,John Davis,Jane Robertson,Timothy R. Bedding,H. Bruntt,Michael Ireland,A. P. Jacob,Sylvestre Lacour,John O'Byrne,S. M. Owens,D. Stello,William J. Tango,Peter G. Tuthill +12 more
TL;DR: In this article, the angular diameter of the F9 V star beta Virginis was measured using the Sydney University Stellar Interferometer (SUSI) and the authors derived a radius of 1.703 +/- 0.022 R_sun (1.3%).

TL;DR: In this paper, the authors present analyses of solar-like oscillations based on Q6 and Q8 data, identifying angular degree l = 0, 1, and 2 modes with frequencies of 1000-2700 μHz, a large frequency separation of 83.9 ± 0.4 μHz and maximum oscillation amplitude at frequency νmax = 1829 ± 54 μHz.
