A New Method for Unveiling Box/Peanut Bulges in Face-On Galaxies
We measured the stellar kinematics of three face-on galaxies with the aim of searching for box/peanut-shaped (B/P) bulges. These observations test and confirm that face-on B/P bulges can be recognized by two minima in the radial profile of the fourth Gauss-Hermite moment h_4 of the line-of-sight velocity distribution measured along the bar major
