We present high-precision spectropolarimetric observations of this star, obtained with ESPaDOnS at the Canada France Hawaii Telescope (CFHT) in the frame of the BRITE spectropolarimetric survey. A magnetic field is clearly detected in $\\rho$ Pup, with a longitudinal field strength below 1 G. This makes $\\rho$ Pup the second known magnetic $\\delta$ Scuti discovered, after HD 188774, and a possible cool evolved counterpart of the ","authors_text":"C. Neiner, G. A. Wade, J.
