Whether BP Piscium ( BP Psc ) is either a pre-main sequence T Tauri star at d \approx 80 pc , or a post-main sequence G giant at d \approx 300 pc is still not clear .
As a first-ascent giant , it is the first to be observed with a molecular and dust disk .
Alternatively , BP Psc would be among the nearest T Tauri stars with a protoplanetary disk ( PPD ) .
We investigate whether the disk geometry resembles typical PPDs , by comparing polarimetric images with radiative transfer models .
Our VLT/SPHERE/ZIMPOL observations allow us to perform Polarimetric Differential Imaging ; Reference Star Differential Imaging ; and Richardson-Lucy deconvolution .
We present the first visible light polarization and intensity images of the disk of BP Psc .
Our deconvolution confirms the disk shape as detected before , mainly showing the southern side of the disk .
In polarized intensity the disk is imaged at larger detail and also shows the northern side , giving it the typical shape of high inclination flared disks .
We explain the observed disk features by retrieving the large-scale geometry with MCMax radiative transfer modeling , which yields a strongly flared model , atypical for disks of T Tauri stars .
