The orbit is not yet circularized (e=0.47) and very strong tides are expected. This makes of AK Sco, the ideal laboratory to study the effect of gravitational tides in the stellar magnetic field building up during pre-main sequence evolution. Evidence of this effect is reported in this contribution.engbook parthttp://proceedings.aip.org/resource/2/apcpcs/1094/1/313_1?isAuthorized=nohttp://www.aip.org/open access52Stars: pre-main sequenceStars: magnetic fieldsBinaries: spectroscopicAstronomía (Matemáticas)21 Astronomía y Astrofísica
