Stellar rotation is a fundamental observable that drives different aspects ofstellar and planetary evolution. In this work, we present an unprecedentedmanifold analysis of 160 B-type stars with light curves collected by the TESSspace mission using three different procedures (Fast Fourier Transform,Lomb-Scargle, and wavelet techniques), accompanied by rigorous visualinspection in the search for rotation periodicities. This effort providesrotational periodicities for 6 new TESS B-type stars and confirmedperiodicities for 22 targets with rotation periods previously listed in theliterature. For other 61 stars, already classified as possible rotationalvariables, we identify noisy, pulsational, binarity, or ambiguous variabilitybehavior rather than rotation signatures. The total sample of 28 potentialrotators shows an overlap of different classes of rotational variables,composed of $\alpha^2$ Canum Venaticorum, rotating ellipsoidal and SX Arietisstars. The combination of the three techniques applied in our analysis offers asolid path to overcome the challenges in the discrimination of rotation fromother variabilities in stellar light curves, such as pulsation, binarity orother effects that have no physical meaning. Finally, the rotationalperiodicities reported in the present study may represent important constraintsfor improving stellar evolution models with rotation, as well as asteroseismicstudies of hot stars.
