Overview of time series of relevant solar wind parameters observed by Solar Orbiter at a heliocentric distance ranging between 0.4 and 0.32 AU. From top to bottom: solar wind bulk speed, V_sw, in km/s; heliocentric distance, R, in AU; v − b correlation coefficient computed at 30 min scale using a running window, C_VB; radial component of the magnetic field, B_R, in nT (black) and magnetic field magnitude, B, in nT (blue); number density, n_p, in cm⁻³; proton temperature, T_p, in K; angle the magnetic field forms with the velocity field, Θ_BV, in degree. The boxes identify the intervals investigated in this study corresponding to portions of Alfvénic slow wind (AS1, AS2, AS3) and fast wind (F).
