As many as 10\% of OB-type stars have global magnetic fields, which is surprising given their internal structure is radiative near the surface.

TOI-640 b is one of only three known hot Jupiters to have a highly inflated radius (R$_{\rm P}$ > 1. 7R$_{\rm J}$, possibly a result of its host star's evolution) and resides on an orbit with a period longer than 5 days.

We confirm the planetary nature of the companion via a combination of radial velocities, which limit the mass to $< 4. 1\,\mathrm{M_J}$ $(3\sigma)$, and a clear Doppler tomography signal, which indicates a retrograde projected spin-orbit misalignment of $\lambda = -179. 7^{+3. 7}_{-3. 8}$ degrees.
