  HD\,37776 (V901\,Ori, B2\,Vp), also known as Landstreet's Star, is possibly
the most remarkable magnetic chemically peculiar (mCP) star known. Zeeman
Doppler Imaging revealed this young, rapidly rotating star's surface magnetic
field to be not only the strongest ($\sim 30$ kG) of the He-strong class of hot
mCP stars but also by far the most topologically complex. In contrast to the
overwhelming majority of mCP stars, which are well described by tilted dipoles,
Landstreet's Star's non-axisymmetric surface magnetic field is entirely
dominated by high-order spherical harmonics. It is one of the handful of stars
for which rotational period change has been measured, and over the past two
decades of monitoring, the object has demonstrated an unexpected acceleration
in its rotation that so far defies explanation. Recently acquired TESS data
have provided a photometric data set of unprecedented precision. These data
have revealed a highly stable yet multi-featured light curve, making
Landstreet's Star the prototype of hot mCP stars whose light curves are
difficult to reproduce using the standard model of chemical/photometric spots
modulated by solid-body rotation.
