Recent progress in the theoretical understanding and design of compact stellarators is described. Hybrid devices, which depart from canonical stellarators by deriving benefits from the bootstrap current which flows at finite beta, comprise a class of

A new class of low aspect ratio toroidal hybrid stellarators is found using more general plasma confinement optimization criterion than quasi-symmetrization. The plasma current profile and shape of the outer magnetic flux surface are used as control

A class of small aspect ratio (A) stellarators is found that does not rely on quasisymmetrization to achieve good confinement. These systems depart from canonical stellarators by allowing a small net plasma current. An optimization procedure with bou
