Query: Paramagnetic alignment of thermally rotating dust   Paramagnetic alignment of thermally rotating oblate dust grains is studied
analytically for finite ratios of grain to gas temperatures. For such ratios,
the alignment of angular momentum J in respect to the grain axis of maximal
inertia is only partial. We treat the alignment of J using perturbative methods
and disentangle the problem of J alignment in grain body axes from that of J
alignment in respect to magnetic field. This enables us to find the alignment
of grain axes to magnetic field and thus relate our theory to polarimetric
observations.Our present results are applicable to the alignment of both
paramagnetic and superparamagnetic grains.
