  After a brief review on how heavy quark symmetry constraints the helicity
fragmentation probabilities for a heavy quark hadronizes into heavy-light
hadrons, we present a heavy quark fragmentation model to extract the value for
the Falk-Peskin probability $w_{3/2}$ describing the fragmentation of a heavy
quark into a heavy-light meson whose light degrees of freedom have angular
momentum ${3 \over 2}$. We point out that this probability depends on the
longitudinal momentum fraction $z$ of the meson and on its transverse momentum
$p_\bot$ relative to the jet axis. In this model, the light degrees of freedom
prefer to have their angular momentum aligned transverse to, rather than along,
the jet axis. Implications for the production of excited heavy mesons, like
$D^{**}$ and $B^{**}$, are briefly discussed.
