  The static properties, i.e., existence and stability, as well as the
quench-induced dynamics of vortex-bright type excitations in two-dimensional
harmonically confined spin-1 Bose-Einstein condensates are investigated.
Linearly stable vortex-bright-vortex and bright-vortex-bright solutions arise
in both antiferromagnetic and ferromagnetic spinor gases upon quadratic Zeeman
energy shift variations. Their deformations across the relevant transitions are
exposed and discussed in detail evincing also that emergent instabilities can
lead to pattern formation. Spatial elongations, precessional motion and
spiraling of the nonlinear excitations when exposed to finite temperatures and
upon crossing the distinct phase boundaries, via quenching of the quadratic
Zeeman coefficient, are unveiled. Spin-mixing processes triggered by the quench
lead, among others, to changes in the waveform of the ensuing configurations.
Our findings reveal an interplay between pattern formation and spin-mixing
processes being accessible in contemporary cold atom experiments.
