  Using the Bogoliubov de-Gennes formalism, we investigate the charge and
spin-dependent thermoelectric effects in superconductor graphene junctions.
Results demonstrate that despite normal-superconductor junctions, there is a
temperature-dependent spin thermopower both in the graphene-based
ferromagnetic-superconductor (F-S) and ferromagnetic-Rashba spin-orbit
region-superconductor (F-RSO-S) junctions. It is also shown that in the
presence of Rashba spin-orbit interaction, the charge and spin-dependent
Seebeck coefficients can reach to their maximum up to 3.5$k_B/e$ and
2.5$k_B/e$, respectively. Remarkably, these coefficients have a zero-point
critical value with respect to magnetic exchange field and chemical potential.
This effect disappears when the Rashba coupling is absent. These results
suggest that graphene-based superconductors can be used in spin-caloritronics
devices.
