  We study confinement-deconfinement phase transition for heavy quarks in a
bottom-up holographic QCD model. We consider a black hole background in an
Einstein-Maxwell-scalar system and add probe open strings to the background.
Combining the various configurations of the open strings and the phase
structure of the black hole background itself, we obtain the
confinement-deconfinement phase diagram for heavy quarks in the holographic QCD
model.
