It is important to understand the properties of heavy vector mesons inside a thermal medium. One of the reasons is that the fraction of such particles detected after a heavy ion collision can provide information about the formation of a plasma state. An interesting framework for estimating the degree of dissociation of heavy mesons in a plasma is the holgraphic approach. We will discuss some recent results showing that a consistent picture for the thermal behavior of charmonium and bottomonium states in a thermal medium emerges from holographic bottom up models. A crucial ingredient in this approach is the appropriate description of decay constants, since they are related to the heigths of the quasiparticle peaks of the finite temperature spectral function. Considering a medium with finite temperature and density, the thermal spectra of $ c \bar c$ and $ b \bar b \, $ S wave states are obtained. A very recent result for a medium with magnetic $e B$ field is also considered.
