PRODIMO model for the quiescent state of EX Lupi. The top plots show the assumed gas and dust column densities (left) and scale heights (right). The second row shows the corresponding gas densities (left) and gas-to-dust mass ratio after settling (right). The third row shows the UV field strength χ (left), and the X-ray ionisation rate ζ_X in comparison to the cosmic-ray ionisation rate (right). The bottom row shows the resulting dust-temperature (left) and gas-temperature (right) structures. Additional contour lines show selected values for the vertical optical extinction A_V and the radial optical extinction A_V,rad as indicated.
