High-energy (ν > ν₀ = 3eB_⋆/4πmc) synchrotron light curves for all runs, as a function of the orbital phase, Φ. Fluxes are integrated over the full polar angle range. Fluxes are normalized by the reference flux computed for the isolated pulsar magnetosphere (black solid line). Different colours stand for different binary separations. Orange dashed and dotted lines stand for different companion sizes. The pulsar-companion direction is given by the black dashed line. Two intense and broad peaks (corresponding to a hollow cone of light in 3D) are induced by the pulsar-companion interaction, which properties depend on the companion distance and size. The angle between peaks is referred to as ΔΦ and the light cone tilt with respect to the pulsar-companion direction is designated by δ_offset.
