Sumario:[Context] Colliding wind binaries are massive systems featuring strong, interacting stellar winds which may act as particle accelerators. Therefore, such binaries are good candidates for detection at high energies. However, only the massive binary η Carinae has been firmly associated with a γ-ray signal. A second system, γ Velorum, is positionally coincident with a γ-ray source, but we lack unambiguous identification.
