The jets of microquasars with high-mass stellar companions are exposed to the dense matter field of the stellar wind. We present estimates of the gamma-ray emission expected from the jet-wind hadronic interaction and we discuss the detectability of the phenomenon at high energies. The proposed mechanism could explain some of the unidentified gamma-ray sources detected by EGRET instrument on the galactic plane.

- A hadronic origin for ultra-high-frequency-peaked BL Lac objects (2014, background): “…2012) Proton-proton interactions (important in denser environments, such as supernovae remnants or micro-quasars, see e.g. Ackermann et al. 2013b; Romero et al. 2003, respectively) are commonly neglected in blazar hadronic models, because the particle density in the emitting region is considered…”
- 3.9 day orbital modulation in the TeV gamma-ray flux and spectrum from the X-ray binary LS 5039 (2006, background): “The nature of the parent particles responsible for VHE γ-ray emission is under theoretical discussion, with both accelerated electron (Aharonian & Atoyan 1998, Paredes et al. 2006) and hadron (Distefano et al. 2002, Romero et al. 2003) scenarios proposed.”
- Be/X-ray binaries (2011, background): “…emission arises from the decay of neutral pions created in the inelastic collisions between relativistic protons in the jet and either the ions in the stellar wind of the massive companion star (Romero et al. 2003) or nearby high-density regions (i.e. molecular clouds) (Bosch-Ramón et al. 2005).”
- Gamma-ray binaries and related systems (2013, background): “Jet or corona emission can thus be expected to extend to HE gamma rays (Romero et al. 2003; Dermer & Böttcher 2006; Bosch-Ramon et al. 2006).”
