Context. GX 301-2 is a high-mass X-ray binary (HMXB) with strong stellar outflows. The evolution of these binaries can be closely related with the interstellar environment due to strong wind interactions.
Aims. We try to constrain the energy injected in the interstellar medium by GX 301-2 through stellar wind using HAWK-I and Herschel data.
Methods. We analysed HAWK-I images in four different filters (Brγ, H2, J, and Ks) and tried to retrieve signatures of the impact of GX 301-2 on its environment. We used Herschel data to outline the interstellar medium and the Gala DR3 catalogue to infer the proper motion of GX 301-2. Finally, we estimated the energy injected in the interstellar medium since the first supernova event of the HMXB.
Results. Using both HAWK-I and Herschel images, we deduce an approximation of the total mass injected from GX 301-2 in the interstellar medium of Minj = 3.05-0.03+0.05 × 10-2 M⊙.
