3D RMHD simulations of jet-wind interactions in high-mass X-ray binaries

Abstract: Context. Relativistic jets are ubiquitous in the Universe. In microquasars, especially in high-mass X-ray binaries, the interaction of jets with the strong winds driven by the massive and hot companion star in the vicinity of the compact object is fundamental for understanding the jet dynamics, nonthermal emission, and long-term stability. However, the role of the jet magnetic field in this process is unclear. In particular, it is still debated whether the magnetic field favors jet collimation or triggers more… Show more

“…Indeed, shortterm variability of high-energy emission seems to be a common feature in gamma-ray binaries (e.g., Bosch-Ramon et al 2005;Smith et al 2009;Takahashi et al 2009;Rea & Torres 2011;An et al 2015;Tam et al 2018). Studies of the clumpy-wind presence have also been performed, for instance, in the context of massive-star binaries (Pittard 2007), accreting X-ray sources (e.g., Oskinova et al 2012), and microquasars (e.g., Araudo et al 2009;Owocki et al 2009;López-Miralles et al 2022).…”

“…This plot shows relevant information about the field structure in the jet spine, which was hidden by the mixed plasma in the cocoon in our representation in López-Miralles et al. (2022). Since the magnetic field within the cocoon is low compared with that in the jet, we have applied a linear transparency to the field lines, weighted by the field vector module.…”

“…The RMHD simulations are run with the code lóstrego (López-Miralles et al. 2022), which uses the same basic strategy, although with different schemes: (i) primitive variables are reconstructed using piecewise linear methods: MinMod (Roe 1986), monotonized central (MC) (van Leer 1977) or VanLeer (van Leer 1974), with slope limiters that preserve monotonicity (Suresh & Huynh 1997), (ii) the approximate solvers used to compute the fluxes are Harten-Lax-Van Leer (HLL) (Harten, Lax & van Leer 1983), HLLC (Mignone & Bodo 2006) and HLLD (Mignone, Ugliano & Bodo 2009). In this case, the divergence-free condition of the field is maintained by using the constrained transport technique (Evans & Hawley 1988; Ryu et al.…”
