Comparison of temperature and overpressure of runs CygX1_T7, CygX1 and CygX1_T9, the color-coding is the same as in Fig. 12. Top: evolution of the zone-averaged temperature with simulation time. CygX1 and CygX1_T7 differ only slightly at first, but then start to evolve differently after the 5000 s mark. CygX1_T9 shows an overall higher temperature, with a small peak in inner cocoon temperature around t = 6000 s. Bottom: evolution of the ratio of the inner cocoon to beam pressure, as defined Sect. 3.3.1. CygX1 and CygX1_T7 present similar values up to t ∼ 5000 s, while CygX1_T9 presents a stronger overpressure.
