  Recent discoveries of a super-virial hot phase of the Milky Way
circumgalactic medium (CGM) has launched new questions regarding the
multi-phase structure of the CGM around the Galaxy. We use 1.05 Ms of archival
Chandra/HETG observations to characterize highly ionized metal absorption at
z=0 along the line of sight of the quasar NGC 3783. We detect two distinct
temperature phases with T$_1 = 5.83^{+0.15}_{-0.07}$ K, warm-hot virial
temperature, and T$_2=6.61^{+0.12}_{-0.06}$ K, hot super-virial temperature.
The super-virial hot phase coexisting with the warm-hot virial phase has been
detected in absorption along only two other sightlines and in one stacking
analysis. There is scatter in temperature of the hot as well as warm-hot gas.
Similar to previous observations, we detect super-solar abundance ratios of
metals in the hot phase, with a Ne/O ratio 2$\sigma$ above solar mixtures.
These new detections continue the mystery of the mechanism behind the
super-virial hot phase, but provide evidence that this is a true property of
the CGM rather than an isolated observation. The super-virial CGM could hold
the key to understanding the physical and chemical history of the Milky Way.
