Wind parameter space sweep. Color coded values of photospheric magnitudes for different values of parameters (Ṁ, Ė). From top to bottom: temperature, velocity, radius, and luminosity ratio Γ. Points marked with up or down triangles (△/▿) correspond to “thin” and nonstationary solutions, respectively. Points marked with filled circles (•) are self-consistent solution candidates. The × symbol denotes no solutions found for the given boundary conditions. The fully colored area marks solutions whose wind base is compatible with possible neutron star radii (7 − 20 km), and white diamonds inside of it (⋄) mark selected solutions plotted in Fig. 1.
