---|---|---|---|---|---|---|
G2V | 48, 4.50 | 46.9, 15.6 | 2.74 × 104 | 6092 ± 8 | 0.89 | 0.70 |
K2V | 30, 2.88 | 29.3, 9.80 | 4.06 × 104 | 4856 ± 4 | 0.93 | 0.83 |
M0V | 12, 1.07 | 11.72, 3.92 | 6.70 × 104 | 3858 ± 1 | 0.97 | 0.89 |
Notes. The boxes have the same extent and resolution in the X and Y horizontal directions. The temperatures listed are the average disc-center effective temperature calculated from the bolometric intensity (see Appendix A for further details). LX, LZ refer to the horizontal (LX = LY) and vertical extent of the simulation boxes, dx, dz refer to the horizontal (dx = dy) and vertical resolution, gsurf refers to the constant surface gravity, and the subscripts qs, u, p refer to the quiet-star, umbral, and penumbral temperatures respectively, with umbra, penumbral, and quiet star region, as described in Appendix A.
