Global 3D hydrodynamic modeling of in-transit Lyα absorption of GJ436b

M. L. Khodachenko, I. F. Shaikhislamov, H. Lammer +4

Using a global 3D, fully self-consistent, multi-fluid hydrodynamic model, we simulate the escaping upper atmosphere of the warm Neptune GJ436b, driven by the stellar XUV radiation…
