Mysterious non-detection of HeI (23S) transit absorption of GJ436b
M. S. Rumenskikh, M. L. Khodachenko, I. F. Shaikhislamov +4
Possible reasons for the non-detection of absorption in the metastable HeI(2^3S) line at transit observations of warm Neptune GJ436b, in spite of the well pronounced strong absorpt…
Three-dimensional hydrodynamic simulations of the upper atmosphere of Men c: comparison with Ly transit observations
I. F. Shaikhislamov, L. Fossati, M. L. Khodachenko +5
Aims: We aim at constraining the conditions of the wind and high-energy emission of the host star reproducing the non-detection of Ly planetary absorption. Methods: We model the…
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…
Implication of Kinetic Alfven Waves to Magnetic Field Turbulence Spectra: Earth's Magnetosheath
N. K. Dwivedi, S. Kumar, P. Kovacs +5
In the present paper, we investigate the power-law behaviour of the magnetic field spectra in the Earths magnetosheath region using Cluster spacecraft data under solar minimum cond…
Modelling atmospheric escape and MgII near-ultraviolet absorption of the highly irradiated hot Jupiter WASP-12b
N. K. Dwivedi, M. L. Khodachenko, I. F. Shaikhislamov +8
We present two-dimensional multi-fluid numerical modelling of the upper atmosphere of the hot Jupiter WASP-12b. The model includes hydrogen chemistry, and self-consistently describ…
