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…
Effect of stellar wind on the efficiency of plasma radio emission from exoplanet HD189733b
V. V. Zaitsev, V. E. Shaposhnikov, M. L. Khodachenko +1
On the example of the exoplanet HD 189733 an influence of stellar activity on the efficiency of the plasma mechanism of radio emission generation of the exoplanet and the propertie…
On the origin of the non-detection of metastable HeI in the upper atmosphere of the hot Jupiter WASP-80b
L. Fossati, I. Pillitteri, I. F. Shaikhislamov +5
We aim to narrow down the origin of the non-detection of the metastable HeI triplet at about 10830 A obtained for the hot Jupiter WASP-80b. We measure the X-ray flux of WASP-80 fro…
Global 3D simulation of the upper atmosphere of HD189733b and absorption in metastable HeI and Lyα lines
M. S. Rumenskikh, I. F. Shaikhislamov, M. L. Khodachenko +4
A 3D fully self-consistent multi-fluid hydrodynamic aeronomy model is applied to simulate the hydrogen-helium expanding upper atmosphere of the hot Jupiter HD189733b, and related a…
The GAPS Programme at TNG. XXXII. The revealing non-detection of metastable HeI in the atmosphere of the hot Jupiter WASP-80b
L. Fossati, G. Guilluy, I. F. Shaikhislamov +38
The hot Jupiter WASP-80b has been identified as a possible excellent target for detecting and measuring HeI absorption in the upper atmosphere. We observed 4 primary transits of WA…
The impact of intrinsic magnetic field on the absorption signatures of elements probing the upper atmosphere of HD209458b
M. L. Khodachenko, I. F. Shaikhislamov, H. Lammer +4
The signs of an expanding atmosphere of HD209458b have been observed with far-ultraviolet transmission spectroscopy and in the measurements of transit absorption by metastable HeI.…
Global 3D hydrodynamic modeling of absorption in Lyα and He 10830 A lines at transits of GJ3470b
I. F. Shaikhislamov, M. L. Khodachenko, H. Lammer +3
Warm Neptune GJ3470b has been recently observed in 23S-23P transition of metastable helium, yielding absorption of about 1% in Doppler velocity range of [-40; 10] km/s. Along with…
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…
Three-dimensional modelling of absorption by various species for hot Jupiter HD 209458b
I F Shaikhislamov, M L Khodachenko, H Lammer +3
The absorption of stellar radiation observed by the HD209458b in resonant lines of OI and CII has not yet been satisfactorily modeled. In our previous 2D simulations we have shown…
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…
3D Aeronomy Modeling of Close-in Exoplanets
I. F. Shaikhislamov, M. L. Khodachenko, H. Lammer +3
We present a 3D fully selfconsistent multi-fluid hydrodynamic aeronomy model to study the structure of a hydrogen dominated expanding upper atmosphere around the hot Jupiter HD 209…
