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…
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…
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.…
