- Abstract
- The results of absorption modeling in the hydrogen H 6563 Å and helium 10830 Å lines for the hot Jupiter HAT-P-32 b are presented. The modeling was performed using a three-dimensional hydrodynamic code together with the Monte Carlo model of Ly photon transport. A wide range of stellar radiation and atmospheric parameters was considered. It was found that the measured spectrally resolved transit absorption in both lines can be well described by model calculations with the stellar radiation in the XUV range limited to 200 erg/cm/s per 1 AU, the helium content in the planet's atmosphere He/H=2/98 and metallicity [Fe/H] = -1. It is shown that absorption in the helium line occurs uniformly in a large volume of the outflowing atmosphere, and in the hydrogen line — in a layer of 1.5–2.75 planet radii.
