Query: The Influence of Coronal Mass Ejections on the Gas Dynamics of the
  Atmosphere of a "Hot~Jupiter" Exoplanet   The results of three-dimensional numerical simulations of the gas dynamics of
the atmosphere of a "hot Jupiter" exoplanet during the passage of a coronal
mass ejection (CME) from the central star are presented. These computations
assumed the parameters for the stellar wind and the CME to be typical of the
solar values. The characteristic variations of the flow pattern are considered
for quasi-closed and closed (but appreciably distorted by the gravitational
influence of the star) gaseous envelopes of the exoplanet. It is shown that a
typical CME is sufficient to tear off the outer part of an asymmetric envelope
that is located beyond the Roche lobe and carry it away from the exoplanet.
This leads to a substantial increase in the mass-loss rate from the exoplanet
envelope during the passage of CMEs. The mass-loss rate grows by about a factor
of 11 for a closed envelope, and by about a factor of 14 for a quasi-closed
envelope. Possible evolutionary consequences of the loss of part of the
atmosphere during the passage of CMEs are discussed.
