Description

ExPRES (Exoplanetary and Planetary Radio Emission Simulator) reproduces the occurrence of CMI-generated radio emissions from planetary magnetospheres, exoplanets or star-planet interacting systems in time-frequency plane, with special attention given to computation of the radio emission beaming at and near its source. Physical information drawn from such radio observations may include the location and dynamics of the radio sources, the type of current system leading to electron acceleration and their energy and, for exoplanetary systems, the magnetic field strength, the orbital period of the emitting body and the rotation period, tilt and offset of the planetary magnetic field. Most of these parameters can be remotely measured only via radio observations. ExPRES code provides the proper framework of analysis and interpretation for past (Cassini, Voyager, Galileo), current (Juno, ground-based radio telescopes) and future (BepiColombo, Juice) observations of planetary radio emissions, as well as for future detection of radio emissions from exoplanetary systems.

Change Log for version 1.4.0:

  • Configuration:
    • Add the possibility for users to provide magnetic field and density models
    • The option to have sources located on magnetic field lines with the M Shell is now available for all target
    • Distance values units can either be in physical units (km) or in Planetary Radius (it needs to be consistent all through the config file). Physical units (km) are recommanded. Planetary Radius units can still be used, except in the two following cases:
      • If OBSERVER TYPE == Pre-Defined
      • If [BODY][PHASE] == "auto" (for body ≠ central body)
  • Others:
    • Creation of codemeta.json file
  • Documentation:
    • Updated readthedocs documentation, available at: https://expres.readthedocs.io/en/latest/
