Notes. Row 2: spectral type of host star. Row 3: stellar distance. Row 4: stellar age. Row 5: orbital distance. Row 6: planetary mass. Row 7: planetary radius. Row 8: expected maximum emission frequency (under the hypothesis planetary rotation does not have any influence on the planetary magnetic field). Row 9: maximum expected radio flux density at Earth (under the hypothesis planetary rotation does not have any influence on the planetary magnetic field). Row 10: expected maximum emission frequency (under the hypothesis planetary rotation has a strong influence on the planetary magnetic field). Row 11: maximum expected radio flux density at Earth (under the hypothesis planetary rotation has a strong influence on the planetary magnetic field).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
