Abstract:
Close-in giant extrasolar planets ("Hot Jupiters") are believed to be
strong emitters in the decametric radio range. We present the expected
characteristics of the low-frequency magnetospheric radio emission of
all currently known extrasolar planets, including the maximum emission
frequency and the expected radio flux. We also discuss the escape of
exoplanetary radio emission from the vicinity of its source, which
imposes additional constraints on detectability.
We compare the different predictions obtained with all four existing
analytical models for all currently known exoplanets. We also take
care to use realistic values for all input parameters.
Description:
Expected radio emission from presently known exoplanets. For each of
the currently known exoplanets, we list its estimated magnetic moment,
maximum radio emission frequency, plasma frequency in the ambient
stellar wind, and radio fluxes according to three different models.

Note on table1.dat: All planets which are "potentially tidally locked" are
listed twice: once as (TL), and once as (FR).
All values are rounded, so that 0.0 precisely stands for <0.05.

Note (1): Status as follows:
TL = tidally locked
(TL) = potentially tidally locked and assuming tidal locking
(FR) = potentially tidally locked and assuming no tidal locking
FR = no tidal locking
