| Zusammenfassung |
| All strongly magnetized planets of the solar system are known to be sources of intense
nonthermal radio emission. For close-in giant exoplanets (“Hot Jupiters”), the interaction of
the planet with the stellar wind is believed to be much stronger than for planets at larger
orbital distances. This should result in radio emission much stronger than that of Jupiter,
which is one of the strongest radio sources of the solar system. From known planetary
characteristics, one can estimate the expected characteristics of the low-frequency
magnetospheric radio emission of all currently known extrasolar planets, the most important
of which are the maximum emission frequency and the total expected radio flux. We present
an update on the expected radio flux from exoplanets and discuss the escape of
exoplanetary radio emission from its source, which imposes additional constraints
on detectability. These results are used to select the best targets for ground-based
observations. |
