The science of extrasolar planets is one of the most rapidly changing areas of astrophysics and planetary science. Ground-based surveys and dedicated space missions combined have resulted in ~1800 planets detected already, with more than ~3000 awaiting confirmation.
A key challenge, therefore, is now characterization:
what are these planets actually like and why are they as they are?
To answer these questions, a broad range of skills and expertise is required. Hence, we solicit papers related to extrasolar planets, ranging in topics from Solar System science to statistical astrophysics, from ground-based observations to spacecraft measurements, and from atmospheric/interior/orbital modelling to
instrument building.
