Polarimetry of planetary systems

Group shot

Dates: 23-26 September, 2013

Location: Florence, Italy, Villa Il Gioiello (Galileo's house),  via del Pian dei Giullari, 42 - Firenze


Polarimetric techcniques are routinely exploited to study the surface structure of the atmosphere-less bodies of our solar ystem, the atmospheres of Venus, Earth, and of the giant planets. More recently, polarimetry has gained popularity as a potential tool for the study of exo-solar planets. This workshop will be an opportunity to strengthen the community of astronomers interested in polarimetry of the objects of our and other solar systems, and to discuss what are the open questions that can be addressed by polarimetry. This workshop will be also an opportunity to coordinate future projects.

Participants will be invited to give presentations, but high priority will be given to guided discussions. Subjects covered are:

- Observations of asteroids
- Observations of comets
- Observations of centaurs and TNOs
- Observations of the atmospheres of the bodies of our solar system
- Polarimetry of extra-solar planetary systems
- Modelling of the atmospheres of the exo-solar planets
- Auroral/Thermospheric lines
- Observations of bio-signatures
- Modelling of the surface structure of the atmosphere-less bodies of our solar system
- Observations and data reduction techniques
- Current and future instrumentation
- Polarimetry for a larger audience

The workshop will be limited to 40 participants. There will be some financial support from the COST action for some of them. If you want financial support you can request it on the registration page.

The workshop venue has several rooms that will be available to small working groups.
