###Characterising Exoplanets: Theory and Data Driven perspectives###

1. Intro

Science Drivers - Planetary System formation and Life

Habitability - theory driven "habitable zone" - must understand composition/geology/atmoph. heat transport & dynamics/ hist & evol of atmos.

####Should be skeptical of data-poor theory driven expectations####

Exoplanet obs. are approachind data volume/quality of pre-space solar system obsns.

### Interface % theory & observn ####

Depends on question - parameter estimaion
-model selection

also whos asking question: Planetry Scietist / stellar astronomers

obsn(masses/raddii/orbits)->theory(bulk comp/dynam hist)->'obs'/ther(planet formation models)

Observations:

transiting planets (spectr-> radius & atmos)
eclipse spec (atmos)

High Res Spec -> atmos

Radial vel -> mass & dynamics

Direct imaged -> astrometric orbits-> mass & dynam
