Measuring the composition of exocomets

The Beta Pictoris system is a young planetary system embedded in a debris disk that is continually replenished by the collision and evaporation of planetesimals and exocomets. As a result of the edge-on inclination of the debris disk, the gas component of the disk and transiting exocomets can be observed in great detail using absorption spectroscopy. I am currently working on measuring the composition of the exocomets so that I can trace the condensation and evaporation processes present in the late stages of planetary formation to get an insight into the origins of the exocomets of the Beta Pictoris system.
