The Formation of Planets:
The Critical First Growth Phase

Project A1

OUTLOOK

In this project we aim at answering the following questions:

• Can we estimate the degree of crystallinity from IR spectra and hence the activation energy or do we need additional methods of analysis?
• Is the crystallisation process depending on shape and porosity (i.e. volume filling factor) of the sample?

Further open questions which are also related to other projects

(A2, B2, B3, D2):

• Do the dust particles have a higher porosity than assumed?
• Could a higher porosity influence the sticking conditions of two colliding particles?
• Could it influence the formation of dust aggregates?
