| Zusammenfassung |
| We present initial investigations of the chemical composition of hot, Low Mass Low Density planets. Using a recently-developed column model having a straightforward chemistry scheme (incorporating only C, H, O and N species) as a first step which employs gas-phase rate coefficients valid over a wide temperatures range we input planetary properties for GJ1214-b. We then vary the bulk gas from a pure steam (water)-atmosphere to a solar-type (molecular hydrogen and helium dominated) atmosphere and investigate associated compositional changes e.g. in active minor species such as hydrogen- and nitrogen-oxides. |
