Photoionization feedback in turbulent molecular clouds
  We present a study of the impact of photoionization feedback from young
massive stars on the turbulent statistics of star-forming molecular clouds.
This feedback is expected to alter the density structure of molecular clouds
and affect future star formation. Using the AMUN- Rad code, we first generate a
converged isothermal forced turbulent density structure inside a periodic box.
We then insert an ionizing source in this box and inject photoionization energy
using a two-temperature pseudo-isothermal equation of state. We study the
impact of sources at different locations in the box and of different source
luminosities. We find that photoionization has a minor impact on the 2D and 3D
statistics of turbulence when turbulence continues to be driven in the presence
of a photoionizing source. Photoionization is only able to disrupt the cloud if
the turbulence is allowed to decay. In the former scenario, the presence of an
HII region inside our model cloud does not lead to a significant impact on
observable quantities, independent of the source parameters.
