Informal Discussion
Talk — Impact of 3D NTLE on C/O ratio in stellar atmospheres
Guillaume Guiglion (MPIA Heidelberg)
View Abstract
Abstract
In this talk, I will discuss on the effects of departures from LTE and 1D model atmospheres in
the derivation of C/O ratios in solar-like stars. I will show that using standard 1D LTE approximation
largely underestimates C/O. I will discuss on the impact of such measurements in the context of
planet formation.
