The history of the cosmos is encrypted in stars. To decipher the evolution of stars, galaxies and the cosmos, we require a deeper understanding of how exactly stars produce the emitted radiation.
The project has investigated how convection transports energy in stars and how it influences the visible surface layers of stars -- the stellar atmospheres -- by means of time-dependent 3-dimensional radiative-hydrodynamical (3D RHD) simulations with realistic treatment of the radiative energy exchange.
In the coming year, the project's goal is to use the 3D RHD simulations to improve stellar evolution calculations, which is an influential work pioneered by our group. All of our stellar models will be made available to the astronomical community, which will be very useful for diverse fields, such as exoplanets, stellar physics, Galactic archaeology, and cosmology.
