Abstract
Being remnants of majority of main sequence stars, white dwarfs keep important information on evolution of stellar populations and planetary systems. This information can be decoded by accurate modeling and proper characterization of extreme atmospheres of these stars. We will show how modern computational approaches combined with excellent data acquired from large space telescopes such as GAIA or JWST, enable revealing intriguing stellar evolution history and probing interior compositions of extrasolar planetary bodies.
The Hubble Space Telescope detects the spectral signature of the vaporized debris that revealed a combination of rocky-metallic and icy material, the ingredients of planets. The findings help describe the violent nature of evolved planetary systems and the composition of its disintegrating bodies.
