Radial and Vertical Constraints On The Icy Origin Of H2CO In The HD 163296 Protoplanetary Disk
H2CO is a small organic molecule widely detected in protoplanetary disks. As a precursor to grain-surface formation of CH3OH, H2CO is considered an important precursor of O-bearing organic molecules that […]

NLTE Modelling Of Water-rich Exoplanet Atmospheres. Cooling And Heating Rates
The hydrogen and water molecules respond very differently to the collisional-radiative processes taking place in planetary atmospheres. Naturally, the question arises whether H2O-rich atmospheres are more (or less) resilient to […]
