Radiative-transfer (RT) is a fundamental part of modelling exoplanet atmospheres with
general circulation models (GCMs). An accurate RT scheme is required for estimates of the …

With JWST slated to gain high-fidelity time-dependent data on brown dwarf atmospheres, it
is highly anticipated to do the same for directly imaged, sub-Jupiter exoplanets. With this …

Context. Over large timescales, a terrestrial planet may be driven towards spin-orbit
synchronous rotation by tidal forces. In this particular configuration, the planet exhibits …

One-dimensional (vertical) models of planetary atmospheres typically balance the net solar
and internal energy fluxes against the net thermal radiative and convective heat fluxes to …

This thesis is an anthology of three theoretical problems in astrophysics with applications to
planetary atmospheres, their immediate external environment, and their birthplaces. The first …
