Notes. The opacity model by Lin & Papaloizou (1985; here referred to as LP85) functionally translates to κ = 5 × 10−4 T2 within our simulation domain (T < 170 K). Only the two models labeled “base” (Cols. 1 and 7) are discussed in the results section; the remaining models (Cols. 2–7) were used to verify our results and are discussed in Appendix A. Dashes imply that a parameter is inherited from the base model (Col. 1 for HD 163296). In our radiative models, the energy equation allows temperature-related quantities (i.e., hp, Tp, κ if defined by LP85) to evolve throughout the simulation. These are otherwise kept fixed in the corresponding locally isothermal runs.
