Similar to Figure 2, except with initial angular momentum budget dominated by the planet orbit. To explore this L ≫ S⋆ regime, this example uses a 900 M⊕ hot Jupiter as well as a slowly rotating star (P⋆ = 30 days; we also use a stellar tidal quality factor Q⋆ = 105). When orbital angular momentum dominates the stellar spin, obliquity tides damp the system into spin–orbit alignment ﹩{before}﹩ Roche-lobe overflow (according to our weak friction, equilibrium tide approach).
