Example dust tail morphology of KIC 1255b found by our numerical dynamics and sublimation calculation (black lines). The ◯-symbols shown at several points along the stream are placed at equal intervals of travel time. Their size is proportional to the local grain size. An ×-symbol marks the point where the dust grains are fully sublimated. For comparison, a dust path ignoring sublimation is shown in grey. Several orbits of the dust grain are shown, which results in a rosette-like shape in the corotating frame (see, also, Fig. 1 of Paper I). The dotted line indicates the orbit of the planet. Top: the dust tail and host star from the observer’s point of view at the time of mid-transit. Middle: view looking down onto the planet’s orbital plane. Bottom left: angle between a dust grain and the planet as a function of time. The vertical dashed line indicates the orbital period of the planet P_p. Bottom right: grain size as a function of angle behind the planet Δθ.
