Planetary shadow. Left: distortion of the stellar absorption lines as seen for our observations with HARPS taken on the transit night. The vertical solid lines denote ±v sin i_⋆, and the vertical dashed line is at v = 0 km s⁻¹. The horizontal dashed lines mark the points of second and third contact, which is when the planet is found completely within the stellar disk, and the solid lines denote the first and fourth contact points, where the planetary and stellar disk start to overlap. Middle: best-fitting model of the distortion. Right: residuals from subtracting the best-fitting model from the data. The horizontal bar on top shows the strength of the signal.
