Figure 1.
Sensitivity map of J1407 from SAM imaging at the VLT. Left-hand panel: the star is at the centre of the image, the grey-scale and side bar indicate the sensitivity in delta Ks magnitudes for a 3σ point source detection. The contours indicate the associated upper mass limits in units of Jupiter masses (MJup) estimated from the Ks photometry and models from Allard, Homeier & Freytag (2012a). North is up and east to the left. Right-hand panel: azimuthally averaged sensitivity map. The hashed region indicates circular orbital periods of P < 850 d that are ruled out by Mamajek et al. (2012).
