Image Details
Caption: Figure 2.
On the left is the science raw image of HIP 65426. This pattern (interferogram) is obtained on the detector and is a result of the interference of the light emerging from each of the subapertures of the mask, as shown in Figure 1. On the right is the associated power spectrum of the science image, which is the modulus squared of its Fourier transform. The power spectrum is used to extract the orbital properties of a potential companion in the star system by analyzing the Fourier observables. The observations in the figure are taken at 3.80 μm.
