Abstract
The Rotational Shearing Interforometer has been proposed for direct detection of extra-solar planets. This interferometer cancels the star radiation using destructive interference. However, the resulting signal is too small (few photons/s for each m2). We propose a novel method to enhance the signal magnitude by means of the star–planet interference when the star radiation is not cancelled. We use interferograms computationally simulated to confirm the viability of the technique.
Highlights
In the last twenty years, the interest in exoplanet detection has been increased
We proposed an improvement to the capacity of the RSI for extra-solar planets detection
This technique consists of the non-total cancellation of the star radiation in order to improve the signal magnitude
Summary
In the last twenty years, the interest in exoplanet detection has been increased. More than 4000 planets have been discovered [1], The main interest of the scientific community are the earthlike planets [2]. When the delay between the detection[15,16,17,18] This interferometer interferes the wavefronts with a rotated and interferometer arms is λ/2, the star radiation is canceled, with only the planet radiation delayed version of them. This interferometer may cancel the star radiation in a remaining [12,13,14]. Shearing Interferometer (RSI) for planet positive results rotating wavefront.interferes. When a solitary star is aligned on the optical axis of the interferometer, its wavefront is rotational-symmetrically and the RSI does not produce a fringe pattern. Θ P and φ P are the angles between the planet
