A new approach to the detection of exoplanets

Sahil Agarwal, Fabio Del Sordo, and John Wettlaufer

The detection of Earth-like exoplanets is challenging because several sources of noise hinder from uncovering the imprint of a low-mass planet in observations.

We have implemented a method, called MultiFractal Temporally Weighted Detrended Fluctuation Analysis, to detect planets orbiting a distant star. This makes no use of any fitting procedure to filter out the noise, but instead characterizes it by looking at the fluctuations of the data at different wavelengths. In particular, this approach allows to measure the time scales over which stellar noise operates, thus opening a new door to interpret the data that will come from the next generation of spectrographs.
