Abstract
For the analysis done in this work, we have used a sample of 220 sub-Neptune candidates from the TFAW-survey. Those candidates are the result of the application of EVEREST 2.0 pipeline, the detrending and denoising TFAW algorithm, and TLS to light curves from the K2 mission.
They also passed through a set of vetting processes including visual inspection of the light curves, revision of high-resolution images and FPP< 2% from VESPA algorithm. From this sample, we choose the 38 candidates with more chances of being detected by the TESS mission or groundbased telescopes attending to their TESS magnitudes and transit depths. We apply to them two extra vetting procedures to better pick out between false positives and candidates: analysis of their host stars Gaia eDR3 astrometric parameters and a PSF centroid test. We finally obtain a set of 34 candidates, 24 of which have not been previously published. We present nine new candidates in the Radius gap and eight new multiplanetary systems, one of them with four candidates
