cds-question@unistra.frmultiple-starsexoplanetsorbitseffective-temperaturestellar-massesmetallicitystellar-radiiPrevious studies showed evidence of a dearth of close-in exoplanets around fast rotators, which can be explained by the combined action of intense tidal and magnetic interactions between planet and their host star. Detecting more exoplanets experiencing such interactions, with orbits evolving on short timescales, is therefore crucial to improve our understanding of the underlying physical mechanisms. For this purpose, we perform a new search for close-in non-transiting substellar companions in the Kepler data, focusing on orbital periods below 2.3 days. We focus on main-sequence solar-type stars and subgiant stars for which a surface rotation period was measured. For each star, we look for an excess in the power spectral density of the light curve, that could correspond to the signature of a close-in non-transiting companion. We compare our candidates with existing catalogues to eliminate potential contaminants in our sample, and we visually inspect the phase-folded light curve and its wavelet decomposition. We identify 88 stars, exhibiting a signature consistent with the presence of a close non-transiting substellar companion. We show that the objects in our sample are located mostly within the dearth zone, emphasising the importance of performing follow-up of such systems in order to gather observational evidence of star-planet interactions.2025A&A...699A.226Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/699/A226CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/244/21 : Surface rotation + activity of Kepler stars.
