cds-question@unistra.frwhite-dwarf-starsphotometryvisible-astronomyeffective-temperatureThe presence of infrared (IR) excess flux observed in white dwarfs is related to the existence of debris disks or substellar companions. These systems provide important clues in the study of extrasolar planetary material and binary evolution. However, fully characterising their properties requires as statistically significant, complete sample. This work aims to identify a complete sample of white dwarfs with infrared excess emission within 100pc of the Sun. We built the spectral energy distributions (SEDs) of the white dwarfs using synthetic photometry in 56 optical filters of the Javalambre Physics of the Accelerating Universe Astronomical Survey system, generated from Gaia Data Release 3 low-resolution spectra and complemented with the latest infrared photometry available at the Virtual Observatory (VO). VOSA was used to fit the SEDs with different atmospheric white dwarf models depending on the source spectral type. We visually checked optical and infrared images to identify contaminated photometry. We built a catalogue of 456 infrared excess white dwarfs, of which 292 are robust identifications, and 164 are candidates. 351 (75%) are new identifications. This implies a fraction of infrared excess white dwarfs between 5.9+/-0.3% and 9.2+/-0.4%, higher than previous works, but in agreement with some more recent estimates. Furthermore, for the sample of infrared excess white dwarfs, the fraction of sources with non-hydrogen atmosphere increases with the Gaia GBP-GRP colour, contrary to the general white dwarf population. However, this result should be interpreted with caution. Additionally, a thorough comparison of our catalogue with those of previous studies was performed. The sample of white dwarfs with infrared excess emission within 100pc presented in this work is the largest, most complete and reliable to date. Due to their proximity, they are ideal targets for follow-up studies aimed at characterising circumstellar disks, substellar companions, and the composition of accreted planetary material.2026A&A...707A.268Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/707/A268CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/355 : Gaia DR3 Part 1.
