Their fundamental stellar and circumstellar parameters and statistical properties were derived with heterogeneous approaches before Gaia. Our main goal is to contribute to the study of HAeBes from the largest sample of such sources to date, for which stellar and circumstellar properties have been determined homogeneously from the analysis of the spectral energy distributions (SEDs) and Gaia EDR3 parallaxes and photometry. Multiwavelength photometry was compiled for 209 bona fide HAeBes for which Gaia EDR3 distances were estimated. Using the Virtual Observatory SED Analyser (VOSA), photospheric models were fit to the optical SEDs to derive stellar parameters, and the excesses at infrared (IR) and longer wavelengths were characterized to derive several circumstellar properties. A statistical analysis was carried out to show the potential use of such a large dataset. The stellar temperature, luminosity, radius, mass, and age were derived for each star based on optical photometry. In addition, their IR SEDs were classified according to two different schemes, and their mass accretion rates, disk masses, and the sizes of the inner dust holes were also estimated uniformly. The initial mass function fits the stellar mass distribution of the sample within 2<M_star_/M_{sun}_<12. In this aspect, the sample is therefore representative of the HAeBe regime and can be used for statistical purposes when it is taken into account that the boundaries are not well probed. Our statistical study does not reveal any connection between the SED shape from the Meeus et al., 2001A&A...365..476M classification and the presence of transitional disks, which are identified here based on the SEDs that show an IR excess starting at the K band or longer wavelengths. In contrast, only ~28% of the HAeBes have transitional disks, and the related dust disk holes are more frequent in HBes than in HAes (~34% vs 15%). The relatively small inner disk holes and old stellar ages estimated for most transitional HAes indicate that photoevaporation cannot be the main mechanism driving disk dissipation in these sources. In contrast, the inner disk holes and ages of most transitional HBes are consistent with the photoevaporation scenario, although these results alone do not unambiguously discard other disk dissipation mechanisms. The complete dataset is available online through a Virtual Observatory- compliant archive, representing the most recent reference for statistical studies on the HAeBe regime. VOSA is a complementary tool for the future characterization of newly identified HAeBes.2021A&A...650A.182Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/650/A182CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/350 : Gaia EDR3 (Gaia Collaboration, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/650/A182https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/650/A182http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/650/A182https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/650/A182https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/650/A182http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/650/A182GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/650/A182/tableb1 (Stellar parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/650/A182/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/650/A182/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/650/A182/tableb1?GETtext/xml+votable180.050000true1.76083365.6438890.0055555555555555566/852 862 1113-1114 1545 1591 3004 3038 3057 3071 14031 14040 14257 14311 14344 14346 14372 14440 14685 14687 14692 14694 14696 15368 15370 15409 15432 15478 15683-15684 15701 15759 15798 15840 15851 16131 17421 18741 20761 20831 20934 21255 21274 21337 21396 21402 21418 21421 21430 21436 21438-21439 21456-21458 21480 21541 21643 21648 22020 22047 22080 22235 22828 22854-22856 22860-22861 22863 22873 22882 22886 22892 22895 22905 22981 23003 23637 23641 23644 23646 23717 23727 23736 23767 23795 23798 23850 23970 24139 24156 24277 24279 24281 24425 24449 28762 28908 28918 28921 29207 29253 29358 29452 29463 29478 30188 30242-30243 30251 30258 30363 30406 30462 30632 31259 32065 33111 34926 36651 36956 37169 37186 37244 37334 37362 37366 37676 37714 37851 37871 37883 37886 37890 37905 37916 37932 37934 37978 38002 38032 39179 39228 39259-39260 39365 39883 39908 39926 39929 41472 41662 41669 41698 41734 41746 41812 42171 42217 42360 42382 42392 42429 42437 42455 42492 42496 42595 42611 42644 42931 42972 43014 43035 43052 43444 44049 44317 44356 44362 47828 48933https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/650/A182?format=asciidefaultJ/A+A/650/A182/tableb1Stellar parametersSimbadNameSimbad column added by the CDSmeta.idcharNotes[1] Note (2)meta.notecharrecnoRecord number assigned by the VizieR team.
