The Archive

318 confirmed Herbig Ae/Be stars in the archive.

The number of parameters -columns- displayed can be selected through the "verbose" option. 

The core of the archive is made by 209 sources, based on "Homogeneous study of Herbig Ae/Be stars from spectral energy distributions and Gaia EDR3" (Guzmán-Díaz et al. 2021, A&A, 650, A182). Associated documentation can be consulted following the previous link. Please refer to this paper if you make use of the archive in your work. In short, the stellar and circumstellar properties listed for each source were derived from SED analysis with VOSA. Gaia EDR3 parallaxes (Lindegren et al. 2020) and photometry (Riello et al. 2020) were used in all cases. The sample was initially selected from Vioque et al. (2018, A&A, 620, A128). Stellar temperatures and errors compiled in that paper constraint the input range of SED models used to derive the final parameters in the archive for most stars, as indicated by the column "deltaT". 93 sources have stellar parameters homogeneously derived from spectroscopy by Wichittanakom et al. (2020, MNRAS, 493, 234; "W2020"). The column "deltaT" for these sources is based on the latter work. Distance-inpependent values for the stellar temperatures and visual extinctions derived in W2020 are also listed in the archive. 

Data columns available for 109 additional sources were added to the archive on July 2022, based on Vioque et al. (2022, ApJ, 930, 39). Following that work, the nomenclature "VOS" is used for these stars. Please refer to the previous paper if you make use of data related to such sources in your work. The optical and near-infrared UBVRIJHK photometry listed in the archive is based on Gaia DR3 synthetic photometry (Gaia Collaboration 2022), APASS (Henden et al. 2015), and 2MASS (Skrutskie  et al. 2006).
