VizieR Online Data Catalog: Stellar parameters for 131 Herbig Ae/Be stars (Arun+, 2019)
Abstract
A sample of 142 stars is taken from Mathew et al. (2018ApJ...857...30M), which is a carefully selected, well-studied sample of HAeBe stars from The et al. (1994 ,J/A+AS/104/315), Manoj et al. (2006, J/ApJ/653/657), and Fairlamb et al. (2015, J/MNRAS/453/976). The coordinates, proper motions, and V magnitudes of the 142 stars are taken from the literature. R.A. and decl. of these stars are converted from J2000 to J2015.5 epoch using their proper motion. A query for a Gaia DR2 match for these stars was then performed around the converted coordinates with a search radius of 10 arcsec via the Mikulski Archive for Space Telescopes (http://archive.stsci.edu/). If a match was not found, then the search radius was increased up to 30 arcsec. This procedure returned 354 Gaia DR2 rows for 142 stars. For 60 stars, only one Gaia DR2 match was returned. For the remaining 82 stars with multiple entries, those which had |G-V| mag>3.5 were removed. For the remaining multiple entries, the Gaia DR2 row with the closest positional match was selected for which |G-V| mag=<2. Thus we got the Gaia DR2 parallax and magnitudes for all stars in the sample. After avoiding 11 sources, where 6 showed no parallax data and 5 had negative parallax, we finalized our sample of HAeBe stars to be 131. These stars are found in the distance range of 0.09-6 kpc, with a range in Gaia G-band magnitude from 4.4 to 14.5 mag.
