title: Catalogue of young stars with resolved protoplanetary disks

description: The catalogue contains data on 207 young stellar objects (YSOs) of classes II and III with resolved protoplanetary discs, which are located in the Ophiuchus, Upper Scorpius, Taurus, Lupus, Chameleon, and Orion star-forming regions. The information is taken from the original articles (see below), the Strasbourg Astronomical Data Center (CDS, https://simbad.u-strasbg.fr/simbad/), and the Gaia eDR3/DR3 catalogues (Gaia Collaboration 2022, VizieR On-line Data Catalogue I/355). The objects are arranged by star-forming regions. Within each region, entries are sorted alphabetically.

Columns 1 and 2 indicate the name of the star, which is given in the original articles, and the associated star-forming, respectively. Column 3 shows the class of the central star: a classical T Tauri star (CTT, stellar masses range from 0.5 M⊙ to ~ 2 M⊙), a red dwarf (masses from 0.1 M⊙ to 0.5 M⊙), Herbig Ae/Be stars (HAe, masses from 2 M⊙ to ~ 8 M⊙), and YSO – the objects appearing to be younger than CTT or HAe, in which significant envelope emission is observed in the submillimeter range. Column 4 indicates the name of the object according to the 2MASS catalogue. Column 5 shows the spectral class of the star. Columns 6, 7, and 8 show the effective temperature of the star Teff (in Kelvins) and its maximum and minimum errors. Columns 9, 10, and 11 give the luminosity of the star L (in L☉) and its errors. Columns 12, 13, and 14 show the mass of the star Mdyn (in M⊙), determined from the Keplerian rotation of their discs and corresponding errors. Column 15 indicates the stellar mass MGR, obtained by linear interpolation between the evolutionary tracks for pre-main sequence stars (PMS) with M = (0.1-1.40) M⊙ from Baraffe et al. (2015, A&A, 577, A42) and for stars with M = (1.5-5.0) M⊙ from Dotter et al. (2008, ApJSS, 178, 89). Column 16 gives the corresponding error, derived as the mean square of the maximum errors of the luminosity and effective temperature. Columns 17 and 18 contain data on the dust mass Mdust in the protoplanetary disc, measured in the masses of the Earth, and its error. Columns 19 and 20 show the logarithm of the accretion rate onto the star, log(dM⁎/dt) (in units of M⊙/yr), and the corresponding error. Columns 21 and 22 show the angle of the disc inclination with respect to the plane of the sky, i, and its error. Columns 23 and 24 show the position angle of the semi-major axis of the disc, PA, and its error. Column 25 shows the maximum diameter of the disc measured in arcseconds for a specific wavelength (shown in parentheses), and column 26 shows the corresponding diameter in astronomical units. Columns 27 and 28 show the diameter of the disc, determined from the CO emission maps, measured in arcseconds and astronomical units, respectively. The values of the diameters expressed in astronomical units are calculated using new data on distances to stars from trigonometric parallaxes in the Gaia eDR3/DR3 catalogues. The distance, r, expressed in parsecs, and the corresponding error are indicated in columns 29 and 30. Column 31 shows the age of the YSO (t, 106 years), found from the evolutionary isochrons of Baraffe et al. (2015, A&A, 577) and Dotter et al. (2008, ApJSS, 178). Column 32 indicates whether the object belongs to a binary or multiple system: the number of symbols ‘*’ indicates the number of stars in the system, and parentheses around the ‘*’ symbol indicate the presence of a disc around the corresponding star. Column 33 contains hyperlinks to records of the corresponding articles in the ADS database. For each link, the column numbers in parentheses indicate that the column data are taken from that article. An empty cell means that there is no data for the corresponding object.
