Spectral energy distribution (wavelength vs. flux density) of the debris disc host star HD 105. Data points are coloured by wavelength regime: green for optical/near-infrared, blue for mid-infrared (including the Spitzer/IRS spectrum), and red for far-infrared (Herschel/PACS). White data points are ancilliary data, including ALMA 1.3mm and ATCA 9mm observations. Grey lines denote a grid of dust models (grain size and distribution) fitted to the data to determine the best-fit dust properties for the system.
Spectral energy distribution
ALMA Band 6 (1.3mm) naturally weighted image of HD 105, a young pre-main sequence star with a bright debris disc. The disc is spatially resolved, with a radius of ~ 80 au.
A Young Solar System Analogue Imaged by ALMA
Plot of distance vs. disc radius for a sample of 97 spatially resolved debris discs. The colour of each data point denotes the photospheric temperature of the host star. The size of each data point denotes the fractional width (dR/R) of the disc, assuming it is a Gaussian annulus. The black line denotes the limit at which a disc could be resolved by the Herschel satellite observatory. The small black dots denote discs with fractional widths of 0.1, 0.3, 0.5, and 1.0, respectively.
Disc radius as a function of stellar distance
Plot of stellar luminosity vs. disc temperature for a sample of 97 spatially resolved debris discs, taken from Marshall et al. (2021a). The dust temperature is plotted as a ratio with the blackbody temperature (i.e. Tdust/Tbb) at the observed location of the dust disc around each star. A general trend can be seen that the disc temperature tends toward the blackbody temperature for more luminous stars. This indicates that the dust grains responsible for the observed emission are larger around more luminous stars, as expected from dust grain removal through radiation pressure.
Dust temperature vs. stellar luminosity
Plot of stellar luminosity vs. disc radius for a sample of 97 spatially resolved debris discs, taken from Marshall et al. (2021a). The vertical error bars denote the width of the debris disc. Light grey lines denote samples randomly drawn from the posterior probability distribution of a power law fit to the distribution. An increasing trend between disc radius and stellar luminosity is observed, suggesting that larger discs are (generally) found around more luminous stars. The slope of this trend is what would be expected if the CO ice line in primordial protoplanetary discs were responsible for setting the location for planetesimal formation around the host stars.
