Summary[edit]

Description
English: The disk of WISE J080822.18-644357.3 (red dwarf) according to Murphy, Mamajek & Bell 2018 (https://ui.adsabs.harvard.edu/abs/2018MNRAS.476.3290M/abstract). 2D-illustration with the help of Adobe Elements Photoshop.

The outer disk has a temperature of 240 K and lies at 25 solar radii (0.115 au). No width of the outer disk was provided, so I did choose a relative large radius randomly. Note that ALMA observations (Faherty et al. 2019 https://ui.adsabs.harvard.edu/abs/2019ApJ...872...92F/abstract) suggests a radius smaller than 16 au and an outer temperature of 20 K (not shown here).

The inner disk has a temperature of 1100 K and lies at 1.2 solar radii (0.0056 au). I choose a small radius.

Note that there is likely material in between the two disks, but less than in the two disk components.

Finally the star has a temperature of about 3100 K (shown here in white) and a radius of about 0.3 solar radii.

Note about the scale: 0.01 au is about 2.1 solar radii.
