WebDebris disks—many with just such clumps and arcs—have now been found around many stars, such as HL Tau, located about 450 light-years from Earth in the constellation Taurus (Figure 21.15). In some stars, the brightness of the rings varies with position; around other stars, there are bright arcs and gaps in the rings. WebWe present infrared polarimetric images that demonstrate that the T Tauri star HL Tau is not seen in direct light at lambda <= 2.2 mu m. The position of the intensity centroid moves monotonically southwest from V (0.555 mu m) through J (1.25 mu m) and H (1.65 mu m) to K (2.2 mu m) wave bands. Furthermore, the mean position of the J, H, and K polarimetric …

Webonly strikingdiﬀerence is that the central density (ρ0) of TWHya is5.7 times largerthan that of HL Tau, whichis understood because the core of TW Hya is only half the size (R1) of HL Tau and about twice as heavy (Ω J).
