Evidence for an Extended Scattered Disk
By telescopic tracking, we have established that the transneptunian object (TNO) 2000 CR105 has a semimajor axis of 220 ± 1 AU and perihelion distance of 44.14 ± 0.02 AU, beyond the domain which has heretofore been associated with the “scattered disk” of Kuiper Belt objects interacting via gravitational encounters with Neptune. We have also firmly established that the TNO 1995 TL8 has a high pe...
متن کاملProduction of the Extended Scattered Disk by Rogue Planets
We show that if the early outer solar system contained one or more additional planets of an Earth mass or larger, these planets are likely to be temporarily emplaced in the Kuiper Belt’s “scattered disk.” While on an orbit of large semimajor axis, such a “rogue planet” may efficiently raise either (1) the perihelia of other scattereddisk objects, emplacing them in the “extended scattered disk,”...
متن کاملUnraveling the Transitional Disk RX J1615.3-3255: Scattered Light Observations Versus Disk Models
We present a two-stage analysis of the transitional disk RX J1615.3-3255 located in the Lupus association (∼1 Myr old). Using 1.6 μm scattered light, polarized intensity images observed with the HiCIAO instrument of the Subaru Telescope, we deduce the position angle and the inclination angle. The disk is found to extend out to 92 ± 12 AU in the scattered light and no clear structure is observed...
متن کاملStructures in the Protoplanetary Disk of Hd142527 Seen in Polarized Scattered Light
We present Hand Ks-band polarized differential images (PDI) of the Herbig Ae/Be star HD142527, revealing its optically thick outer disk and the nearly empty gap. The very small inner working angle (∼0.1′′) and high resolution achievable with an 8m-class telescope, together with a careful polarimetric calibration strategy, allow us to achieve images that surpass the quality of previous scattered...
