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 کاملA submillimeter exponential disk in M 51 : evidence for an extended cold dust disk
A 850 µm map of the interacting spiral galaxy M 51 shows well-defined spiral arms, closely resembling the structures seen in CO and HI emission. However, most of the 850 µm emission originates in an underlying exponential disk, a component that has not been observed before in a face-on galaxy at these wavelengths. The scale-length of this disk is 5.45 kpc, which is somewhat larger than the scal...
متن کاملThe Hd 163296 Circumstellar Disk in Scattered Light: Evidence of Time-variable Self-shadowing
We present the first multi-color view of the scattered light disk of the Herbig Ae star HD 163296, based on coronagraphic observations from the Hubble Space Telescope Advanced Camera for Surveys (ACS). Radial profile fits of the surface brightness along the disk’s semi-major axis indicates that the disk is not continuously flared, and extends to ∼540 AU. The disk’s color (V-I)=1.1 at a radial d...
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...
