The Warped Circumstellar Disk of Hd100546
We propose that the two armed spiral features seen in visible Hubble Space Telescope images of scattered light in HD100546’s circumstellar disk are caused by the illumination of a warped outer disk. A tilt of 6-15 degrees from the symmetry plane can cause the observed surface brightness variations providing the disk is very twisted (highly warped) at radii greater than 200 AU where the spiral f...
متن کاملThe Warped Debris Disk of Hd100546
We propose that the two armed spiral features seen in visible HST images of scattered light in HD100546’s debris disk are caused by surface gradient variation of a warped optically thin disk. A tilt of 6-10 degrees from the symmetry plane can cause the observed surface brightness variations providing the disk is geometrically thin, optically thin and very twisted (highly warped) at radii greate...
متن کاملA precessing warped accretion disk around the X - ray pulsar
We have performed an analysis and interpretation of the X-ray light curve of the accreting neutron star Her X-1 obtained with the ASM RXTE over the period 1996 February to 2004 September. The averaged X-ray light curves are constructed by means of adding up light curves corresponding to different 35 day cycles. A numerical model is introduced to explain the properties of the averaged light curv...
متن کاملStar Counts and the Warped and Flaring Milky Way Disk
This paper reports the star count predictions of warped and flaring models of the outer Milky Way disk. These have been suggested as possible locations of the lenses responsible for the microlensing events towards the Large Magellanic Cloud (LMC). Three such models are investigated in detail and the theoretical predictions are confronted with Hubble Space Telescope (HST) star count data in 7 lo...
متن کاملDegree Reduction of Disk Wang-Bézier Type Generalized Ball Curves
A disk Wang-Bézier type generalized Ball curve is a Wang-Bézier type generalized Ball curve whose control points are disks in a plane. It can be viewed as a parametric curve with error tolerances. In this paper, we discuss the problem of degree reduction of disk Wang-Bézier type generalized Ball curve, that is, bounding disk Wang-Bézier type generalized Ball curves with lower degree disk Wa...
