Web14 lug 2015 · The HL Tau disk is viewed on the sky inclined with respect to our line of sight (defined as for face-on) and rotated by an amount defined by the P.A. measured from north to east. In order to constrain these parameters we first followed the standard practice of fitting a Gaussian to the visibility data. WebHL Tau is located in the centre of the image. The star is surrounded by a dusty disc tilted to the line of sight and not visible here, but its boundary is indicated by the white ellipse. The arrows show the direction of jets of hot gas emitted from the forming star system (Image credit : VLA + Pie Town antenna). borderlands vs goty edition xbox 360
