描述U Antliae - ALMA - Eso1730a.tif |
English: Delicate bubble of expelled material around the cool red star U Antliae
This ALMA image reveals much finer structure in the U Antliae shell than has previously been possible. Around 2700 years ago, U Antliae went through a short period of rapid mass loss. During this period of only a few hundred years, the material making up the shell seen in the new ALMA data was ejected at high speed. Examination of this shell in further detail also shows some evidence of thin, wispy clouds known as filamentary substructures. Coordinates Position (RA): 10 35 12.87 Position (Dec): -39° 33' 44.99" Field of view: 2.18 x 2.18 arcminutes Orientation: North is 0.5° right of vertical Colours & filters Band Wavelength Telescope Millimeter 230 GHz 1.3 mm Atacama Large Millimeter/submillimeter Array Band 6. |
