R Sculptoris – Slicing through a 3D ALMA view of the material around the red giant star R Sculptoris

10 comments

Like: www.facebook.com Observations using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed an unexpected spiral structure in the material around the old star R Sculptoris. This spiral is probably caused by a hidden companion star orbiting the star. This new ALMA video shows a series of slices through the data, each taken at a slightly different frequency. These reveal the shell around the star, appearing as a circular ring, that seems to gets bigger and then smaller, as well as a clear spiral structure in the inner material that it best seen about half-way through the video sequence.

Jerczey: Our Sun doesn’t do anything like this. This star is near the end of its life and is throwing off material at a great rate, many orders of magnitude greater than CMEs.

Took me a sec to realize how they managed to get 3D structure in something over a thousand light-years away. Then I saw: “each slice was taken at a different frequency.” Bingo! It’s an expanding shell, so each “layer” relative to our line-of-sight is moving at a slightly different red- / blue-shift. Science is amazing…

it looks like a biological cell, nucleus and all

I wonder if our star Sun does the same too…
I thought this illustrations might have captured how CME’s are perhaps accumulated on the outer regions of a solar system

I came from a site which called this a “spiral structure”. Maybe it looked like one in a snap shot.

Truly stunning. It is amazing how much is still not well-understood when it comes to stellar dynamics…we are living in exciting times indeed when it comes to astronomy, cosmology and astrophysics. Thank-you for sharing!
