View Full Version : Discussion: Glimpse at the Envelope of a ...

SUMMARY: Japanese astronomers have used the 8.2m Subaru Telescope to get detailed images of the envelope of gas and dust surrounding a very young star in M17. This envelope extends in a symmetrical butterfly shape about 150 times the size of our Solar System. This image hints at the process of how matter streams into the protostellar disc during early formation of a new star.

This a rather ingenious study design with equally impressive results. Using this method should yield a wealth of data on how solar systems form.

This is an interesting story, especially two observations:

1. "Around the equator of the protostar, the torus of dust and gas increases in thickness farther way from the star."

2. "Thin cone-shaped shells of material extend away from both poles of the star."

This early structure in a forming star is intriguing. It suggests the possibility that the star may be forming on a pre-existing object.

With kind regards,
