APOD: GW Orionis: A Star System with Rings... (2020 Sep 29)

Post by APOD Robot » Tue Sep 29, 2020 4:09 am

Image GW Orionis: A Star System with Titled Rings

Explanation: Triple star system GW Orionis appears to demonstrate that planets can form and orbit in multiple planes. In contrast, all the planets and moons in our Solar System orbit in nearly the same plane. The picturesque system has three prominent stars, a warped disk, and inner tilted rings of gas and grit. The featured animation characterizes the GW Ori system from observations with the European Southern Observatory's VLT and ALMA telescopes in Chile. The first part of the illustrative video shows a grand vista of the entire system from a distant orbit, while the second sequence takes you inside the tilted rings to resolve the three central co-orbiting stars. Computer simulations indicate that multiple stars in systems like GW Ori could warp and break-up disks into unaligned, exoplanet-forming rings.

Know the quiet place within your heart and touch the rainbow of possibility; be
alive to the gentle breeze of communication, and please stop being such a jerk.

I've been trying to see the titles on the rings. That would be unusual indeed.

Yes, thank you. That typo has now been fixed (Titled --> Tilted). I apologize for the oversight.

The YouTube video (as of 10:00 a.m. EDT) has the same typo.

No planets for you, GW Orionis. The eccentric orbit of the third star is really messing things up.

It might be more the size of GW Ori C's orbit that affects planet formation. If it were closer to A and B, or significantly further away, then there might be room for planets-as-we-know-them to form. Going by the video, though, the only planets to form from this are more likely to be way, way out; is there such a thing as "Frozen Jupiters"? And it's a young system — none of the stars are even on the main sequence yet — with all elements over the mass of our sun. That's going to cut the main sequence lifetime down by quite a bit.
