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.
