FITS images of SAO 206462
Listed in IVOA Registry (Virtual Observatory)
In the early stages of planetary system formation, young exoplanets gravitationally interact with their surrounding environments and leave observable signature on protoplanetary disks.
Description
Among these structures, a pair of nearly symmetric spiral arms can be driven by a giant protoplanet. For the double-spiraled SAO 206462 protoplanetary disk, we obtained three epochs of observations spanning 7yr using the Very Large Telescope's SPHERE instrument in near-infrared J-band polarized light.
By jointly measuring the motion of the two spirals at three epochs, we obtained a rotation rate of -0.85+/-0.05 deg per year. This rate corresponds to a protoplanet at 66+/-3au on a circular orbit dynamically driving both spirals. The derived location agrees with the gap in ALMA dust-continuum observations, indicating that the spiral driver may also carve the observed gap.

What is more, a dust filament at ~63 au observed by ALMA coincides with the predicted orbit of the spiral-arm-driving protoplanet. This double-spiraled system is an ideal target for protoplanet imaging.
