Time to update the Gas Giant Portrait I created, now including the new versions of Saturn and Uranus I recently processed.

Jupiter is next on the list to be updated :)

The raw data look like messy interferograms that are hard to understand by eye - and we enhance these data to restore beautiful images of the environment of the black hole in NGC 1068, Jupiter's moon Io, and a dusty binary system WR 137.

Yes, JWST should be able to observe this in the IR similarly to LBTI and VLT/SPHERE, but at a bit lower spatial resolution. It would be more sensitive than these observations at wide separations (especially beyond the separation of planet b), but may have poorer performance at close separations

Thanks!

We don't detect a significant Hα accretion signal from CC1, but see it clearly at L' and also in weaker detections at Ks and z'. It appears to be too red for scattered starlight, so we propose it may be a 2nd protoplanet, more embedded in dust. Read our paper here: iopscience.iop.org/article/10.3...

This is very cool! I have used PCA to subtract stellar PSFs for high-contrast (circumstellar) imaging in a similar fashion, but I had never considered a solar-system application like this.

There's this analytical result from the 2nd Ed. Of Stellar Interiors by Hansen, Kawaler, and Trimble, Ch. 9 (plus an aside on the implications for life on Earth!)
