Dear those who send out school newsletters. I do not want a link to a PDF of a bunch of AI or PowerPoint flyers with QR codes. I want plain text and links in the email. If you must, you can bold some of the text. They may be boring, but at least I can find the information when I need it.

It was a small search, only 4 WDs. And we weren't gifted with a resolved planet this time. But that doesn't mean we shouldn't keep looking. We showed that JWST allows us to find nearby giant planets around WDs. We just have to look twice to rule-out those pesky galaxies lurking in the background.

We were really expecting to find planets with this tiny survey of 4 WDs and we still have 2 unresolved candidates left to confirm. For resolved planets we were able to rule-out planets as small as half the mass of Jupiter out to hundreds of au.

However, earlier @johndebes.bsky.social showed that two of the white dwarfs are too bright in the mid infrared, consistent with a 1.4 Jupiter-mass, unresolved planet. For one of those stars, our data show the excess also moves with the WD. So it is bound to the WD and could be a planet.

Here is the key image from the paper. The red cross marks the candidate planet and the green triangle is on top of the white dwarf star. The WD moves several pixels, the red dots do not. Those red dots are likely distant, background galaxies.

Sadly, in a paper by @fergalm.bsky.social, @johndebes.bsky.social and others, arxiv.org/pdf/2512.081.... JWST shows that those two spots do not move across the sky like the white dwarf star. The separation between the spot and the star (green triangle) change between the two observations. Boo!

If they are planets, they would be bound to the white dwarf star and would move across the sky in the same way that the nearby white dwarf does. So we asked for second observations of the white dwarf to see if the spots moved too.

Remember those red spots next to two white dwarf stars that looked like possible planets in JWST images that we found? We just had a paper accepted that continues to tell the story.

NEWS: Researchers used the James Webb Space Telescope to refine the orbit of two Wolf-Rayet stars—named for the Egyptian god of chaos—to a lengthy 190 years and confirmed a third star carves their ongoing carbon dust ejections. 🔭 🧪 (1/6) 🧵
Four dust shells expand away from three central stars that appear as a single pinpoint of light. The innermost shell is smallest, like the size of a thumbprint, and brightest. It is yellow and forms a backward lowercase e. A line at 3 o’clock swoops to the bottom-left in an arc that ends at 8 o’clock. A second line at 9 o’clock dips down to start, but then goes straight up, angling around the top. The second shell, about the size of a fist, is orange and has looser arcs. One appears from 4 to 7 o’clock. A brighter orange triangle appears from 10 to 12 o’clock. Its outer edges overlap, forming a rough circle. The third shell extends almost to the edges and is semi-translucent red, with similar arcs and a darker red line that also forms a faint triangle at top left. The widest shell is faintest and at the edges. A semi-transparent blue appears across the scene. A larger foreground star with spikes is at bottom left, and more distant stars and galaxies are strewn across the black expanse of space.
