This effort seeks to adjust the detection limit from approximately 0.6 Jupiter masses to around 0.3–0.4 Jupiter masses. Subsequent JWST observations aim to verify or dismiss the existence of S7. Furthermore, the Cycle 2 program may clarify S7's association with
Fomalhaut and identify additional planets hinted at by the complex disk structure revealed in the MIRI results, as outlined by the authors.

detection of
Fomalhaut b at 0.4 μm. They modeled the optical detection and infrared upper limits for Fomalhaut b, showing that Fomalhaut b's emission can be completely explained by starlight scattered by small dust and arguing that this dust surrounds an unseen planetary-mass object. Thus, they consider Fomalhaut b to plausibly be a "planet identified from direct imaging" even if Fomalhaut b is not, strictly speaking, a directly imaged planet insofar as the light does not come from a planetary atmosphere.

Fomalhaut b would have had to be dynamically scattered by a more massive, unseen body located at smaller separations. Several ground-based observations have searched for this hypothetical
Fomalhaut "c", but have yet to find it. At very small, Solar-System-like scales, any additional companions must have a mass less than thirteen times that of Jupiter. At slightly larger scales, comparable to the locations of the planets around

Fomalhaut b was thought to be a plausible explanation for Fomalhaut's eccentric debris ring, measurements in the Kalas et al. paper hinted that it was moving too fast (i.e. not apsidally aligned) for this explanation to work. Finally, researchers analyzing September–October 2011 data from the

Kalas remarked, "It's a profound and overwhelming experience to lay eyes on a planet never before seen. I nearly had a heart attack at the end of May when I confirmed that
Fomalhaut b orbits its parent star." In the image, the bright outer oval band is the dust ring, while the features inside of this

In the latest observations using NIRCam and NIRSpec, researchers identified 10 sources within the dusty rings of the
Fomalhaut system. These JWST observations neither confirm nor reject the existence of the "new" Fomalhaut b, S7. The upcoming Cycle 2 follow-up program aims to determine whether S7 is
389:, any additional planets of Fomalhaut must have masses below about 2 to 7 Jupiter masses. A gaseous planet in an orbit like Fomalhaut b could have formed in situ if it coalesced from small pebble-sized objects that rapidly formed into a protoplanetary core which in turn accreted a gaseous envelope.
297:
In the discovery paper, Kalas and collaborators suggested that
Fomalhaut b's emission originates from two sources: from circumplanetary dust scattering starlight and from planet thermal emission. Here, the former explains most of the 0.6 μm brightness and planet thermal emission contributes to

The existence of a massive planet orbiting

data obtained in 2013 and 2014, published in 2020, found that

and collaborators again recovered
Fomalhaut b. However, analysis of Fomalhaut b's astrometry showed that the object has a high eccentricity (e = 0.8), its orbit (projected on the sky) crosses the plane of Fomalhaut's debris ring, and thus it is unlikely to be the object sculpting the debris ring's
384:
Based on the (now disproven) assumption that Fomalhaut b was a gaseous planet, the existence of additional planets closer to the star had been postulated. Fomalhaut b would be orbiting its host star at a wide separation, where forming massive planets is difficult. To explain its current location,

However, Fomalhaut b should be detectable in space-based infrared data if it is a planet and has a mass between 1–3 times Jupiter's mass. On the contrary, observations from the infrared-sensitive Spitzer Space Telescope failed to detect Fomalhaut b, implying that Fomalhaut b has less mass than

expected. The initial theory was that a massive planet on a wide orbit but located interior to this debris ring could clear out parent bodies and dust in its vicinity, leaving the ring appearing to have a sharp inner edge and making it appear offset from the star.

The revival of the claim that Fomalhaut b was (possibly) a planet after it had been discounted led some to nickname the object a "zombie planet", although this is a non-technical term used in press material and does not appear in any peer-reviewed manuscript.

for Fomalhaut's debris ring suggested an alternate hypothesis: that the ring could be shaped by much smaller, shepherding planets, neither of which needed to be Fomalhaut b. These results invoked skepticism about Fomalhaut b's status as an extrasolar planet.

The planetary hypothesis has since fallen out of favor; more gathered data suggested a dust or debris cloud is far more likely, and the object was placed on an escape trajectory. In 2023, a team of researchers used the
