The Keith star system (AAC-2) is a binary star system was discovered in Aug-2022, watching behaviors of closely positioned blue giant stars, Camille (AAC-2-1 / HD 162678) and Kyle (AAC-2-2 / HD 162679). The star system is located on the star dome of the Ascendents Sphere (AAC-1) and also is at the middle of Ptolemy's Cluster (M 7 / AAC-7).
For a star as Camille (AAC-2-1), whose day lasts for over 2 Earth-months, Kyle (AAC-2-2) scrambling around to accomplish an entire revolution in a 16 Earth-hour day may seem foolish. Sometimes they space each other. Neighbor stars sort-of attract them, but not so much as they are a lot more distant; others' gravitational pull, temperature, and light doesn't really have the same meaningful and direct effect.
The, "year length," for the stars to orbit each other remains unknown, orbits of binary stars have been at the edge of discovery even for the Alpha Centauri system stars (consensus for Rigil Kentaurus and Toliman orbit is every 79 years), however; for Proxima, .2 light years is a fairly significant distance for an orbit radius and is calculated at around 430 Neptune orbits of 165 Earth-years. Some orbits are faster than others, but with using that information, if Camille and Kyle actually orbit, it might be estimated nearly every 700 Neptune orbits (once roughly every few hundred thousand Earth-years), because if circular it has to travel about 1.88 light years; therefore the models that predict tidal lock can't be true, because it would be impossible for the stars to complete their orbit in only 72 days as they would have to be traveling faster than the speed of light.
There's an understanding that even Proxima causes precession (wobble) for the rest of the Alpha Centauri system, in 2016 Ken Croswell for New Scientist relayed from Pierre Kervella at the Paris Observatory in France, "that’s the reason why it is possible now to be sure that there is a gravitational link between Proxima and Alpha Centauri." Moreover, "the work reveals Proxima’s orbit for the first time. The star revolves once every 550,000 years on an elliptical path." Compared with Proxima being a tenth the size of Rigil Kentaurus, Kyle is about two-thirds the size of Camille and is considerable mass for their system's barycenter.
Camille and Kyle are only 0.3247 light years (20,534 AU) apart, where-as Alpha Centauri (one of the brighter stars in Earth's night sky) is 4.367 light years away, over 13 times more distant. Neighboring stars are everywhere continuing about their orbits, there is a balance and they never get closer or more distant than their orbits allow. No parts of any other known stellar orbits extend to the Keith star system or get closer than the two stars. Alpha Centauri is a much dimmer, smaller, and colder star system than Keith. The two closest stars of α Cen are very close, 23 AU from Rigel Kentaurus to Toliman (α Cen B) is only the distance from Sol to Uranus.
Way back in August of 1982, research of HD 162679 (Kyle) was provided by NASA Astrophysics Data Systems and published to, Publications of the Astronomical Society of the Pacific p, Vol. 94, p. 692-694 (1982). H.G. Luna doesn't seem to mention Camille (HD 162678) on the opposite side of Kyle. (Kyle is closer to Sol, Camille is almost eclipsed, closer to the outside of the Ascendents Sphere [AAC-1]). At the time, maybe in an earlier star catalog, Kyle's closeness to Camille (HD 162678) star hadn't actually been discovered yet. The article itself confirmed variable polarization which had suggested it may be part of a binary system, "we conclude that while intrinsic variable polarization has been found in HD 162679, there is no satisfactory conclusion about its nature," and continued saying, "more spectroscopic, polarimetric, and photometric data with good time resolution are needed to check if a close binary system of short period is responsible for the observed variable polarization."
It's rare for small blue giants/super giants to revolve slowly, when comparing to other blue stars, Camille (class B9II) spins less, more like a miniature version of blue supergiant Rigel (ß Orion) (class B8I-a), where-as similar in luminosity, day-length, and surface temperature, Kyle (class B9V) is more like blue giants Algol (class B7V) and Regulus (B8IV).
It can be love/hate, because the two binary stars can't escape each other, however; there is peace in knowing that for hundreds of millions of years they are going to shine together, and comfort in knowing they share a connection and have a relationship others wouldn't understand. Even though it's difficult not to wonder if and how they could ever break orbits, there doesn't really seem to be any doubt in expecting for the stars of Keith to keep revolving.
The neighbor stars are not nearly as close, but they still try to throw around their weight. Maybe other stars seem jealous they don't have a stellar companion that is so bright and so close, and they are envious of spectacular views from the Camille and Kyle; because as mentioned not only are the two stars in the center of Ptolemy's Cluster (M 7 / AAC-7), the star system is also directly on the boundary of the Ascendents Sphere (AAC-1).
While having more depth and being twice as luminous of a star, it isn't always about being hot on the surface even though Camille's surface temperature of 10,300 K is twice as hot as Sol. Somehow, for Keith's smaller star being almost half as luminious, maybe all that extra energy from spinning, seeming denser, and having less surface area are reasons why Kyle at 10,700 K is even a little bit hotter. For being so hot, they both actually are really cool stars (there are distant fast-burning stars with surface temperatures over 200,000 K). Compared with Sol's radius, they are 5.6 rSun (Camille) and 3.6 rSun (Kyle). Both stars are very bright -- Camille is 209x more luminous than Sol, Kyle is 109x more luminious than Sol.
Days revolve slowly for Camille and Kyle revolves over 108 times faster. Every 72 Earth-days, there is a best day. Every 16 Earth-hours there is a best hour; that is true even during their system's 72 Earth-day birthday (possibly once every few hundred thousand Earth-years [if it's also a best day]). Like for the Moon to a place on Earth, there's always a leave and an approach, a waning and a waxing, a sunset and a sunrise. Losing and winning is a cycle of existence, stars repeat their orbits and revolutions. Camille is a brighter and bigger star with almost twice the depth, as Kyle revolves reflecting changes all around the galaxy. Maybe they both have turns being right. As for what happens after hundreds of millions of years, see it the right way and it'll also go right.
If wondering why the larger star is Camille (AAC-2-1) and Kyle (AAC-2-2) is the smaller star, that actually wasn't going to be the reality, except before typing the names, they were switched at the last second, because as Kyle Keith's journey has also led to the incredible discovery of AAC-1 Ascendents Sphere [leading to the development of the Ascendents Astronomy Catalog (AAC)]; that while the blue giants burn 100x faster than the sun, it was decided for the remainder of the two stars' 100+ million year life expectancies (and forever after that), with the greater interest and presence for astronomers, Camille should be the bigger, brighter, better-documented, and first-mentioned Keith star. The stars' close proximity to each other raises the probability for the fate of the stars to nova, or because of their current gravitational role, supernova.
