## Regional Information

### Galactic Region

Halo

Caphitis is one of the most extreme stellar objects in the entirety of the Thavma Assemblage. It is the most massive and brightest (bolometrically speaking) star in the entirety of Ambrosia. It is also one of the most unstable stars in existence, which results in it having one of the most significant pulsations in the entirety of Ambrosia. One pulsation lasts around 20 years.

Caphitis is located in the Dryas Cloud of the Ambrosia Galaxy, close to the Mid Arm. But if it were observed in 2000 CE, its visual magnitude would be above 24 (When it was a Wolf-Rayet star), which means it would likely not have been observed, and if it were observed at all, all the redshifting likely would've erased any significant things in its spectrum that would've given away its Wolf-Rayet identity.

## Properties

Caphitis's star class cannot be clearly described. It can be called a massive hydrogen-rich Wolf-Rayet star, or a Luminous Blue Variable. Whatever it is, it's big, hot, bright and not pleasant to be around.

Its solar wind, despite not being very fast, is very powerful and gives Caphitis one of the highest mass loss rates ever recorded. In short periods of galactic, Caohitis has lost a heavy leevl of its mass. Due to this extreme solar wind, it has a nebula around it. Caphitis's solar wind is also extremely opaque and makes the surface and radius hard to define.

Owing to its stupidly large mass, Caphitis has a lifetime of less than a million years, and sadly it is already dying.

## Variability

Being a Luminous Blue Variable, Caphitis is bound to have extreme pulsations. Here is a table that records several minimums and maximums observed.

 Deep maximum (Observed 97742 CE)

To conclude, we can see that Caphitis has clearly defined minimums and maximums, and many things change during those minimums and maximums. However, they are irregular.

## History

Caphitis started its life as a hot O0V star, that collapsed from a single large molecular gas cloud, floating around in the Dryas Cloud region. A mere 400,000 years later it developed signatures of heavy elements in its spectra which indicated that it was evolving, and getting brighter and cooler.

~100,000 years ago, or 500,000 years into its lifetime, enough nitrogen was present in Caphitis for it to become a WNh Wolf-Rayet star, similar to R136a1 when it was first discovered by humans. It was slowly moving off the main sequence.

### Discovery

At 10,294 CE, Caphitis was discovered as it was immediately noticed from afar due to its extreme brightness. It was given the designation AmbWR 1, the first Wolf-Rayet star discovered in Ambrosia, due to its immense brightness, being bright even through a giant cloak of dust that surrounded it.

Over the millenia, Caphitis would cool and enlargen and continue to lose mass, transforming it into an LBV, and this is where it is right now. (Caphitis could not become a red supergiant as it was too massive to expand this much) The increased brightness of Caphitis started to ionise all of the recently ejected matter to create a giant wind-blown bubble around it.

## Future

Caphitis only has around 30,000 years left as a LBV. After that it will quickly contract into a hydrogen-free WN Wolf-Rayet star, which will slowly contract and heat up. 250,000 years into the future, Caphitis will explode in a hypernova, sterilising everything in a 450 light year radius. The explosion site will most likely become a rich stellar nursery, with many forming stars. All that will remain in the center will be a black hole.

## Use

Caphitis has a very extensive Dyson swarm and produces about 0.054% of the AAUS's total Dyson sphere-derived energy. It needs to be constantly replaced though, due to the extreme stellar wind. This is easy because there is so much material near Caphitis. The swarm collects about 8.17e+31 Watts, or about 6% of Caphitis's total visible-light energy production. A Nicoll-Dyson beam is also under construction around this star, and it plans to send Caphitis's starlight to places where there is little to no light, such as around brown dwarfs or rogue planets, within a 4000 ly radius of the star.

In addition to this, 5 SICTIRIAD stations orbit the star distantly, collectively known as the Våldsam Stations. They ferry approximately a combined 30 trillion individuals per day.
