Acrolis Prime

For other uses, see **Acrolis (disambiguation)**.

**Acrolis Prime** (/æˈkrɑːˌlɪs/; *a-KRAH-lihs*)—sometimes simplified to **Acrolis** and poetically referenced as **Solis Acrolis**—was a G-type yellow dwarf star that served as the primary star of the Acrolis system. Like its system, Acrolis Prime was located in the eponymous Acrolis subsector, a sparsely populated subsector of the Outer Rim's Sanbra sector. Acrolis, a moon-sized waterworld, Force nexus, and fortress world, was the sole planet of the system.

For much of its recorded history, Acrolis Prime hosted the Acrolis system's Star Forge immediately outside its photosphere. This space station, similar to the Tulpaa and Makatak Star Forges, was a miniature replica of the ancient Rakata superweapon of the same name begun by Acrolian Rakata during the Rakatan Civil War that preceded the final collapse of the Infinite Empire. Though left unfinished for millennia, it was eventually completed during the last days of the Great Peace of the Republic and drew on Acrolis Prime for power in the manufacturing of starships for Acrolian Astroworks and the Acrolis Star Defense Force.

## Description

Moving down on the sequence, you'll find your G- and K-type dwarfs. These live for billions of years, which is a lot of time for life to emerge. Manda Prime's a main-sequence G; odds are your sun is a G or K too. Then you've got the M's, the red dwarfs. These live pretty much forever, bu they're awfully faint and cold for life.

Acrolis Prime was a fairly unspectacular example of a lower-mass main-sequence star, exhibiting such common traits as the presence of a hydrostatically equilibrious core and the nuclear fusion of hydrogen via the proton–proton chain sequence. As a G-type yellow dwarf star that straddled the line between G-type and K-type designations, Acrolis Prime exhibited an orange-red coloration in the visible light spectrum. The star generated enough warming radiation on the non-ultraviolet spectrum to permit the existence of liquid water on the surface of its planet Acrolis and little enough ionizing radiation to not destroy higher-order lifeforms found throughout the Acrolis system. However, like many K-type stars, it did produce higher-than-average amounts of X-rays and far ultraviolet radiation in the earliest days of its main-sequence period, such that the emergence of endemic lifeforms was delayed longer than normal for larger, heavier G-type stars.

## History

### Early history

Acrolian astronomers at the University of Acrolis believed Acrolis Prime to have accreted concurrently with the other stars of the stellar association that constituted the core holdings of the Acrolian Star Empire billions of standard years prior to the Battle of Yavin. According to the prevailing theory, an outlying pocket of the Hook Nebula sustained gravitational collapse due to shock waves generated by supernovae elsewhere in the nebula, disrupting the pocket's mechanical equilibrium and leading to hierarchical fragmentation into ever smaller concentrations of gas. The resultant infrared dark clouds of this emerging embedded cluster obscured heavy starburst as clumps of gas began to accrete into protostars and pre-main-sequence stars, one of which was the young orange-red dwarf Acrolis Prime.

The hottest and brightest of these protostars, the OB stars, emitted ultraviolet radiation that ionized the young embedded cluster into an H II region. The stellar winds, shock waves, and radiation pressure generated by these large protostars, coupled with the core-collapse supernovae that marked the end of their short lives, dissipated the unaccreted gas of their erstwhile embedded cluster into the depths of space. Though this simultaneously propelled chemically diverse elements into those circumstellar protoplanetary accretion disks that survived the period, establishing conditions conducive to the birth of metal-rich habitable planets, this loss of mass drastically altered the energy of the closed system and the gravitational balance of the region, leading to the decay of the star-forming embedded cluster and dispersion of its young surviving stars into the galactic field.

Some of these stars, still closely gravitationally bound to each other, remained part of the cluster, now defined as an open cluster, in which they had formed, while others, like Acrolis Prime, were ejected from the region in loosely bound packs called stellar associations. Through close gravitational encounters with larger stars in the cluster, Acrolis Prime and its stellar association were propelled in a trailing and coreward direction out of the Hook Nebula and into the region of space subsequently known as the Sanbra sector. Along with the stars of its stellar association, Acrolis Prime was among of those stars that retained its disk through the chaos of its natal cluster, and over eons, clumps of matter that formed in its accertion disk became the celestial bodies of the Acrolis star system.
