Is Achernar a white dwarf?

Although Achernar is a massive star, it is still young enough to be fusing hydrogen into helium in its core and may be small enough to evolve off the sequence as a massive white dwarf like Sirius B….Achernar.

Like so many others of the nighttime sky, Pollux is a typical red giant that is quietly fusing helium into carbon and oxygen in its deep core.

Where did the name of the star Acamar come from?

The name Acamar is from the Arabic آخِر النَّهْر ( Ākhir an-nahr) which means the end of the River. Ptolemy described Acamar (θ Eridani) as a first-magnitude star and said it was at the end of the River. But due to precession of the equinoxes, he could not see the brighter star Achernar (α Eridani), at the end of our River.

How big is the fixed star Acamar in magnitude?

Fixed star Acamar, Theta Eridani, is a 3.2 magnitude double star in the River, constellation Eridanus.

How big is Acamar compared to the Sun?

Acamar has a mass of 2.6 solar masses and a radius 16 times that of the Sun. With an effective temperature of 8,200 K, it shines with 145 solar luminosities. With a projected rotational velocity of 70 km/s, the star takes 569 days to complete a rotation.

How is Acamar related to the other Far Realms?

Acamar and the other Far Realm–infested stars of Realmspace were somehow related to the Eldest. Acamar’s hunger was endless, and when its influence on Toril was at its peak, it sent its agents, the Maws of Acamar, to devour everything they encountered in their path to sate the hunger of the dead star.
