An A-type main-sequence star (A V) or A dwarf star is a main-sequence (hydrogen-burning) star of spectral type A and luminosity class V. These stars have spectra which are defined by strong hydrogen Balmer absorption lines.
Mohammad Al Achsasi Al Mouakket (محمد الاخصاصي الموقت / ALA-LC) was an Egyptian astronomer whose calendarium and catalogue of stars, entitled Durret al Muddiah Fih al Aamal al Shamsiah (Al-Durrah al-muḍīyah fī al-ʻamāl al-shamsīyah, "Pearls of brilliance upon the solar operations"), was written at Cairo about 1650.
The traditional star name Albulaan refers to two stars in the Aquarius constellation.

The apparent magnitude (m) of a celestial object is a measure of its brightness as seen by an observer on Earth, adjusted to the value it would have in the absence of the atmosphere.
Aquarius is a constellation of the zodiac, situated between Capricornus and Pisces.
A Bayer designation is a stellar designation in which a specific star is identified by a Greek letter, followed by the genitive form of its parent constellation's Latin name.
The Bright Star Catalogue, also known as the Yale Catalogue of Bright Stars or Yale Bright Star Catalogue, is a star catalogue that lists all stars of stellar magnitude 6.5 or brighter, which is roughly every star visible to the naked eye from Earth.
The Catalogue of Fundamental Stars is a series of six astrometric catalogues of high precision positional data for a small selection of stars to define a celestial reference frame, which is a standard coordinate system for measuring positions of stars.
The celestial equator is a great circle on the imaginary celestial sphere, in the same plane as the Earth's equator.
Chinese (汉语 / 漢語; Hànyǔ or 中文; Zhōngwén) is a group of related but in many cases mutually unintelligible language varieties, forming a branch of the Sino-Tibetan language family.

In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
In both astrology and historical astronomy, the zodiac (Greek: ζῳδιακός, zōidiakos) is a circle of twelve 30° divisions of celestial longitude that are centered upon the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year.
