A
Named stars

Aldebaran →

Also: Alpha Tauri · the Follower

The IAU-recognised proper name for Alpha Tauri, a bright star in Taurus.

Word origin, evidence & sources
Word origin · etymology
Arabic al-dabarān.

A Smithsonian history of Arabic star names, citing al-Sufi, explains the root as ‘to follow’ and relates it to following the Pleiades. Ptolemy instead calls the reddish Hyad ‘the Torch’ in the cited translation.

How we know · epistemology
Astronomical identification; historical and interpretive records kept separate.

The IAU identifies Aldebaran as Alpha Tauri. The Torch/Mars attribution belongs to Ptolemy’s reported inherited observations and must not be recast as a Brady-style angular reading.

Named stars

Antares →

Also: Alpha Scorpii · heart of the Scorpion

The IAU-recognised proper name for Alpha Scorpii A, a bright stellar component in Scorpius.

Word origin, evidence & sources
Word origin · etymology
Ancient Greek Antares.

Etymonline analyses the name as contracted anti-Ares, ‘rival of Mars’, in reference to its red appearance. This is name history, not a calculation rule.

How we know · epistemology
Astronomical identification; historical and interpretive records kept separate.

The IAU table identifies Antares with Alpha Scorpii A. Ptolemy’s Mars-with-lesser-Jupiter likeness is a historical, source-specific lens; modern parans only establish paired local angles.

Named stars

Fomalhaut →

Also: Alpha Piscis Austrini · mouth of the Southern Fish

The IAU-recognised proper name for Alpha Piscis Austrini A, a bright stellar component in Piscis Austrinus.

Word origin, evidence & sources
Word origin · etymology
Scientific Arabic fam al-hūt.

The name means ‘mouth of the [Southern] Fish’. The IAU notes many historical spellings and names, so this entry avoids treating one form as exhaustive.

How we know · epistemology
Astronomical identification; historical and interpretive records kept separate.

The IAU list attaches Fomalhaut to Alpha Piscis Austrini A. Ptolemy’s Venus-and-Mercury likeness for the bright mouth star is a comparative historical attribution, not a promised modern paran meaning.

R
Named stars

Regulus →

Also: Alpha Leonis · the heart of Leo

The IAU-recognised proper name for Alpha Leonis A, a bright star in Leo.

Word origin, evidence & sources
Word origin · etymology
Modern Latin regulus.

The name means ‘little king’, a diminutive of Latin rex; this lexical fact does not prove a doctrine of kingship.

How we know · epistemology
Astronomical identification; historical and interpretive records kept separate.

Regulus A is a named stellar component in the IAU table. Ptolemy’s Mars-and-Jupiter comparison concerns the star at Leo’s heart in his own framework, not a modern paran recipe.

S
Named stars

Sirius →

Also: Alpha Canis Majoris · Dog Star

The IAU-recognised proper name for Alpha Canis Majoris A, the bright star in Canis Major used here as a selectable astronomical target.

Word origin, evidence & sources
Word origin · etymology
Ancient Greek Seirios.

LSJ records seirios as the dog-star and ‘the scorcher’; the name’s older derivation is not settled here.

How we know · epistemology
Astronomical identification; historical and interpretive records kept separate.

The catalogue models the direction of the named Sirius target; a component name does not imply that the event solver models its binary orbit. The Greek name and Ptolemaic comparison are historical records, not measured personal effects.

Named stars

Spica →

Also: Alpha Virginis · ear of grain

The IAU-recognised proper name for Alpha Virginis Aa, a bright stellar component in Virgo.

Word origin, evidence & sources
Word origin · etymology
Latin spica.

The Latin noun denotes an ear or spike of grain. It names the star but does not itself prescribe an interpretive outcome.

How we know · epistemology
Astronomical identification; historical and interpretive records kept separate.

The IAU list attaches Spica to Alpha Virginis Aa. Ptolemy’s Venus-with-lesser-Mars likeness is a source-specific comparison, not evidence for a fixed result when a modern tool finds an angular event.
