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

Astronomical identity

Aldebaran is the IAU proper name for Alpha Tauri (HR 1457), in Taurus. Unlike entries where the official table has a component letter, this row has no component field.

A historical association with the Hyades is not a substitute for the exact target definition used by an event solver.

Name and historical record

A Smithsonian study of Arabic star names, citing al-Sufi, derives Aldebaran from a root ‘to follow’ and connects it with the Pleiades. Ptolemy’s translation gives a different positional description: the bright, reddish Hyad called ‘the Torch’.

These records let a visitor distinguish Arabic name history from the Greco-Roman positional description.

Ptolemy’s named comparison

For the bright, somewhat reddish Hyad called the Torch, Ptolemy reports a Mars-like temperature. The wording is directly evidenced, though it calls the star by description rather than the later Arabic-derived name.

The dataset preserves this identity link cautiously and does not expand it into ‘Mars themes’ or a generic warning.

Use in a modern paran result

For Aldebaran, use the table to confirm the two event names and whether either timestamp lies in search padding at the edge of the 24-hour window. This makes a near-boundary match auditable.

Brady’s public teaching presents modern parans as an angle-based symbolic synthesis. Keep that method label beside the row and offer Ptolemy’s Mars-like ‘Torch’ comparison as a separate historical study card.

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.
