Azelfafage: the blue-white star of Cygnus

blue-white · Cygnus · π1 Cyg

Azelfafage is a blue-white star, the colour of the hottest, youngest suns in the constellation Cygnus, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 4.69 it is visible to the naked eye under a dark sky.

Most stars in the sky are anonymous points of light. Azelfafage is not. Some IAU-recognised names are ancient; others were adopted by the IAU only recently. Either way, the star already has a scientific identity, and a dedication attaches a human story to it.

What kind of star is Azelfafage?

Azelfafage is a blue-white subgiant. Its surface runs somewhere between 10,000 and 30,000°C, which is what gives it a blue-white cast. Colour in a star is a temperature reading rather than a decoration: the hot ones are blue and the cool ones red, the opposite way round to a kitchen tap.

It is spending its fuel at a rate the Sun never will. Most of the bright stars in familiar constellations are this kind, which is why the night sky looks younger and hotter than the average star actually is.

A star of this class gets tens of millions of years, against the Sun's ten thousand million.

It is a subgiant, caught in the short crossing between an ordinary life and a giant one. Its core has run out of hydrogen but its outer layers have not finished expanding, and astronomically this stage passes quickly.

Azelfafage barely moves against the background sky, which is mostly a statement about how far away it is. For every practical purpose, including yours, it is fixed.

The light you are looking at is old

Azelfafage is about 1,726 light years away, so the light reaching you now set out around 300. You are not looking at the star as it is. You are looking at the star as it was, and there is no way to see it any other way.

That delay is the part people find hardest and like most. A star is the one thing you can give someone that was already old before either of you was born and will outlast anything else you could have chosen.

It is comfortably visible without equipment on a decent night.

What does the name Azelfafage mean?

It bore the traditional name Azelfafage, derived from the Arabic al-sulaḥfāh, the tortoise, originally a name for Lyra that was misattributed to a star in Cygnus.

Name origin from English Wikipedia. AsterNym does not invent an etymology where none is recorded, and most stars in this catalogue have none: they carry modern names, or a catalogue designation and nothing older.

What could a Azelfafage dedication represent?

Azelfafage is especially meaningful for someone who:

  • · Deserves something older than any gift shop
  • · Marks a beginning, an anniversary or a promise
  • · Is remembered every time you look up
  • · Has a light you want recorded somewhere permanent

Where can you see Azelfafage?

It is easy to see from most of the Northern Hemisphere. It can also appear from lower southern latitudes, but it never rises for observers south of about latitude 39°S. It passes directly overhead at latitude 51°N. It stands highest at midnight in August, so August and September evenings are the best time to look. At magnitude 4.69 it is a naked-eye star only under a dark sky, binoculars make it certain.

Azelfafage belongs to Cygnus.

What does Azelfafage mean in astrology?

The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Azelfafage, and we don’t invent lore where none exists. What astrology can still read is the star’s real position, below.

Projected onto the zodiac the way fixed-star astrology reads any star, Azelfafage stands at 28° Pisces at the J2000 epoch, and the Sun passes that degree around 18 March in the years around 2000. Fixed-star longitude shifts slowly against the tropical zodiac because of precession, about one degree every seventy-two years, so a natal conjunction must be calculated for the birth year rather than read off this J2000 value or a calendar date.

Traditional interpretations, not facts or predictions. The position and dates are computed.

Cygnus, drawn from catalogued positions: brighter stars are larger, and the colours follow spectral type. North is up and east is left, the sky-chart convention, so it is mirrored against a map of the ground. The joining lines are one drawing convention among several; the IAU fixes the boundaries, not the figure.
AsterNym dedications are personal commemorative records: they are not recognized by the International Astronomical Union, do not change scientific catalogue names, and do not confer ownership of a star.
