Arcalís: the warm orange star of Boötes

warm orange · Boötes · HD 131496

Arcalís is a warm orange giant, far along its stellar life in the constellation Boötes, one of the stars with a proper name recognised in the IAU Catalog of Star Names. At magnitude 7.80 it is a binocular or telescope object.

Most stars in the sky are anonymous points of light. Arcalís 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.

J2000 catalogue coordinates that can be independently cross-checked against astronomical databases. A planetarium app showing coordinates of date will differ slightly, because proper motion and precession move a star’s apparent position over time.

What kind of star is Arcalís?

Arcalís is an orange star. Its surface runs roughly 4,000 to 5,000°C, cool enough that the light carries a visible orange. 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.

Nothing of this kind has ever died of old age, anywhere, because the universe is not old enough yet. Every one that has ever formed is still burning.

A star of this class gets twenty to fifty thousand million years, far longer than the universe has yet existed.

Arcalís drifts about 5.7 arcseconds a century against the stars behind it. Slow by any human measure, and still enough that the sky your distant descendants see will not be the one in your photographs.

The light you are looking at is old

The light arriving from Arcalís tonight left in about 1667, some 359 years ago. Everything that has happened since, every person you have heard of from the last few centuries, happened while it was in transit.

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 sits at the edge of what an unaided eye can do, so finding it is a deliberate act rather than an accident.

What could a Arcalís dedication represent?

Arcalís 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

Dedication idea

“For the one I think of when I find Boötes in the sky.”

Where can you see Arcalís?

It sits 18° north of the celestial equator, so it clears the horizon everywhere short of latitude 72°S, in practice, every inhabited latitude on Earth. It passes directly overhead at latitude 18°N. It stands highest at midnight in May, so May and June evenings are the best time to look. At magnitude 7.80 it sits below naked-eye reach; binoculars or a small telescope will find it.

Arcalís belongs to Boötes.

What does Arcalís mean in astrology?

The classical fixed-star tradition: Ptolemy, the medieval Behenian lists, Robson’s 1923 compilation. Is silent on Arcalís, 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, Arcalís stands at 4° Scorpio at the J2000 epoch, and the Sun passes that degree around 24 October 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.

Boötes, 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.
