Peony Star in Barniske et al. (2008).[1]

Peony Star is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is English in modern astrophysics. It is the name of the star WR 102ka in constellation Sagittarius.


Concordance, Etymology, History

WR 102ka is a wolf-rayet star below visibility limit, so there are no cultural names.

Barniske, Oskinova and Hamann (2008)[1] note in their abstract

"A peony-shaped nebula around WR102ka is resolved at 24 μm by the Spitzer MIPS camera. We attribute the formation of this IR-bright nebula to the recent evolutionary history of WR102ka"

Mythology

The name was adopted by the IAU WGSN in 2026, as it has been in popular use among astrophysicists and listed in SIMBAD already.
