Necklace is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is English language in modern astrophysics. It is the name of the star IRAS 19417+1701 (17.7 mag in G) in constellation Sagitta.
Concordance, Etymology, History
The reason for the name in given in Corradi et al. (2011)[1]:
Along the orthogonal direction, faint emission traces a roughly cylindrical structure ending in two slightly brighter, irregular ‘polar’ caps at about 1 arcmin from the central star. As typical of this kind of structure (Gonçalves, Corradi & Mampaso 2001), the ring’s knots and their faint outward tails, as well as the polar caps, are most evident in the low-ionization [N II] emission. This striking [N II] morphology led to the object’s nickname, ‘the Necklace nebula’ (Sabin et al. 2010, in preparation).
Mythology
no mythology.
IAU Working Group on Star Names
The name was adopted by the IAU WGSN in 2026, as it has been in popular use among astrophysicists and listed in SIMBAD already.
