rotated 25° clockwise.
NGC 7419 is a young
open star cluster, in the constellation Cepheus, at a distance of
7,500 to 11,000 light years. The cluster's age is from 10 to 15
million years. Its location, behind dark nebulae and molecular
clouds, heavily reddens the color. Although NGC 7419 is dominated by
blue stars, the foreground galactic extinction almost completely
block the blue light.
The enigmatic open cluster NGC 7419
Amparo Marco & Ignacio Negueruela
We determine the distance and the age of the open cluster NGC 7419
using accurate photometry and spectroscopy. We analyze spectra for a
great number of members; concluding that NGC 7419 has one of the
highest Be fractions among Galactic open clusters. We also confirm
that the cluster contains five red supergiants but there are no blue
supergiants. Both effects may be related to fast rotation, but high
Be content and high RSG content do not always go together.
