A stellar association is a very loose star cluster, looser than both open clusters and globular clusters. Stellar associations will normally contain from 10 to 100 or more stars. The stars share a common origin, but have become gravitationally unbound and are still moving together through space. Associations are primarily identified by their common movement vectors and ages. Identification by chemical composition is also used to factor in association memberships.
Alpha Trianguli is a spectroscopic binary star in the constellation of Triangulum. Based on parallax measurements obtained during the Hipparcos mission, it is approximately 63.3 light-years distant from the Sun. The brighter or primary component is named Mothallah.
Tau1 Arietis, Latinized from τ1 Arietis, is the Bayer designation for a triple star system in the northern constellation of Aries. Based upon an annual parallax shift of 6.1786 mas, it is approximately 530 light-years distant from Earth. The combined apparent visual magnitude is 5.27, making it faintly visible to the naked eye.
HD 103079 is a class B4V star in the constellation Musca. Its apparent magnitude is 4.89 and it is approximately 362 light years away from Earth based on parallax. It is a member of the Lower Centaurus–Crux subgroup of the Scorpius–Centaurus association, a group of predominantly hot blue-white stars that share a common origin and proper motion across the galaxy.
Zeta2 Muscae, Latinized from ζ2 Muscae, is a star in the southern constellation of Musca. Its apparent magnitude is 5.16. This is a white main sequence star of spectral type A5V around 330 light-years distant from Earth. Like several other stars in the constellation, it is a member of the Lower Centaurus–Crux subgroup of the Scorpius–Centaurus association, a group of predominantly hot blue-white stars that share a common origin and proper motion across the galaxy. It is part of a triple star system with faint companions at 0.5 and 32.4 arc seconds distance. The former is an infrared source, the latter has a visual magnitude of 10.7.
