  Christian Mayers Doppelsternverzeichnis
Gamma Arietis, Gamma Virginis) sind beide Komponenten nahezu gleich hell, so dass eine Entscheidung welche Komponente der Hauptstern und welche der Begleiter ist, schwer zu treffen ist.
Doppelsterne nennt man diejenigen Sterne, welche sich mit bloßem Augen einzeln, durch minder oder mehr vergrößernde, oft nur durch sehr vollkommene Fernröhre aber, entweder aus zwei gleich großen, oder ungleich großen Sternen, die nur einige Sekunden auseinander zu stehen scheinen, zusammen gesetzt sich darstellen.
Wie bereits bei Alpha Arietis gibt er den Begleiter mit einer Helligkeit von 9 mag an.

I estimated that most came from near Gamma Arietis region, but that my estimate may have been off by 5 degrees or more.
Also, that the brighter meteors seemed to come from near Gamma Aries region, yet most of the other meteors, which were fainter, seemed to come from a diffuse region in the Aries-Triangulid area in general.
Also, in 1994 Bob Lunsford saw more meteors from the area near Gamma Arietis than Alpha Triangulii.
