Die sogenannten Trapez Sterne (wegen der Anordnung).<\/p>\n<p>Sie laufen unter dem Namen Theta1 Orionis = \u03b81 Ori<br \/>\nTheta2 ist der Erste der hellen 3 Sterne links hinter der Schockfront.<\/p>\n<p>Zum Trapez: Von den 4 Sternen Theta1 C \/ A \/ B \/ E ist optisch schon leicht erkennbar C am hellsten. Mit 40 Sonnenmassen ist er ein sehr massereicher Stern und mit 50.000 Grad sehr hei\u00df. Sogar der hei\u00dfeste Stern, den wir mit freiem Auge sehen k\u00f6nnen. Er leuchtet 200.000 fach heller als unsere Sonne. Seine gro\u00dfteils harte UV-Strahlung regt das Gas des Orion zum Leuchten an. Ohne ihn w\u00fcrde wir hier kaum etwas sehen.<br \/>\nDas rote Licht ist wie immer der Wasserstoff, Sauerstoff in Blau ist kaum vorhanden, sondern kommt vom reflektiertem Sternenlicht (Reflexionsnebel).<\/p>\n<p>Die Sterne des Trapez sind vor 1 &#8211; 2,5 Mio. Jahren aus der Gaswolke entstanden und f\u00fcllen hier in etwa einen Raum von der Gr\u00f6\u00dfe unseres Sonnensystems. Es sind nicht nur 4 Sterne, sondern sehr komplizierte Mehrfachsternsysteme. Selbst auf diesem 13 Sekunden Bild sind 2 weitere (E &amp; F) zu erkennen.<\/p>\n<p>Der Strahlungsdruck hat regelrecht eine H\u00f6hle in den Nebel frei geblasen. Man sieht die Schockfront (S) links. Dabei wurde weiteres Gas destabilisiert was zu gr\u00f6\u00dferen dichteren Massenansammlungen f\u00fchrt. Die Vorstufen sind sogenannte Protoplanetare Scheiben (P) die man hier zahlreich sieht.
