A formation scenario of young stellar groups in the region of the Scorpio Centaurus OB association.

ORTEGA V.G., JILINSKI E., DE LA REZA R. and BAZZANELLA B.

Abstract (from CDS):

The main objective of this work is to investigate the role played by Lower Centaurus Crux (LCC) and Upper Centaurus Lupus (UCL), both subcomponents of the Scorpio Centaurus OB association (Sco-Cen), in the formation of the groups β Pictoris, TW Hydrae, and the η Chamaeleontis cluster. The dynamical evolution of all the stellar groups involved and of the bubbles and shells blown by LCC and UCL are calculated, and followed from the past to the present. This leads to a formation scenario in which (1) the groups β Pictoris, TW Hydrae were formed in the wake of the shells created by LCC and UCL, (2) the young cluster η Chamaeleontis was born as a consequence of the collision of the shells of LCC and UCL, and (3) the formation of Upper Scorpius (US), the other main subcomponent of the Sco-Cen association, may have been started by the same process that created η Chamaeleontis.
