ASTR 5610 (Majewski) Lecture Notes


Intermediate Population II, Thick Disk

Age from:


SUMMARY

General consensus is that IPII is old -- approximately the age of the halo.

Precise timing bears critically on formation scenarios, but is still somewhat uncertain.

Seems that IPII began forming soon after halo began forming but before the halo stopped making globulars.
