| • | D: Crucial. Strong dependence on |
||||||||||
| baryon
density. Measured from |
|||||||||||
| interstellar
absorption in UV/Far-UV with |
|||||||||||
| HST and
FUSE. Older values are [D/H] = |
|||||||||||
| 1.5 +/- 0.2 x
10-5, but we will have an |
|||||||||||
| update based
on FUSE results on high- |
|||||||||||
| order Lyman
lines by a volunteer. Keep |
|||||||||||
| in mind that
stars destroy D, so these |
|||||||||||
| numbers are lower
limits. Can also look |
|||||||||||
| in the IGM
using high-z quasars. |
