•At these T’s, r’s, hydrogen will be a gas
–At high enough T, as pressure (P) increases
and r
increases,
you never really get a “liquid”, just a dense gas.
•H ionization?
–On outside, H mostly neutral (a small fraction is ionized)
•remember H ionized and Balmer lines gone
only above 10,000 K
–Over most of interior, H completely
ionized
•separate electrons (e-) and protons
(p+)
•Ionized gas called a
“plasma”
•
•No discrete “surface” –
just increasing r, T, P, and “opacity”
