3. Hvad vi skal snakke om i aften
Om
spektroskopiens historie
Hvordan virker det?
Hvad kan man bruge det til?
PAUSE
Lidt mere om planeter og seismologi
Hvordan bygger man en spektrograf?
Lidt til filosofien, og hvad vi bl.a. har lært

17. Om astronomi
“Of all objects, the planets are those which
appear to us under the least varied aspect. We
see how we may determine their forms, their
distances, their bulk, and their motions, but we
can never known anything of their chemical or
mineralogical structure; and, much less, that of
organized beings living on their surface ...”
Auguste Comte, The Positive Philosophy(1842)
18. Om astronomi
“We can never learn their [Heavenly bodies']
internal constitution, nor, in regard to some of
them, how heat is absorbed by their
atmosphere. We may therefore define
Astronomy as the science by which we discover
the laws of the geometrical and mechanical
phenomena presented by the heavenly bodies.”
Auguste Comte, Book II: Astronomy (1853)
86. Formål
To study the internal structure and evolution
of stars at a level of detail similar to that
achieved for the Sun under similar observing
conditions, using asteroseismology (and look
at the Sun during the day)
To search for and characterize planets with
masses comparable to the Earth in orbit
around other stars.
