Spectral Theory of Dynamical Systems
A finite or a cr-finite measure n, or the measure class of such a measure is called
the spectral type of E if there exists an x £ H such that nx : nx(B) = (E(B)x, x), B £ B
has the same null sets as n. A finite or a cr-finite measure /z, or the measure ...

Stellar
Spectral Classification
This is done partly so that the change in the shape and slope of the continuum
can be seen as a function of spectral type and partly because consistency in
delineating the continuum, and so producing the rectification, is hard to achieve
for ...

Sky Catalogue 2000.0: Stars to magnitude 8.0
Each spectral type is divided into 10 subtypes, indicated by an appended number
from 0 to 9 (for example, AS). Occasionally, the subtypes have decimal
extensions, such as 60.5. The change in surface temperature corresponding to
adjacent ...

Spectral Classification and Multicolour Photometry
The observing list includes the several brightest single stars of each spectral type
, with emphasis on the latest types. The 8-color photometry will provide color
temperatures and 7(104) magnitudes in the infrared continuum, as well as
spectral ...

The maximal spectral type of the restriction of a representation to any closed
invariant subspace is absolutely continuous with respect to the maximal spectral
type of the representation. 1.4.2. Correlation coefi'icients. Similarly to the case of

not the absolute magnitudes. If we know the absolute magnitude for one spectral
type, then we can find the distance modulus for stars of that spectral type in the
cluster. The distance modulus is the same for all the stars in the cluster, so we
can ...

Horizons: Exploring the Universe
If a main-sequence star has a luminosity of 400 L}, what is its spectral type? (Hint:
See Figure 8-10 or 8-11.) 7. If a star has an apparent magnitude equal to its
absolute magnitude, how far away is it in parsecs? In light-years? 8. An O8 V star

Asymptotic Giant Branch Stars
A practical definition of a PAGB star using the central star properties is by means
of spectral type and luminosity class, see, e.g., [125]. The location of PAGBs in
the HR diagram as derived from evolutionary calculations suggests spectral
types ...
