Virialization in N-Body Models of the Expanding Universe: 1. Isolated Pairs
(Univ Chicago Press, 1985)
Manganese and carbon lines as temperature indicators
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1986-03)
Selected hyperfine structure broadened lines of various excitations and the carbon line at 5380 Å are tested as temperature diagnostics for photospheric heterogeneities. This is done by comparing the observed center-to-limb ...
On the completeness of the analysis of third and fourth spectra of the iron group, and the spectra of early B stars
(Elsevier, 1988-04-02)
The spectroscopic analysis of normal, early B stars requires a sound atomic data base, especially for the third and fourth spectra of the iron-group elements. We review the present status of the term analyses of third and ...
On the Sun's limb brightening in the visible
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1984-06)
It is shown that in practice the method by Julius (1906) is incapable to determine the limb intensity drop. The brief intensity reversal near the extreme limb as derived from cinematography of flash spectra can be explained ...

Large-Scale Clustering of Galaxies With Massive Dark Halos: 2. Mass-to-Light Profiles and Dynamic Mass Estimates of Galaxy Groups

Characterististics of plage fragments with photospheric network properties
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1980-08)
Using data taken with the multi-channel magnetograph at KPNO, we demonstrate that plage regions surrounding a sunspot have thermal properties found in the photospheric network. These network-like regions existed up to the ...
