Observations of the Ca II K line, made within a few months of eclipse, are reviewed for the systems ζ Aurigae, 32 Cygni and 31 Cygni. The intensities of these lines at a given phase differ from one eclipse to another, and at ingress and at egress for the same by: The orbits and dimensions of the eclipsing binary system 31 Cygni / [by] K.O.

Abstract: We have measured the profiles of the Ca II H and K chromospheric emission lines in main sequence stars of spectral type M5-K7 ( solar masses) using multiple high resolution spectra obtained during six years with the HIRES spectrometer on the Keck 1 telescope.

A set of medium to high-resolution observations of H-alpha and Ca II K lines in a sample of Population I stars is presented in order to examine the systematics of H-alpha absorption profiles and. the four observations independently. Also the Iron line parameters match the values obtained before.
The χ2 red yields a value of with dof. As shown in Fig. 2 a deviation between the data points and this pure thermal model is still present in the time averaged spectrum.
Therefore we added a non-thermal component in theFile Size: KB. The ejection velocities (V ej) were measured from the P Cygni profiles. The measured lines include Hα, Hβ, and Hγ, which have measurable P Cygni profiles from April 16 to June 1 (t = – days); Fe ii recombination lines at, and Å; O i Å; and the Ca ii K line at Å.
Using photoelectric observations in the Fe line we obtained line-of-sight velocities at nine different positions on the solar disk, as functions of one horizontal co-ordinate and time.

Estimate the observed wavelength for the nm line in the Balmer series of hydrogen in the spectrum of a galaxy whose distance from us is (a) 10 6 ly, (b) 10 8 ly, (c) 10 10 ly.
The first thing to do is turn the LY into Mpc. Since 1 pc is LY, then 10 6 Ly Mpc 10 8 Ly = Mpc and finally 10 10 Ly = Mpc. The “K line” of Ca II lies at nm (rest wavelength).
A star is observed with a spectrograph, and the same line is observed at nm in the spectrum of the star. Constant: c = x km/s. Calculate the radial velocity of the star.

Mount Wilson observations of the S indices of selected non-cycling stars suggested their Ca ii H & K emission lay well below that of the contemporary solar minimum (Baliunas and Jastrow, ), from which White et al.
deduced that the K emission from the Sun during the Maunder Minimum may have been as little as 11% that of current cycle by: The Nature of Solar Prominences Einar Tandberg-Hanssen (auth.) and Kluwer Academic Publishers wanted to pub lish such a book.
I, therefore, venture to present this monograph in the hope of kindling the interest of some graduate students in the study of this-probably the most spectacular and often the most beautiful of solar activity.

Spectral line formation theory is at the heart of astrophysical diagnostic. Our knowledge of abundances, in both stellar and interstellar contexts, comes almost enti rely from line analysis, as does a major fraction of our ability to model stellar atmospheres.
