Variation of the Hβ Emission Lines of YY Geminorum

Publications of the Astronomical Society of Japan, 1980
Abstract Forty-four image-tube spectra of YY Gem (4 Å mm−1, λλ 4820–4900 Å) are analyzed to yield the radial velocity curves and the variations in the intensity and the width of Hβ emission lines during the quiescent phase at epoch 1978 January 4–8. The present study disagrees with the claim by Leung and Schneider (1978) that the orbital

Observation of enhanced emission of the O VIII Hα line in a recombining laser-produced plasma

Applied Physics Letters, 1984
We have observed enhanced emission of the O VIII Hα line at 121 eV from a recombining plasma produced by laser heating of a thin Formvar foil with two opposed cylindrically focused (0.3×1.4 cm) 5-TW laser beams. The time-dependent intensity of the Hα line increases by nearly an order of magnitude as the plasma length is increased from 0.27 to 1.27 cm ...

Variation of the Hβ Emission Lines of YY Geminorum. II. Change of Sectorial Structures of Active Regions

Publications of the Astronomical Society of Japan, 1982
Abstract Sixty-three image-tube spectrograms of YY Gem (4 Å mm−1, λλ4820–4900 Å) are analyzed to yield the radial-velocity curves and the variations in the intensities and the widths of Hβ emission lines during the quiescent phase at epochs 1980 February 11–16, 1981 January 14–15, and 1981 March 11.
