Using Cepheids to determine the galactic abundance gradient I. The solar neighbourhood [PDF]

, 2001
A number of studies of abundance gradients in the galactic disk have been performed in recent years. The results obtained are rather disparate: from no detectable gradient to a rather significant slope of about -0.1 dex kpc -1. The present study concerns

Letter to the Editor
UHF electromagnetic emission stimulated by HF pumping of the ionosphere [PDF]

Annales Geophysicae, 2002
UHF electromagnetic emission (with a frequency near 600 MHz) from the F-region of the ionosphere pumped by an HF powerful radio wave is revealed. Possible mechanisms of the emission excitation, such as plasma mode con-version, scattering or Earth ...
