Structure of the Solar Dust Corona and its Interaction with the other Coronal Components
Y. Y. Shopov, D. A. Stoykova, K. Stoitchkova +9
We developed a new technique for registration of the far solar corona from ground-based observations at distances comparable to those obtained from space coronagraphs. It makes pos…
Luminescence of Speleothems in Italian Gypsum Caves: Preliminary Report
Yavor Y. Shopov, Diana Stoykova, Paolo Forti
The luminescence of 3 speleothem samples from the Acquafredda karst system and 1 from the Novella Cave (Gessi Bolognesi Natural Park, Italy) has been recorded using excitation by i…
Noah's Flood and the Associated Tremendous Rainfall as a Possible Result of Collision of a Big Asteroid with the Sun
Y. Y. Shopov, L. T. Tsankov, L. N. Georgiev +4
A good correlation between the growth rate of the cave speleothems and the annual precipitation at the cave site allow quantitative reconstruction of the precipitation. Measuring t…
Past Annual Variations of the Karst Denudation Rates
Y. Shopov, D. Stoykova, L. T. Tsankov +8
We used the quantitative theory of solubility of karst rocks of Shopov et. al, (1989, 1991a) in dependence of the temperature and other thermodynamic parameters to make reconstruct…
Influence of the Solar Luminosity on the Glaciations, Earthquakes and Sea Level Changes
Yavor Y. Shopov, Diana A. Stoykova, Katerina Stoitchkova +1
Glaciations were attributed to variations of the Earths orbit (Milankovitch cycles). But the best ever dated paleoclimatic record (from a speleothem from Devils Hole, Nevada) demon…
Activators of Luminescence in Speleothems as Source of Major Mistakes in Interpretation of Luminescent Paleoclimatic Records
Y. Y. Shopov
This work summarizes the main results of the operation of the International Program Luminescence of Cave Minerals of the commission on Physical Chemistry and Hydrogeology of Karst…
