Flare rates and the McIntosh active-region classifications
Autor: P. L. Bornmann, Donald L. Shaw
Publikováno v: Solar Physics. 150:127-146
Multiple linear regression analysis was used to derive the effective solar flare contributions of each of the McIntosh classification parameters. The best fits to the combined average number of M- and X-class X-ray flares per day were found when the

Solar X‐Ray Physics
Autor: P. L. Bornmann
Publikováno v: Reviews of Geophysics. 29:915-924
Research on solar X-ray phenomena performed by American scientists during 1987-1990 is reviewed. Major topics discussed include solar images observed during quiescent times, the processes observed during solar flares, and the coronal, interplanetary,

Fluid flow in a jet and the CA XIX line profiles observed during solar flares
Autor: P. L. Bornmann, J. R. Lemen
Publikováno v: Lecture Notes in Physics ISBN: 9783540552468
The present study considers two types of fluid models as methods for reproducing the blueshifts and line broadening observed in soft X-ray lines during the rise of solar flares. The fluid models representing the laminar flow of material in a jet and

Chromospheric Evaporation Theory
Autor: P. L. Bornmann
Publikováno v: The Many Faces of the Sun ISBN: 9781461271451
Chromospheric evaporation is currently the most popular theory for explaining the source of the coronal flare material and the upward motions of X-ray emitting material observed as soft X-ray line broadenings and line shifts at the start of solar fla

Interrelation of soft and hard X-ray emissions during solar flares. II - Simulation model
Autor: R. M. Winglee, P. L. Bornmann, George A. Dulk, John C. Brown
Publikováno v: The Astrophysical Journal. 375:382
Two-dimensional electrostatic particle simulations are presented which incorporate the effect of quasi-static electric fields on particle dynamics as well as effects associated with wave-particle interactions induced by the accelerated particles. The

Limits to derived flare properties using estimates for the background fluxes - Examples from GOES
Autor: P. L. Bornmann
Publikováno v: The Astrophysical Journal. 356:733
A method has been presented for restricting the random derived flare temperatures and emission measures. The method is based on three tests and is applicable not only to disk-integrated observations, but also for any high-resolution observations that
