Magnetic Energy and Helicity Budgets in the Active-Region Solar Corona. I. Linear Force-Free Approximation

Autor: Georgoulis, M. K., LaBonte, Barry J.

We self-consistently derive the magnetic energy and relative magnetic helicity budgets of a three-dimensional linear force-free magnetic structure rooted in a lower boundary plane. For the potential magnetic energy we derive a general expression that

Report

Reconstruction of an Inductive Velocity Field Vector from Doppler Motions and a Pair of Solar Vector Magnetograms

Autor: Georgoulis, Manolis K., LaBonte, Barry J.

Publikováno v: Astrophys.J.636:475-495,2005

We outline a general methodology to infer the inductive velocity field vector in solar active regions. For the first time, both the field-aligned and the cross-field velocity components are reconstructed. The cross-field velocity solution accounts fo

The Nature of Solar Polar Rays

Autor: Li, Jing, Jewitt, David, LaBonte, Barry

We use time series observations from the SOHO and Yohkoh spacecraft to study solar polar rays. Contrary to our expectations, we find that the rays are associated with active regions on the sun and are not features of the polar coronal holes. They are

Studies of Chromospheric Activity Observed in Hα and D₃

Autor: LaBonte, Barry James

Several studies of chromospheric activity as observed in Hα and D3 have been made. These are: Hα Observations of the August 12, 1975 Type III-RS Bursts (Solar Physics, 50, 201, 1976); A Measurement of the Helium D3 Profile with a Birefringent Filte
