Erratum: Variational Principles for Stellar Structure
Abstract
In the paper ``HST and MERLIN Observations of 3C 264A Laboratory for Jet Physics and Unified Schemes'' by Stefi A. Baum, Christopher P. O'Dea, Gabriele Giovannini, John Biretta, William B. Cotton, Sigrid de Koff, Luigina Feretti, Daniel Golombek, Lucas Lara, Ferdinando D. Macchetto, G. K. Miley, William B. Sparks, Tiziana Venturi, and Serguei S. Komissarov (ApJ, 483, 178 [1997]), there are errors in some of the exponents in equations (18), (20), and (21). The correct equations were used in the analysis, and the results of the paper are not affected. Section 5.4 including equations (18)(21) with the correct exponents is presented here.
5.4. Brightness Variations
Combining the results of previous sections, we obtain the following equations for the proper emissivity and the observed brightness variations (intensity per unit area I_{ν} = ɛ_{ν} r_{j}) along a steady relativistic jet:
Predominantly parallel field (case of 3C 264): ɛ∼_{ν}~(Γ_{j}v_{j})^{(γ+2)/3}r^{(5γ+7)/3}_{j} ,I_{ν}~(Γ_{j}v_{j})^{(γ+2)/3}r^{(5γ+4)/3}_{j}D^{2+α} . (18) (19)
Predominantly transverse field: ɛ∼_{ν}~(Γ_{j}v_{j})^{(5γ+7)/6}r^{(7γ+11)/6}_{j} ,I_{ν}~(Γ_{j}v_{j})^{(5γ+7)/6}r^{(7γ+5)/6}_{j}D^{2+α} . (20) (21)
