The Axially Symmetric Ejecta of Supernova 1987A
L. Wang, J. C. Wheeler, P. Hoeflich +15
Extensive early observations proved that the ejecta of supernova 1987A (SN 1987A) are aspherical. Fifteen years after the supernova explosion, the Hubble Space Telescope has resolv…
Effect of anisotropy on universal transport in unconventional superconductors
W. C. Wu, D. Branch, J. P. Carbotte
We investigate the universal electronic transport for a mixed +s-wave superconductor in the presence of an anisotropic elliptical Fermi surface. Similar to the univers…
Low Luminosity Type II Supernovae: Spectroscopic and Photometric Evolution
A. Pastorello, L. Zampieri, M. Turatto +10
In this paper we present spectroscopic and photometric observations for four core collapse supernovae (SNe), namely SNe 1994N, 1999br, 1999eu and 2001dc. Together with SN 1997D, we…
On the High--Velocity Ejecta of the Type Ia Supernova 1994D
K. Hatano, D. Branch, A. Fisher +2
Synthetic spectra generated with the parameterized supernova synthetic-spectrum code SYNOW are compared to spectra of the Type Ia SN 1994D that were obtained before the time of max…
Direct Analysis of Spectra of the Peculiar Type Ia Supernova 2000cx
D. Branch, R. C. Thomas, E. Baron +6
The Type Ia SN 2000cx exhibited multiple peculiarities, including a lopsided B-band light-curve peak that does not conform to current methods for using shapes of light curves to st…
The Spectrum of the FeLoBAL Quasar FBQS 1214+2803: A Resonance-Scattering Interpretation
D. Branch, K. M. Leighly, R. C. Thomas +1
The usual interpetation of the spectrum of a BAL QSO is that a broad-band continuum from the central engine plus broad emission lines from a surrounding region (the BELR) emerges f…
