Spectrum Analysis of the Type Ib Supernova 1999dn: Probable Identifications of C II and H-alpha
J. S. Deng, Y. L. Qiu, J. Y. Hu +2
Low resolution spectra of SN 1999dn at early times are presented and compared with synthetic spectra generated with the parameterized supernova synthetic-spectrum code SYNOW. We fi…
Spectral Models of the Type Ic SN 1994I in M51
E. Baron, David Branch, Peter H. Hauschildt +2
We present detailed non-local thermodynamic equilibrium (NLTE) synthetic spectra for comparison with a time series of observed optical spectra of the Type Ic supernova 1994I which…
The Effects of Inhomogeneities on Evaluating the Deceleration Parameter q
R. Kantowski, T. Vaughan, D. Branch
Analytic expressions for distance-redshift relations which have been corrected for the effects of some inhomogeneities in the Friedmann-Robertson-Walker (FRW) mass density are used…
Preliminary Spectral Analysis of SN 1994I
E. Baron, P. H. Hauschildt, D. Branch +2
We present optical spectra of the Type Ic supernova 1994I in M51 and preliminary non-LTE analysis of the spectra. Our models are not inconsistent with the explosions of C+O cores o…
