Supersymmetric Intersecting Branes in Time-dependent Backgrounds
Nobuyoshi Ohta, Kamal L. Panigrahi
We construct a family of supersymmetric solutions in time-dependent backgrounds in supergravity theories. One class of the solutions are intersecting brane solutions and another cl…
Fermions on Colliding Branes
Gary Gibbons, Kei-ichi Maeda, Yu-ichi Takamizu
We study the behaviour of five-dimensional fermions localized on branes, which we describe by domain walls, when two parallel branes collide in a five-dimensional Minkowski backgro…
Chemical Abundances in the Secondary Star of the Black Hole Binary V4641 Sagittarii (SAX J1819.3-2525)
Kozo Sadakane, Akira Arai, Wako Aoki +10
We report on detailed spectroscopic studies performed for the secondary star in the black hole binary (micro-quasar) V4641 Sgr in order to examine its surface chemical composition…
Supersymmetric Rotating Black Hole in a Compactified Spacetime
Kei-ichi Maeda, Nobuyoshi Ohta, Makoto Tanabe
We construct a supersymmetric rotating black hole with asymptotically flat four-dimensional spacetime times a circle, by superposing an infinite number of BMPV black hole solutions…
Nucleosynthesis Yields of Core-Collapse Supernovae and Hypernovae, and Galactic Chemical Evolution
Ken'ichi Nomoto, Nozomu Tominaga, Hideyuki Umeda +2
We present new nucleosynthesis yields as functions of the stellar mass, metallicity, and explosion energy (corresponding to normal supernovae and Hypernovae). We apply the results…
Models for the Type Ic Hypernova SN 2003lw associated with GRB 031203
Paolo A. Mazzali, Jinsong Deng, Elena Pian +10
The Gamma-Ray Burst 031203 at a redshift z=0.1055 revealed a highly reddened Type Ic Supernova, SN 2003lw, in its afterglow light. This is the third well established case of a link…
