The Bernstein Conjecture, Minimal Cones, and Critical Dimensions
Gary W. Gibbons, Kei-ichi Maeda, Umpei Miyamoto
Minimal surfaces and domain walls play important roles in various contexts of spacetime physics as well as material science. In this paper, we first review the Bernstein conjecture…
First Stars -- Type Ib Supernovae Connection
Keni'chi Nomoto, Masaomi Tanaka, Yasuomi Kamiya +2
The very peculiar abundance patterns observed in extremely metal-poor (EMP) stars can not be explained by ordinary supernova nucleosynthesis but can be well-reproduced by nucleosyn…
Dynamics of intersecting brane systems -- Classification and their applications --
Kei-ichi Maeda, Nobuyoshi Ohta, Kunihito Uzawa
We present dynamical intersecting brane solutions in higher-dimensional gravitational theory coupled to dilaton and several forms. Assuming the forms of metric, form fields, and di…
Measurement of the Kerr Spin Parameter by Observation of a Compact Object's Shadow
Kenta Hioki, Kei-ichi Maeda
A black hole casts a shadow as an optical appearance because of its strong gravitational field. We study how to determine the spin parameter and the inclination angle by observing…
Dust in Supernovae; Formation and Evolution
Takashi Kozasa, Takaya Nozawa, Nozomu Tominaga +3
Core--collapsed supernovae (CCSNe) have been considered to be one of sources of dust in the universe. What kind and how much mass of dust are formed in the ejecta and are injected…
Attractor Universe in the Scalar-Tensor Theory of Gravitation
Kei-ichi Maeda, Yasunori Fujii
In the scalar-tensor theory of gravitation it seems nontrivial to establish if solutions of the cosmological equations in the presence of a cosmological constant behave as attracto…
