Photometric Observations of an SU UMa-type Dwarf Nova VW Coronae Borealis during Outbursts
D. Nogami, M. Uemura, R. Ishioka +2
We report the photometric observations of an SU UMa-type dwarf nova VW CrB during two superoutbursts in 2001 and 2003 and a normal outburst in 2003. Superhumps with a period of 0.0…
Possibility of color magnetic superconductivity
Toshitaka Tatsumi, Tomoyuki Maruyama, Eiji Nakano
Two aspects of quark matter at high density are addressed: one is color superconductivity and the other is ferromagnetism. We are mainly concerned with the latter and its relation…
Clustering in stable and unstable nuclei in -shell and -shell regions
Y. Kanada-En'yo, M. Kimura, H. Horiuchi
According to microscopic calculations with antisymmetrized molecular dynamics, we studied cluster features in stable and unstable nuclei. A variety of structure was found in stable…
Theta lifting of nilpotent orbits for symmetric pairs
Kyo Nishiyama, Hiroyuki Ochiai, Chen-bo Zhu
We consider a reductive dual pair (G, G') in the stable range with G' the smaller member and of Hermitian symmetric type. We study the theta lifting of nilpotent K'_C-orbits, where…
Ferromagnetism and Superconductivity in Quark Matter - Color magnetic superconductivity -
Toshitaka Tatsumi, Tomoyuki Maruyama, Eiji Nakano
A coexistent phase of spin polarization and color superconductivity in high-density QCD is studied at zero temperature. The axial-vector self-energy stemming from the Fock exchange…
Coronal Heating and Acceleration of the High/Low-Speed Solar Wind by Fast/Slow MHD Shock Trains
Takeru K. Suzuki
We investigate coronal heating and acceleration of the high- and low-speed solar wind in the open field region by dissipation of fast and slow magnetohydrodynamical (MHD) waves thr…
A Disk Galaxy of Old Stars at z ~ 2.5
Alan Stockton, Gabriela Canalizo, Toshinori Maihara
We describe observations of a galaxy in the field of the radio galaxy 4C 23.56, photometrically selected to have a spectral-energy distribution consistent with an old ste…
A self-consistent QRPA study of quadrupole collectivity around 32Mg
Masayuki Yamagami, Nguyen Van Giai
On the basis of the Hartree-Fock-Bogoliubov (HFB) plus quasiparticle random phase approximation method (QRPA) based on the Green's function approach with Skyrme force, we discuss t…
Demonstration of a solid deuterium source of ultra-cold neutrons
A. Saunders, J. M. Anaya, T. J. Bowles +26
Ultra-cold neutrons (UCN), neutrons with energies low enough to be confined by the Fermi potential in material bottles, are playing an increasing role in measurements of fundamenta…
Determination of polarized parton distribution functions and their uncertainties
M. Hirai, S. Kumano, N. Saito
We investigate the polarized parton distribution functions (PDFs) and their uncertainties by using the world data on the spin asymmetry A_1. The uncertainties of the polarized PDFs…
Negative-Parity Baryons in Quenched Anisotropic Lattice QCD
Y. Nemoto, N. Nakajima, H. Matsufuru +1
We study negative-parity baryon spectra in quenched anisotropic lattice QCD. The negative-parity baryons are measured as the parity partner of the ground-state baryons. In addition…
Angular Momentum Transport by MHD Turbulence in Accretion Disks: Gas Pressure Dependence of the Saturation Level of the Magnetorotational Instability
Takayoshi Sano, Shu-ichiro Inutsuka, Neal J. Turner +1
The saturation level of the magnetorotational instability (MRI) is investigated using three-dimensional MHD simulations. The shearing box approximation is adopted and the vertical…

Infrared (IR) absorption spectroscopy has been used to probe the evolution of microscopic vibrational states upon the temperature- and photo-induced spin crossovers in [Fe(2-picoly…
A Discovery of a Peculiar Pulsar in the Small Magellanic Cloud
Masaru Ueno, Hiroya Yamaguchi, Shin-ichiro Takagi +2
We report on a peculiar X-ray binary pulsar IKT1 = RXJ0047.3-7312 observed with XMM-Newton in Oct. 2000. The X-ray spectrum is described by a two-component spectrum. The hard compo…
Fully Gapped Single-Particle Excitations in the Lightly Doped Cuprates
K. M. Shen, T. Yoshida, D. H. Lu +23
The low-energy excitations of the lightly doped cuprates were studied by angle-resolved photoemission spectroscopy. A finite gap was measured over the entire Brillouin zone, includ…
Braneworld Kaluza-Klein Corrections in a Nutshell
Sugumi Kanno, Jiro Soda
Evaluating Kaluza-Klein (KK) corrections is indispensable to test the braneworld scenario. In this paper, we propose a novel symmetry approach to a 4-dimensional effective action w…
A General Formulation of the Source Confusion Statistics and Application to Infrared Galaxy Surveys
Tsutomu T. Takeuchi, Takako T. Ishii
Source confusion has been a long-standing problem in the astronomical history. In the previous formulation, sources are assumed to be distributed homogeneously on the sky. This fun…
