Kavli Affiliate: P. C. Joss| First 5 Authors: A. Majczyna, A. Majczyna, , , | Summary:This paper presents the set of plane-parallel model atmosphere equations for a very hot neutron star (X-ray burst source). The model equations assume both hydrostatic and radiative equilibrium, and the equation of state of an ideal gas in local thermodynamic […]
Kavli Affiliate: P. C. Joss| First 5 Authors: J. Madej, J. Madej, , , | Summary:We explore photometric properties of hypothetical iron core white dwarfs and compute their expected colors in UBVRI Johnson broadband system. Atmospheres of iron core WDs in this paper consist of pure iron covered by a pure hydrogen layer of an […]
Kavli Affiliate: Steffen Luitz| First 5 Authors: S. Luitz, S. Luitz, , , | Summary:The BaBar experiment is the particle detector at the PEP-II B-factory facility at the Stanford Linear Accelerator Center. During the summer shutdown 2002 the BaBar Event Building and Level-3 trigger farm were upgraded from 60 Sun Ultra-5 machines and 100MBit/s Ethernet […]
Kavli Affiliate: P. C. Joss| First 5 Authors: A. Majczyna, A. Majczyna, , , | Summary:We present model atmospheres and theoretical spectra for X-ray bursters. Our models include the effects of Compton scattering on free electrons. The atmospheres have compositions that are mixtures of hydrogen, helium, and iron. For our models the ratio of color […]
Kavli Affiliate: Edmund Bertschinger| First 5 Authors: Lutz Wisotzki, Lutz Wisotzki, , , | Summary:We report the discovery of a new gravitationally lensed QSO, at a redshift z = 1.689, with four QSO components in a cross-shaped arrangement around a bright galaxy. The maximum separation between images is 2.6 arcsec, enabling a reliable decomposition of […]
Kavli Affiliate: Yukari Ito| First 5 Authors: Yukari Ito, Yukari Ito, , , | Summary:There are many generalizations of the McKay correspondence for higher dimensional Gorenstein quotient singularities and there are some applications to compute the topological invariants today. But some of the invariants are completely different from the classical invariants, in particular for non-Gorenstein […]
