Discovery of a New Deeply Eclipsing SU UMa-Type Dwarf Nova, IY UMa (= TmzV85)
M. Uemura, T. Kato, K. Matsumoto +15
We discovered a new deeply eclipsing SU UMa-type dwarf nova, IY UMa, which experienced a superoutburst in 2000 January. Our monitoring revealed two distinct outbursts, which sugges…
The 2001 Superoutburst of WZ Sagittae
J. Patterson, G. Masi, M. Richmond +25
We report the results of a worldwide campaign to observe WZ Sagittae during its 2001 superoutburst. After a 23-year slumber at V=15.5, the star rose within 2 days to a peak brightn…
A Newly Discovered SU UMa-Type Dwarf Nova, HS 1449+6415
D. Nogami, D. Engels, B. T. Gaensicke +3
We report time-resolved photometric observations of the Hamburg Quasar Survey-selected dwarf nova HS 1449+6415 (= RX J1450.5+6403) during the interval from JD 2451672 to 2451724. D…
The Pauli equation with complex boundary conditions
D. Kochan, D. Krejcirik, R. Novak +1
We consider one-dimensional Pauli Hamiltonians in a bounded interval with possibly non-self-adjoint Robin-type boundary conditions. We study the influence of the spin-magnetic inte…
SDSS J162520.29+120308.7 - a new SU UMa star in the period gap
A. Olech, E. de Miguel, M. Otulakowska +13
We report results of an extensive world-wide observing campaign devoted to the recently discovered dwarf nova SDSS J162520.29+120308.7 (SDSS J1625). The data were obtained during t…
Superhumps in Cataclysmic Binaries. XXIV. Twenty More Dwarf Novae
J. Patterson, J. Thorstensen, J. Kemp +23
We report precise measures of the orbital and superhump period in twenty more dwarf novae. For ten stars, we report new and confirmed spectroscopic periods - signifying the orbital…
A New SU UMa-Type Dwarf Nova, QW Serpentis (= TmzV46)
D. Nogami, M. Uemura, R. Ishioka +11
We report on the results of the QW Ser campaign which has been continued from 2000 to 2003 by the VSNET collaboration team. Four long outbursts and many short ones were caught duri…
Kilo-Second Quasi-Periodic Oscillations in the Cataclysmic Variable DW Cancri
M. Uemura, T. Kato, R. Ishioka +2
Our photometric monitoring revealed that DW Cnc, which was originally classified as a dwarf nova (V=15--17.5), remained at a bright state of Rc=14.68+/-0.07 for 61 days. In conjunc…
