A 16-Year Photometric Campaign on the Eclipsing Novalike Variable DW Ursae Majoris
D. R. S. Boyd, E. de Miguel, J. Patterson +29
We present an analysis of photometric observations of the eclipsing novalike variable DW UMa made by the CBA consortium between 1999 and 2015. Analysis of 372 new and 260 previousl…
Curious Variables Experiment (CURVE). CCD Photometry of V419 Lyr in its 2006 July Superoutburst
A. Rutkowski, A. Olech, K. Mularczyk +3
We report extensive photometry of the dwarf nova V419 Lyr throughout its 2006 July superoutburst till quiescence. The superoutburst with amplitude of ~3.5 magnitude lasted at least…
HT Cas - eclipsing dwarf nova during its superoutburst in 2010
K. Bakowska, A. Olech, A. Rutkowski +3
We present results of a world-wide observing campaign of the eclipsing dwarf nova - HT Cas during its superoutburst in November 2010. Using collected data we were able to conduct a…
Discovery of a Very Bright, Nearby Gravitational Microlensing Event
B. Scott Gaudi, Joseph Patterson, David S. Spiegel +18
We report the serendipitous detection of a very bright, very nearby microlensing event. In late October 2006, an otherwise unremarkable A0 star at a distance ~1 kpc (GSC 3656-1328)…
IX Draconis - a curious ER UMa-type dwarf nova
M. Otulakowska-Hypka, A. Olech, E. de Miguel +3
We report results of an extensive world-wide observing campaign devoted to a very active dwarf nova star - IX Draconis. We investigated photometric behaviour of the system to deriv…
MN Draconis - peculiar, active dwarf nova in the period gap
K. Bakowska, A. Olech, R. Pospieszynski +7
Context: We present results of an extensive world-wide observing campaign of MN Draconis. Aims: MN Draconis is a poorly known active dwarf nova in the period gap and is one of the…
Accretion-disc precession in UX Ursae Majoris
E. de Miguel, J. Patterson, D. Cejudo +25
We report the results of a long campaign of time-series photometry on the nova-like variable UX Ursae Majoris during 2015. It spanned 150 nights, with ~1800 hours of coverage on 12…
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…
Polarimetry and the Long Awaited Superoutburst of BZ UMa
A. Price, J. Masiero, A. A. Henden +18
BZ UMa is a cataclysmic variable star whose specific classification has eluded researchers since its discovery in 1968. It has outburst and spectral properties consistent with both…
