The Shape of Long Outbursts in U Gem Type Dwarf Novae from AAVSO Data [PDF]

, 2012
We search the American Association of Variable Star Observers (AAVSO) archives of the two best studied dwarf novae in an attempt to find light curves for long outbursts that are extremely well-characterized. The systems are U Gem and SS Cyg.

Characterization of Dwarf Novae Using SDSS Colors [PDF]

, 2012
We have developed a method for estimating the orbital periods of dwarf novae from the Sloan Digital Sky Survey (SDSS) colors in quiescence using an artificial neural network.

Comprehensive Listing of 208 Nova White Dwarf Masses as the Primary Determinant of Spectral Class and Light-curve Class

The Astrophysical Journal
For Galactic novae, I calculate and collect a comprehensive catalog of 208 measures of white dwarf (WD) masses ( M _WD ) and 232 measures of average V magnitudes in quiescence ( V _q ). These are collected into a comprehensive catalog of most fundamental

Dwarf Novae in the Shortest Orbital Period Regime: II. WZ Sge Stars as the Missing Population near the Period Minimum [PDF]

, 2010
WZ Sge-type dwarf novae are characterized by long recurrence times of outbursts (~10 yr) and short orbital periods (

Classical Novae Masquerading as Dwarf Novae? Outburst Properties of Cataclysmic Variables with ASAS-SN [PDF]

Astrophysical Journal, 2021
The unprecedented sky coverage and observing cadence of the All-Sky Automated Survey for SuperNovae (ASAS-SN) has resulted in the discovery and continued monitoring of a large sample of Galactic transients.

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits. [PDF]

Ecol Evol
This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

Thermal-viscous instability in tilted accretion disks: A possible application to IW Andromeda-type dwarf novae [PDF]

Nippon Tenmon Gakkai obun kenkyu hokoku, 2019

Turbulent and wind-driven accretion in dwarf novae threaded by a large-scale magnetic field [PDF]

Astronomy & Astrophysics, 2018
Dwarf novae (DNe) are accreting white dwarfs that show eruptions caused by a thermal-viscous instability in the accretion disk. The outburst timescales constrain α, the ratio of the viscous stress to the thermal pressure, which phenomenologically ...
