WZ Sge-type dwarf novae [PDF]

open access: yesPublications of the Astronomical Society of Japan, 2015
AbstractWe have summarized the current understanding and recently obtained findings about WZ Sge-type dwarf novae. We also reviewed the historical development of the understanding of these objects, provided the modern criteria, and reviewed the past research in relation to superhumps, early superhumps, and the outburst mechanism. We regard the presence

Inner Disk Structure of Dwarf Novae in the Light of X-Ray Observations [PDF]

open access: yesActa Polytechnica CTU Proceedings, 2015
Diversity of the X-ray observations of dwarf nova are still not fully understood. I review the X-ray spectral characteristics of dwarf novae during the quiescence in general explained by cooling flow models and the outburst spectra that show hard X-ray ...

Outbursts of dwarf novae [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 1984
A review is given of the observational facts related to the outbursts of dwarf novae and of relevant aspects of the theory of accretion disks. It now appears possible to explain the outbursts of dwarf novae in terms of a nonstationary accretion behavior. Between the outbursts, the material supplied by the secondary component is stored in the relatively

A systematic X-ray study of the dwarf novae observed with Suzaku [PDF]

open access: bronze, 2016
X-ray behavior of the dwarf novae (DNe) outside the quiescent state has not been fully understood. We thus assembled 21 data sets of the 15 DNe observed by the Suzaku satellite by the end of 2013, which include spectra taken during not only the ...

Statistical analysis of properties of dwarf novae outbursts [PDF]

open access: bronze, 2016
We present a statistical study of all measurable photometric features of a large sample of dwarf novae during their outbursts and superoutbursts. We used all accessible photometric data for all our objects to make the study as complete and up-to-date as ...

Distances and Absolute Magnitudes of Dwarf Novae: Murmurs of Period Bounce [PDF]

open access: green, 2009
We redetermine the relationship between absolute magnitude and orbital period for dwarf novae, based on 46 stars with good distance estimates. This improves upon Warner's previous relation, building upon today's improved estimates of distance and binary ...

An Empirical Correlation of Tmax–MWD of Dwarf Novae and the Average White Dwarf Mass in Cataclysmic Variables in the Galactic Bulge [PDF]

open access: bronze, 2018
The mean white dwarf (WD) mass in the Galactic bulge cataclysmic variables (CVs) was measured by applying the shock temperature-WD mass correlation of magnetic cataclysmic variables (mCVs) to the Galactic bulge X-ray emission (GBXE) spectra. However, the

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

open access: yesAstrophysical 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.

Three Z Camelopardalis-type dwarf novae exhibiting IW Andromedae-type phenomenon [PDF]

open access: greenNippon Tenmon Gakkai obun kenkyu hokoku, 2018
I found that V507 Cyg, IM Eri and FY Vul are Z Cam-type dwarf novae and they showed sequences of standstill terminated by brightening, in contrast to fading in ordinary Z Cam stars, followed by damping oscillation.

Very high-energyγ-ray observations of novae and dwarf novae with the MAGIC telescopes [PDF]

open access: bronzeAstronomy & Astrophysics, 2015
Context. In the last five years the Fermi Large Area Telescope (LAT) instrument detected GeV-ray emission from five novae. The GeV emission can be interpreted in terms of an inverse Compton process of electrons accelerated in a shock.
