For Good Measure SS Cygni is a well-studied binary star system in the northern constellation Cygnus, consisting of a white dwarf that accretes matter from its companion star. Miller-Jones et al. (p. 950; see the Perspective by Schreiber) used radio observations to derive a model-independent distance to this prototypical accreting white dwarf system. The measurement places the system significantly closer than previously determined, reconciling the observed properties of SS Cygni with our current… 
One Good Measure
Radio observations show that the HST distance measure is wrong and that instead SS Cygni is exactly as far away as it should be according to the understanding of accretion disks.
Dwarf nova outbursts in intermediate polars
The disc instability model (DIM) has been very successful in explaining the dwarf nova outbursts observed in cataclysmic variables. When, as in intermediate polars (IP), the accreting white dwarf is
Hystereses in dwarf nova outbursts and low-mass X-ray binaries
Context. The disc instability model (DIM) successfully explains why many accreting compact binary systems exhibit outbursts, during which their luminosity increases by orders of magnitude. The DIM
Fourier time lags in the dwarf nova SS Cygni
To understand the physical processes governing accretion discs we can study active galactic nuclei (AGN), X-ray binary systems (XRBs) and cataclysmic variables (CVs). It has been shown that XRBs and
X-Ray Emissions from Accreting White Dwarfs: A Review
Interacting binaries in which a white dwarf accretes material from a companion - cataclysmic variables (CVs) in which the mass donor is a Roche-lobe filling star on or near the main sequence, and
On the Hubble Space Telescope Trigonometric Parallax of the Dwarf Nova SS Cygni
SS Cygni is one of the brightest dwarf novae (DNe), and one of the best-studied prototypes of the cataclysmic variables. Astrometric observations with the Fine Guidance Sensors (FGS) on the Hubble
Testing the disk instability model of cataclysmic variables
Context. The disk instability model (DIM) attributes the outbursts of dwarf novae to a thermal-viscous instability of their accretion disk, an instability to which nova-like stars are not subject.
Interstellar Absorption Lines in the Direction of the Cataclysmic Variable SS Cygni
We present an analysis of interstellar absorption lines in high-resolution optical echelle spectra of SS Cyg obtained during an outburst in 2013 June and in archival Hubble Space Telescope and Far
Anomalous Z Cam stars: a response to mass-transfer outbursts
Recent observations of two unusual Z Cam systems, V513 Cas and IW And have shown light curves that seem to contradict the disc-instability model for dwarf novae: outbursts are appearing during
Late-outburst radio flaring in SS Cyg and evidence for a powerful kinetic output channel in cataclysmic variables
Accreting white dwarfs in binary systems known as cataclysmic variables (CVs) have in recent years been shown to produce radio flares during outbursts, qualitatively similar to those observed from


The dwarf nova SS Cygni: what is wrong?
Since the Fine Guiding Sensor (FGS) on the Hubble Space Telescope (HST) was used to measure the distance to SS Cyg to be $166\pm12$ pc, it became apparent that at this distance the disc instability
The Masses and Evolutionary State of the Stars in the Dwarf Nova SS Cygni
The dwarf nova SS Cygni is a close binary star consisting of a K star transferring mass to a white dwarf by way of an accretion disk. We have obtained new spectroscopic observations of SS Cyg. Fits
Distances and absolute magnitudes of dwarf novae: murmurs of period bounce
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
Delays in dwarf novae I: The case of SS Cygni
Using the disc instability model and a simple but physically reasonable model for the X-ray, extreme UV, UV and optical emission of dwarf novae we investigate the time lags observed between the rise
Implications of the HST/FGS parallax of SS Cygni on the disc instability model
We analyse the consequences of the recently measured parallax of SS Cygni (Harrison et al. 1999) on the accretion disc limit cycle model. Using the observed long term light curve of SS Cyg and d =
A Transient Radio Jet in an Erupting Dwarf Nova
Radio observations of a dwarf nova in outburst showing variable flat-spectrum radio emission that is best explained as synchrotron emission originating in a transient jet is presented, suggesting that the disc/jet coupling mechanism is ubiquitous.
On the Accretion Instability in Soft X-Ray Transients
Dwarf nova outbursts are likely caused by a thermal-viscous instability in the accretion disk around the white dwarf, which can occur if the mass transfer rate, , is below a critical value (which
The light curves of soft X‐ray transients
We show that the light curves of soft X-ray transients (SXTs) follow naturally from the disc instability picture, adapted to take account of irradiation by the central X-ray source during the
The disc instability model for X-ray transients: Evidence for truncation and irradiation
The two- disc instability model provides an adequate description of the outbursts of SXTs when both truncation and irradiation are included, and the values for the viscosities in outburst and in quiescence are comparable to those used in CVs.
Accretion disks and periodic outbursts of active galactic nuclei
The local thermal stability of accretion disks around supermassive black holes in active galactic nuclei is examined. Such disks are unstable at radii where the surface temperature is several
