TESS Light Curves of Cataclysmic Variables. VI. Intermediate Polars

The Astrophysical Journal Supplement Series
The long and (almost) continuous high-cadence light curves provided by the TESS space mission are ideally suited to study in detail brightness variations in stellar sources on the broad range of timescales between minutes and months.

Telescope and Researcher Potential of Turkey for Collaboration in CV Studies

Open Astronomy, 2012
Turkish astronomical community has witnessed the construction of several telescopes in the last 10 years. These telescopes and the potential of young researchers in the country motivated this poster presentation which aims to receive attention for ...

X-rays from cataclysmic variables [PDF]

, 2006
Cataclysmic Variables are a distinct class of interacting binaries, transferring mass from a donor star to a degenerate accretor, a white dwarf. We here review X-ray observations of these systems, with some emphasis on what has been achieved in the last ...

A Broadband Search for Coherent Radio Emission in Cataclysmic Variables

The Astrophysical Journal
Radio observations of cataclysmic variables have revealed a variety of behaviors. From some systems, we see bright unpolarized radio flares occurring during dwarf nova outbursts, consistent with synchrotron emission from jets.

The Evolution of Cataclysmic Variables under Various Magnetic Braking Prescriptions

The Astrophysical Journal
Recent studies have revealed discrepancies between observations and the predictions of the standard magnetic braking (MB). Although alternative models have been broadly discussed in neutron star binaries, they have not been systematically tested in ...

Kilonova and progenitor properties of merger-driven gamma-ray bursts

Astronomy & Astrophysics
Context. Gamma-ray burst (GRB) prompt and afterglow emission, as well as kilonova (KN) emission, are the expected electromagnetic (EM) counterparts of binary neutron star (BNS) and neutron star-black hole (NSBH) mergers.

A very rapidly rotating white dwarf in nova YZ Reticuli

Astronomy & Astrophysics
YZ Ret (Nova Reticuli 2020) is the first VY Scl-type nova-like variable observed to have undergone a classical nova eruption. Following the outburst, a timing analysis of 20-s cadence TESS data revealed a periodicity at approximately 42 s, suggesting its

Properties of nova population models. - The reaction of low-mass stars to anisotropic irradiation and its implications for the secular evolution of cataclysmic binaries. - On the outburst behaviour of dwarf novae above the period gap (P > 3 hours)

, 1995
A semi-analytic model for the reaction of a low-mass star to anisotropic irradiation of low incident flux is presented. By applying this model to the donor star of cataclysmic binaries (CBs) it is shown that CBs are likely to be unstable against ...

Outburst catalogue of cataclysmic variables

, 2016
The properties of the cataclysmic variables in this catalogue are derived from the long-term optical light curves from the Catalina Real-time Transient Survey, as well as colour information and orbital parameters from the SDSS, 2MASS, UKIDSS, ROSAT ...
