The golden age of cataclysmic variables and related objects V concluding remarks IV

, 2021
The cataclysmic variables continue to represent important part of modern astrophysics, as demonstrated, already fifth time, by the conference Golden Age of Cataclysmic Variables and Related Objects V held on Mondello (Palermo) in September ...

eROSITA selection of new period-bounce cataclysmic variables

Astronomy & Astrophysics
Context. Between 40% and 80% of cataclysmic variables (CVs) are expected to have evolved past the period-minimum and contain a degenerate donor. However, observational surveys for CVs have only been able to detect a few of these highly evolved “period ...

Broad-Band Variability in Accreting Compact Objects

Acta Polytechnica CTU Proceedings, 2015
Cataclysmic variable stars are in many ways similar to X-ray binaries. Both types of systems possess an accretion disk, which in most cases can reach the surface (or event horizon) of the central compact object.

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

Astronomische Nachrichten, Volume 347, Issue 6, July 2026.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

SWSex Stars, Old Novae, and the Evolution of Cataclysmic Variables

Acta Polytechnica CTU Proceedings, 2015
The population of cataclysmic variables with orbital periods right above the period gap are dominated by systems with extremely high mass transfer rates, the so-called SW Sextantis stars.

Minute-Cadence Observations of the LAMOST Fields with the TMTS: IV—Catalog of Cataclysmic Variables from the First 3-yr Survey

Universe
The Tsinghua University–Ma Huateng Telescopes for Survey (TMTS) started to monitor the LAMOST plates in 2020, leading to the discovery of numerous short-period eclipsing binaries, peculiar pulsators, flare stars, and other variable objects.

Cataclysmic variables from SRG/eROSITA: New systems from eRASS1

Astronomy & Astrophysics
Context. The X-ray all-sky surveys performed with eROSITA on the Spektrum-Roentgen-Gamma (SRG) mission offer a unique opportunity to generate large samples of all kinds of X-ray emitters.

Study of Cataclysmic Variables with the Satellites LOFT and Gaia

Acta Polytechnica CTU Proceedings, 2015
The goal of this paper is to discuss the capabilities of ESA satellite missions Gaia (already in space) and LOFT (considered for the ESA M4 slot) for investigation of cataclysmic variables (CVs).

The End of Self‐Regulation: Will the Football Governance Act 2025 Fix the National Game?

The Modern Law Review, Volume 89, Issue 4, Page 628-658, July 2026.
The Football Governance Act 2025 is a watershed. It upends the model of self‐regulation that has defined how the game has been run in England and Wales for over a century‐and‐a‐half. The newly created Independent Football Regulator will exercise control over clubs, owners, and competition organisers.
