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.

The Evolution of Cataclysmic Variables [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractUsing Eggletons code the evolution of cataclysmic variables (CVs) is investigated. CVs might suffer the loss of mass and angular momentum during their evolution, we present the models of CVs with mass loss and angular momentum loss (AML) due to gravitation wave radiation (GR) and/or magnetic braking (MB).

Deep Segregation: Informality, Trust and the Making of Discrimination in Markets

Antipode, Volume 58, Issue 4, July 2026.
ABSTRACT This article advances the concept of deep segregation to theorise how social exclusion is produced through the everyday organisation of market access rather than through spatial separation alone. Deep segregation refers to a relational and processual form of segregation constituted through segmented routes of access, intermediary networks and ...

Advancing Robust Governance in Turbulent Times: The Role of Multi‐Level Governance, Hybrid Governance, and Negotiated Societal Intelligence

Public Administration, Volume 104, Issue 2, Page 251-265, June 2026.
ABSTRACT New research argues that robust governance based on flexible adaptation and proactive innovation is needed in order to uphold core public functions, purposes, and values in times of societal turbulence. However, we have limited knowledge of the conditions for enhancing robust governance.

Could cataclysmic variables be sources of gravitational waves?

The detection of gravitational waves has started the field of multi-messenger gravitational wave astronomy. Cataclysmic variables are binary systems that are candidates for gravitational wave emission in the frequency band of space based interferometer ...

The component masses of the cataclysmic variable V347 Puppis [PDF]

, 2005
We present time-resolved spectroscopy and photometry of the double-lined eclipsing cataclysmic variable V347 Pup (=LB 1800). There is evidence of irradiation on the inner hemisphere of the secondary star, which we correct for using a model to give a ...

Cataclysmic Variable Stars [PDF]

Highlights of Astronomy, 1998
The evolution of single stars on and away from the main sequence is well understood. A degenerate core is formed in a star as the star leaves the main sequence and expands to a giant with a radius typically 50 - 500 Ro . Observationally it is known that most stars are members of binary systems, and among these many have orbital periods less than 100 y.

Teaching New Religious Movements Historically: Distance, Empathy, and Cults in the Classroom

Teaching Theology &Religion, Volume 29, Issue 1, Page 46-54, June 2026.
ABSTRACT Resistance to understanding the beliefs of modern New Religious Movements (NRMs) is well‐known to those who teach in the area. This paper builds on Eugene Gallagher's repurposing of “methodological belief” for college classes on NRMs by suggesting that scholars and teachers in the field of religious studies engage methods and content drawn ...
