Model Atmospheres for Irradiated Stars in pre-Cataclysmic Variables
, 2004 Model atmospheres have been computed for M dwarfs that are strongly irradiated by nearby hot companions. A variety of primary and secondary spectral types are explored in addition to models specific to four known systems: GD 245, NN Ser, AA Dor, and UU ...

Winds from Cataclysmic Variables [PDF]
International Astronomical Union Colloquium, 1997 AbstractThe winds associated with high states of non-magnetic (diskaccreting) cataclysmic variables are described and discussed. A quick summary of the basic phenomenology is given, and followed by a presentation of some of the more important recent developments in our understanding.

Crisis of imagination/(re)imaginations for a (climate) crisis
Transactions of the Institute of British Geographers, Volume 50, Issue 4, December 2025.Abstract This themed intervention emerges from a Chair's Plenary during the Royal Geographical Society (with IBG) Annual Conference 2023 on the theme of ‘Climate Changed Geographies’ and addresses geographers and allied social scientists. Drawing on Amitav Ghosh's provocation, it asks if our work on climate change is facing a crisis of imagination ...

Temporary Equilibrium Mass Transfer Rate in Cataclysmic Variables?
The Astrophysical JournalThe separation of a binary system increases or decreases over time, governed by angular momentum (AM) changes. In cataclysmic variables (CVs), Roche-lobe overflow from the red dwarf (RD) to the white dwarf (WD) redistributes AM within the system through ...

Cataclysmic variables in Globular clusters: First results on the analysis of the MOCCA simulations database [PDF]
, 2016 In this first investigation of the MOCCA database with respect to cataclysmic variables, we found that for models with Kroupa initial distributions, considering the standard value of the efficiency of the common-envelope phase adopted in BSE, no single ...

Cyclical Period Changes in Cataclysmic Variables: A Statistical Study
The Astrophysical JournalWe report the results of a statistical study of cyclical period changes in cataclysmic variables (CVs). Assuming the third-body hypothesis as the cause of period changes, we estimate the third-body mass, m _3 , and its separation from the binary, a _3 ...

DETERMINATION OF THE ORIENTATION OF THE ACCRETION COLUMNS IN MAGNETIC CATACLYSMIC VARIABLES
Odessa Astronomical Publications, 2017 Methods for the determination of the orientation of accretion columns in magnetic cataclysmic variables based on the observations of the circular and linear polarization, X-Ray flux and profiles of emission lines are discussed.
