Around 1987, when the 4th edition of Rcat (Rit- ter 1987) was published it was also realized, not least thanks to X-ray observations with EXOSAT, that the distribution of the orbital periods of the synchronized and non-synchronized magnetic CVs, i.e. of the AM Her stars and the intermediate polars, are significantly dif- 22 The Ritter-Kolb Catalogue and its Impact on Research into CVs, LMXBs and related Objects ferent and that this could be accounted for in terms of standard CV evolution by the fact that on average the mass transfer rate in CVs decreases with orbital period (Hameury et al. 1987). keywords: binaries; cvs; kolb; objects; period; ritter; rkcat cache: app01-2818.pdf plain text: app01-2818.txt item: #179 of 1101 id: app01-2820 author: Pretorius, M.

Furthermore, mCVs are luminous X-ray sources, while the correlation between the ratio of optical to X-ray flux and the optical lumi- nosity of non-magnetic CVs, implies that an X-ray flux limit does not introduce as strong a bias against short- period CVs as an optical flux limit (e.g. van Teeseling et al. 1996). keywords: cvs; ips; magnetic; period; polars; space cache: app01-2820.pdf plain text: app01-2820.txt item: #180 of 1101 id: app01-2822 author: Sion, E.

(2010), in section 4 we tabulate and display the current distribution of CVWD surface temperatures versus or- bital period and in the final section, we include some remarks on new HST spectra of the recurrent nova T Pyxidis. An obvious question is: How does the new, shorter dis- tance affect the analysis of Sion et al. (2010) regarding their detection of the WD during quiescence and their derivation of the WD’s surface temperature from the modeling of FUSE + HST STIS spectra? To answer this question, we have carried out model fits using the new distance in the range of 114 pc to 120 pc. keywords: apj; et al; gänsicke; hst; sion; sion et; szkody cache: app01-2822.pdf plain text: app01-2822.txt item: #181 of 1101 id: app01-2825 author: Zharikov, S.; Tovmassian, G. title: CVs Around the Minimum Orbital Period date: 2015 words: 2585 flesch: 68 summary: The large size of the disk and domination of white dwarf radiation in the optical range and the sec- ondarys radiation in the JHK bands in SDSS0804 and SDSS1238 bounce back candidates (Zharikov et al 2013, Aviles et al 2010) lead to the conclusion that the ”stan- dard accretion disk model” (Frank et al. 2002) does not apply to bounce-back systems.

The low accretion in comparison to the mass trans- fer α = Ṁ∗/Ṁ2 ∼ 0.1% may indicate that the white dwarf in AE Aquarii is currently in a super-propeller (Bisikalo & Zhilkin 2012) or ejector phase (Ikhsanov & Beskrovnaya 2012) and that the white dwarf in AE Aquarii may exhibit the same properties as a spun-up radio pulsar (e.g Ikhsanov & Bierman 2006). keywords: aquarii; dwarf; mass; meintjes; mnras cache: app01-2841.pdf plain text: app01-2841.txt item: #191 of 1101 id: app01-2842 author: Latev, G.; Zamanov, R.; Boeva, S.; Stoyanov, K. title: Simultaneous UBVRI Observations of the AE Aquarii Blobs date: 2015 words: 2192 flesch: 64 summary: Abstract We summarize the results of our study of the cataclysmic variable AE Aqr on the basis of simultaneous UBV RI observa- tions.
