Faint Cataclysmic Variables in Quiescence: Globular Cluster and Field Surveys
Current evolutionary models imply that most Cataclysmic Variables (CVs) have Porb < 2 hours and are Dwarf Nova (DN) systems that are quiescent most of the time. Observations of nearby quiescent DN find that the UV spectrum is dominated by the hot white dwarf (WD), indicating that it provides a significant fraction of the optical light in addition to the quiescent disk and main sequence companio...
متن کاملDynamical Formation of Close Binaries in Globular Clusters Ii: Cataclysmic Variables
We answer the long-standing question of which production mechanism is responsible for the cataclysmic variables (CVs) in globular clusters. Arguments have been given that range from mostly primordial presence to a significant contribution of later dynamical formation in close stellar encounters. We conclude, based on a thorough analysis of a homogeneous Chandra data set, that the majority of CV...
متن کاملCataclysmic Variables in Globular Clusters, the Galactic Center, and Local Space
We compare the X-ray spectra and luminosities, in the 2-8 keV band, of known and suspected cataclysmic variables (CVs) in different environments, assessing the nature of these source populations. These objects include nearby CVs observed with ASCA; the Galactic Center X-ray source population identified by Muno et al.; and likely CVs identified in globular clusters. Both of the latter have been ...
متن کاملEUVE Observations of Nonmagnetic Cataclysmic Variables
We summarize EUVE ’s contribution to the study of the boundary layer emission of high accretion-rate nonmagnetic cataclysmic variables, especially the dwarf novae SS Cyg, U Gem, VW Hyi, and OY Car in outburst. We discuss the optical and EUV light curves of dwarf nova outbursts, the quasi-coherent oscillations of the EUV flux of SS Cyg, the EUV spectra of dwarf novae, and the future of EUV obser...
متن کاملLyrae Variables in Globular Clusters and Nearby
I point out that the Oosterhoff dichotomy for globular cluster and field RR Lyrae (RRL) stars may place the strongest constraints so far on the number of dwarf spheroidal-like protogalactic fragments that may have contributed to the formation of the Galactic halo. The first calibration of the RRL period-luminosity relation in I, J , H, K taking evolutionary effects into account is provided. Pro...
