[33.11] Infrared Properties of Cataclysmic Variables from 2MASS

Relatively little is known about the infrared (IR) properties of cataclysmic variables (CVs). Fortunately, advances in IR detector technology have made this region of the spectrum much more accessible. Investigating CVs in the IR contributes to our understanding of the properties of key system components that radiate strongly at these wavelengths: the cool outer disk, accretion stream, and secondary star. The Two Micron All Sky Survey (2MASS) is an ongoing project with the goal of imaging the entire sky down to completeness limits of J=15.8, H=15.1, and K=14.3 mag (detection limits are approximately 0.8 mag fainter). This data will provide the first homogeneous and complete sample of infrared photometry for CVs.

We present an analysis of the group IR properties of the approximately 175 CVs currently detected by 2MASS and included in the 2nd Incremental Data Release (March 2000), which covers approximately 50% of the sky. We also provide a comparison of the homogeneous 2MASS JHK magnitudes of these CVs with other published IR magnitudes (where available). The final product of this project will incorporate an IR catalog and atlas of all CVs detected by 2MASS. This catalog will contain a detailed analysis of their group IR properties as well as IR magnitudes and finding charts (and is intended as a companion resource to the invaluable optical CV catalogs of Duerbeck, Downes & Shara, and Downes et al.).
