Cataclysmic Variables from SDSS. VIII. The Final Year (2007-2008)

TL;DR

This paper completes the SDSS CV series by presenting 33 new systems, including known and newly identified types, with follow-up data confirming candidates and providing a comprehensive CV catalog.

Contribution

It provides the final set of SDSS-identified CVs, confirms candidate types, and offers an extensive, updated catalog of 285 SDSS CVs with spectra and online data access.

Findings

Identification of 33 CVs from SDSS data.

Confirmation of a polar candidate and tentative periods for some CVs.

A comprehensive, publicly accessible CV catalog with spectra.

Abstract

This paper completes the series of cataclysmic variables (CVs) identified from the Sloan Digital Sky Survey I/II. The coordinates, magnitudes and spectra of 33 CVs are presented. Among the 33 are eight systems known previous to SDSS (CT Ser, DO Leo, HK Leo, IR Com, V849 Her, V405 Peg, PG1230+226 and HS0943+1404), as well as nine objects recently found through various photometric surveys. Among the systems identified since the SDSS are two polar candidates, two intermediate polar candidates and one candidate for containing a pulsating white dwarf. Our followup data have confirmed a polar candidate from Paper VII and determined tentative periods for three of the newly identified CVs. A complete summary table of the 285 CVs with spectra from SDSS I/II is presented as well as a link to an online table of all known CVs from both photometry and spectroscopy that will continue to be updated as future data appear.
