Identification spectra of several Northern Hemisphere CV candidates

TL;DR

This study obtained spectral data for six Northern Hemisphere cataclysmic variable candidates, identifying four as likely dwarf novae and providing insights into their observational characteristics, despite challenges with faint sources.

Contribution

The paper presents new spectral observations and archival data analysis of CV candidates, confirming their nature and expanding the catalog of identified dwarf novae.

Findings

Four sources are likely dwarf novae.

Two sources were too faint for spectral identification.

No periodicity was detected in CRTS data.

Abstract

We obtained Calar Alto identification spectra for six cataclysmic variable candidates, and studied archival observations at a range of wavelengths. Two sources were too faint to allow for easy identification by their spectra, and the other four are likely to be dwarf novae. No periodicity was detected for any of the sources on the basis of CRTS data.
