Spectroscopic Observations of Eleven Cataclysmic Variable Candidates Using the Liverpool Telescope.

CAIRNS F.J. and COPPERWHEAT C.M.

Abstract (from CDS):

This paper presents spectroscopic observations of eleven candidate cataclysmic variables (CVs). Observations of the candidates were performed using the Liverpool Telescope and the SPRAT spectrograph, following initial identification from the Gaia Alerts Index. Through line identification, with supporting evidence from Gaia light curves, nine out of the eleven targets show emission features consistent with that of CVs, leading to their classifications as CVs. No obvious emission features are identified in the remaining two, meaning further observations are required for classification.
