Variable star near UGC 11800 is a new cataclysmic variable
Abstract
A CCD spectrum (range 340-900 nm), obtained on July 28 UT with the Keck I 10-m telescope (+ LRISp), shows that the variable star reported by Baek & Li (IAUC #8574) near UGC 11800 is a new cataclysmic variable. There are no USNO B1.0 stars detected at the location of the CV. The spectrum is characterized by a blue continuum with strong, broad, absorption Balmer lines evident from H_beta to at least H_eta, with H_beta having an equivalent width of 0.5 nm and FWHM of 5.6 nm; the H_alpha feature is less distinct, as an emission core fills up much of the absorption profile.
