High Dispersion Absorption-line Spectroscopy of AE Aqr
J. Echevarria, R. Connon Smith, R. Costero +2
High-dispersion time-resolved spectroscopy of the unique magnetic cataclysmic variable AE Aqr is presented. A radial velocity analysis of the absorption lines yields K_2 = 168.7+/-…

U Geminorum: a test case for orbital parameters determination
J. Echevarria, E. de la Fuente, R. Costero
High-resolution spectroscopy of U Gem was obtained during quiescence. We did not find a hot spot or gas stream around the outer boundaries of the accretion disk. Instead, we detect…

Determination of the basic parameters of the dwarf nova EY Cygni
J. Echevarria, R. Michel, R. Costero +1
High-dispersion spectroscopy of EY Cyg obtained from data spanning twelve years show, for the first time, the radial velocity curves from both emission and absorption line systems,…
