Descripción
The results of a high temporal resolution spectroscopic monitoring of the
UV Cet type fare stars AD Leo and V1054 Oph are reported. Intermediate
resolution optical spectra of these stars were taken using the IDS
spectrograph of the 2.5 m Isaac Newton Telescope (INT) of El Roque de los
Muchachos Observatory (Spain) during 4 nights (2-5 April 2001). We have
obtained high temporal resolution by taking series of spectra with short
exposure times (15-300 sec) separated only by the CCD readout time (~60 sec).
The great number of spectra observed each night has allowed us to analyse the
temporal evolution of the emission lines and to identify several fares of
different intensity and duration.
