Doppler Tomography and Photometry of the Cataclysmic Variable 1RXS J064434.5+334451
J. V. Hernández Santisteban, J. Echevarría, R. Michel +1
We have obtained simultaneous photometric and spectroscopic observations of the cataclysmic variable 1RXS J064434.5+334451. We have calibrated the spectra for slit losses using the…
Photometry of the eclipsing cataclysmic variable SDSS J152419.33+220920.0
R. Michel, J. Echevarria, J. V. Hernandez-Santisteban
Aims. We present new photometry of the faint and poorly studied cataclysmic variable SDSS J152419.33+220920.0, analyze its light curve and provide an accurate ephemeris for this sy…
Exploring the variable stars in the globular cluster NGC5024 (M53): New RR Lyrae and SX Phoenicis stars
A. Arellano Ferro, R. Figuera Jaimes, Sunetra Giridhar +3
We report CCD V and I time series photometry of the globular cluster NGC 5024 (M53). The technique of difference image analysis has been used which enables photometric precisions b…
