High speed photometry of faint cataclysmic variables - VI. Car2, V1040 Cen, Hα075648, IL Nor (Nova Nor 1893), HS Pup (Nova Pup 1963), SDSS J2048-06, CSS 081419-005022 and CSS 112634-100210
Abstract
We have observed eight faint cataclysmic variable stars photometrically. The nova-like Car2 was extensively sampled but showed little variability. V1040 Cen was observed near the end of a dwarf nova outburst and possessed dwarf nova and quasi-periodic oscillations. Hα075648 has strong large amplitude flickering and a possible orbital modulation at 3.49h. The correct identification for the nova remnant IL Nor (Nova Nor 1893) has been established. HS Pup (Nova Pup 1963) has a possible orbital period of 3.244h. SDSS J2048-06 is a low-mass transfer dwarf nova that in quiescence shows slow variations at 7.67h (though poorly sampled with our observations) and an orbital modulation at 87.26 min. The dwarf nova CSS 081419-005022 has an orbital period of 1.796h and the eclipsing dwarf nova CSS 112634-100210 has an orbital period of 1.8581h.
