We condueted XMM observations of 5 faint Polars discovered by the Sloan Digital Sky Survey. The X-ray fluxes and spectra show a variety of shock regimes. The lowest accretor has X-ray properties consistent with an origin on the secondary star. The light curves of all systems show large variability, with one showing a deep eclipse, and with some evidence for orbital-related variations in 2 others.

Resumen

Resumen

Hemos llevado a cabo observaciones XMM de 5 polares débiles descubiertas pоr el Sloan Digital Sky Survey. Los llujos de rayos X y los espectros present an una variedad de regímenes de choque. El acrecentador más bajo posee propiedades de rayos X consistentes con un origen en la estrella secundaria. Las curvas de luz de todos los sistemas presentan una alta variabilidad con una de ellas mostrando un profundo eclipse, y en otras dos con evidencias de variaciones relacionadas con la órbita.
