Abstract

CONCLUSIONS Most intermediate bursts are observed from low luminosity sources and are interpreted as long pure He bursts. If no H is accreted, they are consistent with the burning of a slowly accreted, thick He layer, in Ultra Compact X-ray Binaries (UCXB) where the donor star is probably a degenerated helium white dwarf. Of special interest are bursters showing events with very different durations, thus allowing us to study transitions between different nuclear burning regimes. Depending on the actual accretion rate, either the burning of a large amount of H is triggered by an He flash, or a large column of He is triggered by weak H ignition. Relation with superbursts…?
