Description
Observations with the Wide Field Cameras on BeppoSAX revealed seven
type-I X-ray bursters that failed to exhibit significant levels of
persistent emission. The constraints on the persistent luminosity
simultaneous to the bursts are sometimes lower than what is commonly
observed for type-I bursters. Therefore, a new class of objects is
suggested. Chandra ACIS-S follow-up observations that were carried out
on five of them showed a persistent emission level of 10^(32-33) erg/s.
An observational overview of these sources is presented.
