    Abstract

    We report on the detection of a new sample of objects, in the Large Magellanic Cloud (LMC), that likely show signatures of the B[e] phenomenon. The discovery of this sample was a by-product of our extensive low-resolution optical spectroscopic survey of post-Asymptotic Giant Branch (post-AGB) candidates in the LMC. It is known that post-AGB binaries are surrounded by a stable, dusty disc similar to that observed in objects that show the B[e] phenomenon. A few of the already known LMC objects that display the B[e] phenomenon were therefore recovered in our survey. However, interestingly, we found several other objects, spread across various evolutionary phases, with signatures of the B[e] phenomenon. Our observations corroborates the fact that the B[e] phenomenon can be active during several phases of stellar evolution. On analyzing the SED of our new sample of likely B[e] candidates, we found that all these objects show the presence of a dusty disc. Here we present a preliminary list and study on these new B[e] candidates.
