| Abstract: |
We present our spectroscopic program aimed to study some new interesting features recently discovered in the
Magellanic Cloud System. These were revealed by the spatial distribution of OB-type candidate stars selected
based on UV, optical, and IR photometry and proper motions from existing large-area catalogs. As a pilot study
of our project, we are studying OB-star candidates in the Leading Arm (LA) of the Magellanic Stream, a gaseous
tidal structure with no stellar counterpart known so far. Our targets group in three clumps near regions of high
HI density in the LA. If confirmed, these young stars would evidence recent star formation in the LA, and they
would help better understand and constrain the formation of the LA and its interactions with the Milky Way. |
