[EAO Time] Spectroscopic confirmation of young substellar objects in L1495

(Abstract)
We propose to obtain Subaru near-infrared spectra to verify a list of young 
candidates of brown dwarf and planet-mass objects in one of the nearby active 
star-forming clouds in Taurus.  Our targets have been selected by narrow-band 
imaging with a newly designed filter to have possible water absorption, a 
characteristic of cool atmospheres. Our prior experience with the filter 
indicates high efficiency to recognize substellar objects. The Subaru 
observations will be the last step to produce a confirmed sample of young 
brown dwarfs and free-floating planets, which will serve as a milestone data 
set to link the formation of stars versus substellar objects.
