A search for fast photometric variability in very low mass stars and brown dwarfs

Abstract

We present here I-band time-series photometric studies of a few very low-mass stars (VLMs) and brown dwarfs (BDs) in the young (age of 2-3 Myr) IC348 star-forming region in the Perseus Molecular Cloud. Our main aim is to explore the fast rotating (of time scale of a few hours) BDs and VLMs in the I-band. From our preliminary results, we find significant variability in the young M5 dwarf 2MASS J03443896+3203196 with a rotation period of 16.037 hours.
