Investigating 2M1155−79B: A Nearby, Young, Low-mass Star Actively Accreting from a Nearly Edge-on, Dusty Disk

We investigate the nature of an unusually faint member $\epsilon$ Cha Association ($D\sim100$ pc, age $\sim5$ Myr), nearest region star formation $<$8 Myr. This object, 2MASS J11550336-7919147 (2M1155$-$79B), is a wide ($\sim$580 AU) separation, comoving companion to low-mass (M3) J11550485-7919108 (2M1155$-$79A). present near-infrared spectra both components, along with analysis photometry from Gaia EDR3, 2MASS, VHS, and WISE. The near-IR spectrum 2M1155$-$79B displays strong He I 1.083 emission, sign active accretion and/or accretion-driven winds circumstellar disk. Analysis WISE archival data reveals that mid-infrared excess previously associated 2M1155$-$79A instead originates disk surrounding 2M1155$-$79B. Based on these results, as well radiative transfer modeling its optical/IR spectral energy distribution, we conclude most likely young, late-M, partially obscured by, actively accreting from, nearly edge-on would place among rare group nearby ($D\lesssim100$ pc), young (age $<$10 Myr) mid-M stars are orbited by highly inclined protoplanetary disks. Like systems, system particularly promising subject for studies planet around stars.
