On the Nature of Collinder 121: Insights from the Low-Mass Pre-Main Sequence
Ben Burningham, Tim Naylor, R. D. Jeffries +1
We present a VI photometric catalogue towards the open cluster Cr 121. XMM-Newton and ROSAT data are used to discover a low-mass pre-main sequence (PMS) along this sight-line. de Z…
