Check out my new paper accepted by the Astrophysical Journal exploring the demographics of the companion population to M-stars in the Orion Nebula Cluster (ONC). With the Hubble Space Telescope, we detected 44 companions (14 new) to M-stars in the ONC, finding no difference in the companion frequency relative to the field population, but a significant difference relative to Taurus-Auriga, demonstrating the effect of environment on the companion population. We also find tentative evidence for a universal mass ratio distribution, consistent across Taurus, the ONC, and the field.
