A search for radius inflation among active M-dwarfs in Praesepe

Rotation periods from Kepler K2 are combined with projected rotation velocities from the WIYN 3.5-m telescope, to determine projected radii for fast-rotating, low-mass (0.15 \leq M/M_{\odot} \leq 0.6) members of the Praesepe cluster. A maximum likelihood analysis that accounts for observational uncertainties, binarity and censored data, yields marginal evidence for... Show more
