From mid-infrared observations of YSOs, Young et al. (2015) support ages of∼2Myr for IC 348 and.1Myr for NGC 1333.

Our study comprises very low mass stars (.0.2푀) and browndwarfs (.0.08푀, i.e.,.80푀Jup) in three star-forming re-gions: the Orion Nebula Cluster (ONC), NGC 1333, and IC 348.Among young (∼1−3Myr) stars and brown dwarfs, mass is closelycorrelated with spectral type and effective temperature (푇eff); thehydrogen-burning limit of∼0.08푀corresponds to a spectral typeof∼M6 and an effective temperature of∼3000K (Luhman et al.2003; Luhman 2012). In the ONC, we rely on membership and푇effestimations from Robberto et al. (2020); in NGC 1333 and IC 348,we rely on membership and spectral type estimates from Luhmanet al. (2016).

 Rodríguez-Ledesma et al. (2009) performed a comparison of ro-tation among both stellar and substellar-mass YSOs.

Variability among low-mass stars and brown dwarfs in \ic{} has been previously studied by \citet{ghosh_fast_2021}.

 The shortest periods for young brown dwarfs are $\sim 1$~hr \citep{tannock_weather_2021}.
