  ASpitzerinfrared survey ofIC 348 was presented by Muench et al. (2007), identifying this asa cluster with approximately 420 members, of which 118 are ClassII disked members and 31 are (Class 0 or I) protostars.

 The age of NGC 1333 has been estimated in the1−2Myr rangeby Bally et al. (2008); Walawender et al. (2008); Gutermuth et al.(2008).

3/29/21

 The age of IC 348 was estimated in the 2-6 Myr range (luhman2003, bell 2013), with 3 Myr taken as a representative age by Luhmanet al. 2020.

 Kounkel et al. (2018) present a distance to the ONC of 386±3 pcusing an analysis of APOGEE,Gaia, and VLBA data

 In these studies, Rebull et al. have discovered that, withsensitive enough photometric monitoring, nearly all stars displayperiodic photometric variability.

3/24/21

  The optical variabilityof young (∼1−10Myr) low-mass stars was studied by Rebullet al. (2018, 2020) using theKeplerK2 mission, with high-cadence,high-precision single-band photometry.

3/23/21

  Ortiz-León et al. (2018) derive a distanceof321±10pc for IC 348, based on a combined analysis of VLBA andGaiaastrometry. Zucker et al. (2018) report a distance of295±14pcto IC 348, based on a joint Bayesian analysis of Pan-STARRS and2MASS photometry, CO kinematics, andGaiaastrometry. [
