Photometrically determined membership of the young, open cluster IC 2391.

ROLLESTON W.R.J. and BYRNE P.B.

Abstract (from CDS):

New 4-colour BV(RI)KC CCD photometry to a limiting magnitude of V≃19 is presented for 1428 objects observed towards the direction of the young, open cluster IC 2391. We observed 36 (2'x3') fields within 17 arcmin of the nominal cluster core. By fitting the theoretical isochrones of D'Antona & Mazzitelli (1994ApJS...90..467D) to a combination of colour-magnitude and colour-colour diagrams, we have identified 17 stars as probable cluster members with a further 85 stars as possible members. The brightness distribution of low-mass members is compared with the luminosity function observed for the Pleiades and we estimate that the contamination due to background giants should be small.
