TL;DR
This paper reports a deep IZ photometric survey of the Pleiades cluster, identifying substellar candidates with masses between 0.075 and 0.03 solar masses, contributing to understanding low-mass objects in clusters.
Contribution
It provides the first deep CCD IZ survey of the Pleiades, detecting substellar objects down to 0.03 solar masses with detailed photometric analysis.
Findings
Detected substellar candidates with masses as low as 0.03 Msol.
Provided detailed photometric data and finder charts for the Pleiades cluster.
Extended the known mass range of objects in the cluster.
Abstract
We present the results of a deep CCD-based IZ photometric survey of a ~1 sq. deg area in the central region of the Pleiades Galactic open cluster. The magnitude coverage of our survey (from I~17.5 down to 22) allows us to detect substellar candidates with masses between 0.075 and 0.03 Msol. Details of the photometric reduction and selection criteria are given. Finder charts prepared from the I-band images are provided.
