Abstract:	摘要： ► Support in favour of triggered star formation towards the direction of the two nebulae located at the periphery of the cluster. ► The fraction of disk bearing stars increases towards the periphery of the cluster. ► Evidence in support of the notion that the mechanisms for disk dispersal operate less efficiently for low-mass stars. ► Our result for this region support the claim that the CTTSs and WTTSs are coeval and have indistinguishable properties. In this paper we continued our efforts to understand the star formation scenario in and around the young cluster NGC 1893. We used a sample of the young stellar sources (YSOs) identified on the basis of multiwavelength data (optical, near-infrared (NIR), mid-infrared (MIR) and X-ray) to study the nature of YSOs associated with the region. The identified YSOs show an age spread of ∼5Myr. The YSOs located near the nebulae at the periphery of the cluster are relatively younger in comparison to those located within the cluster region. The present results are in accordance with those obtained by us in previous studies. Other main results from the present study are: (1) the fraction of disk bearing stars increases towards the periphery of the cluster; (2) there is an evidence supporting the notion that the mechanisms for disk dispersal operate less efficiently for low-mass stars; (3) the sample of Class II sources is found to be relatively older in comparison to that of Class III sources. A comparison of various properties of YSOs in the NGC 1893 region with those in the Tr 37/IC 1396 region is also discussed. 出版者： Elsevier B.V 出版日期： 2013-02 出處： New astronomy, 2013-02, Vol.19, p.1-9 資源來源： Elsevier ScienceDirect Journals 版權： 2012 Elsevier B.V. 識別號： ISSN: 1384-1076 識別號： EISSN: 1384-1092 識別號： DOI: 10.1016/j.newast.2012.07.004
