Abstract:
The aim of this paper is to present the results of photometric
investigations of the central cluster of the W5 E HII region as well
as a follow-up study of the triggered star formation in and around
bright-rimmed clouds (BRCs). We have carried out wide-field UBVIc and
deep VIc photometry of the W5 E HII region. A distance of ∼2.1kpc
and a mean age of ∼1.3Myr have been obtained for the central
cluster. The young stellar objects (YSOs) associated with the region
are identified on the basis of near-infrared and mid-infrared
observations.
Description:
The UBVIc CCD observations of the central region of W5 E have also
been carried out using the 2048x2048pixel2 CCD camera mounted on
the 1.04-m Sampurnanand Telescope (ST) of the Aryabhatta Research
Institute of observational sciencES (ARIES), Nainital, India.
