| Abstract : | We present our study of Kronberger 55, an open cluster located in our galaxy, to un-
derstand star formation activities. We used optical and near-infrared (NIR) photometric
observations from 1.3m Devasthal Fast Optical Telescope (DFOT) and near-infrared photo-
metric observations from TANSPEC mounted at 3.6m Devasthal Optical Telescope (DOT)
respectively. We have used multiwavelength archival data as well. The age, distance and
extinction of this cluster are evaluated to be ≲5 Myr, ∼3.5 kpc and E(B − V ) ∼1.0 mag
respectively. The identification of Young Stellar Objects (YSOs) is done on the basis of ex-
cess infrared (IR) emission. The inspection of mid-infrared images gives information of the
presence of extended dust, gas emission and outflow activities: one peak is found at the loca-
tion of Kronberger 55 and another 5′.35 southwards to it. The radio continuum emission is
associated with this southern peak. The presence of two clumps with a filamentary structure
is further confirmed by the Herschel sub-millimeter images. Hence this region is promising
candidate of end-dominated collapse. |
