Dissecting the morphology of star forming complex S193
Rakesh Pandey, Saurabh Sharma, Lokesh Dewangan +5
We have studied a star-forming complex S193 using near-infrared (NIR) observations and other archival data covering optical to radio wavelengths. We identified stellar clusters in…
Optical spectroscopy of Gaia detected protostars with DOT: can we probe protostellar photospheres?
Mayank Narang, Manoj Puravankara, Himanshu Tyagi +7
Optical spectroscopy offers the most direct view of the stellar properties and the accretion indicators. Standard accretion tracers, such as , , and, Ca II triplet lines, a…
Exploring Stellar Cluster and Feedback-driven Star Formation in Galactic Mid-infrared Bubble [HKS2019] E70
Aayushi Verma, Saurabh Sharma, Kshitiz K. Mallick +8
We present a comprehensive analysis of the Galactic mid-infrared (MIR) bubble [HKS2019] E70 (E70) by adopting a multi-wavelength approach to understand the physical environment and…
Post-outburst evolution of bonafide FUor V2493 Cyg: A Spectro-photometric monitoring
Arpan Ghosh, Saurabh Sharma, Joe P. Ninan +11
We present here the results of eight years of our near-simultaneous optical/near-infrared spectro-photometric monitoring of bonafide FUor candidate `V2493 Cyg' starting from 2013 S…
Investigating star formation activity in the Sh 2-61 H II region
Rakesh Pandey, Saurabh Sharma, Lokesh Dewangan +4
Using the multiwavelength data sets, we studied the star formation activity in H II region Sh 2-61 (hereafter S61). We identified a clustering in the region and estimated the membe…
Structural Analysis of Open Cluster Bochum 2
Harmeen Kaur, Saurabh Sharma, Alok Durgapal +5
We present the results from our deep optical photometric observations of Bochum 2 (Boc2) star cluster obtained using the m Devasthal Fast Optical Telescope along with archival…
Quiescence of an Outburst of a Low-Mass Young Stellar Object: LDN1415-IRS
Koshvendra Singh, Devendra K. Ojha, Joe P. Ninan +5
LDN1415-IRS, a low-mass young stellar object (YSO) went into an outburst between 2001 and 2006, illuminating a surrounding nebula, LDN1415-Neb. LDN1415-Neb was found to have bright…
TIRCAM2 Fast Sub-array Readout Mode for Lunar Occultation studies
Milind B. Naik, Devendra K. Ojha, Saurabh Sharma +4
The TIFR Near Infrared Imaging Camera-II (TIRCAM2) is being used at the Devasthal Optical Telescope (DOT) operated by Aryabhatta Research Institute of Observational Sciences (ARIES…
Spectroscopy of 9 eruptive young variables using TANSPEC
Arpan Ghosh, Saurabh Sharma, Joe P. Ninan +8
In recent times, 3.6m Devasthal Optical Telescope (DOT) has installed an optical to near infra-red spectrograph, TANSPEC, which provides spectral coverage from 0.55-2.5 microns. Us…
Teutsch 76: a Deep Near-Infrared Study
Saurabh Sharma, Lokesh Dewangan, Neelam Panwar +9
We have performed a detailed analysis on the Teutsch 76 (T76) open cluster using the deep near-infrared (NIR) observations taken with the TANSPEC instrument mounted on the 3.6m Dev…
Kronberger 55: A Candidate for End-dominated Collapse Scenario
Aayushi Verma, Saurabh Sharma, Lokesh Dewangan +5
Using optical photometric observations from 1.3m Devasthal Fast Optical Telescope and deep near-infrared (NIR) photometric observations from TANSPEC mounted on 3.6m Devasthal Optic…
