Unveiling the Dual Nature of V1180 Cas: UXor-like Dips and EXor-like Bursts Across a Decade
Tarak Chand, Saurabh Sharma, Koshvendra Singh +15
We present a detailed analysis of the long-term photometric and spectroscopic evolution of V1180 Cas over a decade, aiming to identify the dominant mechanisms behind its variabilit…
Unraveling the Feedback-Regulated Star Formation Activities around the Expanding Galactic MIR Bubble [HKS2019] E71
Aayushi Verma, Saurabh Sharma, Lokesh K. Dewangan +8
We explore the physical environment of the Galactic mid-infrared (MIR) bubble [HKS2019] E71 (hereafter E71) through a multi-wavelength approach. E71 is located at the edge of a fil…
Long-term investigation of an open cluster Berkeley 65
Tarak Chand, Saurabh Sharma, Koshvendra Singh +7
We present a decade-long investigation of a poorly studied cluster, Berkeley 65 (Be 65), using deep optical data from the telescopes of ARIES, Nainital Observatory. We estimate its…
Uncovering the hidden physical structures and protostellar activities in the Low-Metallicity S284-RE region: results from ALMA and JWST
O. R. Jadhav, L. K. Dewangan, Aayushi Verma +4
We present an observational study of the S284-RE region, a low-metallicity area associated with the extended S284 HII region. A thermally supercritical filament (mass 2402 $M…
Investigating the Star-forming Sites in the Outer Galactic Arm
Aayushi Verma, Saurabh Sharma, Lokesh K. Dewangan +7
We aim to investigate the global star formation scenario in star-forming sites AFGL 5157, [FSR2007] 0807 (hereafter FSR0807), [HKS2019] E70 (hereafter E70), [KPS2012] MWSC 0620 (he…
Extraction of YSO Cores and Active Regions near Star-forming Site AFGL 5157
Aayushi Verma, Saurabh Sharma, Lokesh Dewangan
We have carried out a quantitative analysis of the region near star-forming site AFGL 5157 using 'Minimal Spanning Tree' (MST). The analysis reveals th…
Initial results of our spectro-photometric monitoring of XZ Tau
Arpan Ghosh, Saurabh Sharma, Joe Philip Ninan +5
We present here initial results of our spectro-photometric monitoring of XZ Tau. During our monitoring period, XZ Tau exhibited several episodes of brightness variations in timesca…
Cluster Formation in a Filamentary Cloud: The Case of the Stellar Cluster NGC 2316
Saurabh Sharma, Aayushi Verma, Kshitiz Mallick +7
We present a multi-wavelength analysis of the star cluster NGC 2316 and its surroundings. We estimated the physical parameters of the NGC 2316 cluster, including its shape (elongat…
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…
