Probing Accretion and Outflow in V1180 Cas through High-Resolution Optical Spectroscopy
Tarak Chand, Saurabh Sharma, Koshvendra Singh +9
We present an analysis of a high-resolution optical spectrum of V1180 Cas obtained with HIRES at the W. M. Keck Observatory during a bright photometric state of the source. The spe…
Hot water emission during an outburst in a classical T Tauri star
Zhen Guo, Javier Osses, Vitor Fermiano +34
In this paper, we present observations of an eruptive young star in the Rosette Nebula, identified by the Gaia Science Alerts system using Gaia time series data. We aim to investig…
Gaia24ccy: An outburst followed the footsteps of its predecessor
Koshvendra Singh, Joe P. Ninan, Zhen Guo +25
Accretion-driven outbursts in young stellar objects remain poorly understood, largely limited by a statistically small sample of closely followed-up events. This underscores the im…
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…
NGC 2392 and NGC 4361: Spectroscopic Diagnostics of Planetary Nebula Evolution
Atul Kumar Singh, Saurabh Sharma, Rahul Kumar Anand +3
The study presents a detailed spectroscopic analysis of the planetary nebulae (PNe) NGC~2392 and NGC~4361 using optical spectra obtained from the 2-m Himalayan Chandra Telescope (H…
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…
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…
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…
