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…
Investigation of Hourglass-shaped Magnetic fields in the G35.20-0.74 Star-Forming Complex
O. R. Jadhav, L. K. Dewangan, A. K. Maity +7
To investigate the role of magnetic fields toward the G35N and G35S sub-regions in the G35.20-0.74 star-forming complex, we utilized multi-wavelength polarimetric observations from…
Unveiling an Hourglass-Shaped Magnetic Field toward IRDC G351.77-0.53
O. R. Jadhav, L. K. Dewangan, I. I. Zinchenko +5
We present the SOFIA/HAWC+ 214 m polarimetric observations toward the infrared dark cloud G351.77-0.53 (hereafter G351), complemented by existing multi-wavelength data sets. Inf…
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…
Investigating the Influence of Radiative Feedback in Bright-Rimmed Cloud 44
Rishi C, Neelam Panwar, Thomas J. Haworth +9
Radiative feedback from massive stars plays a central role in the evolution of molecular clouds and the interstellar medium. This paper presents a multi-wavelength analysis of the…
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…
Are Kronberger 80 and/or Kronberger 82 regions PeVatron candidates for LHAASO J2108+5157?
Akash Gupta, Eduardo De La Fuente, Ram K. Yadav +13
High-energy gamma rays have been detected in the region of LHAASO~J2108+5157 by the Fermi--LAT, HAWC and LHAASO-KM2A observatories. Cygnus~OB2 in Cygnus--X has been confirmed as th…
Investigating Embedded Structures and Gas Kinematics in the IRDC Hosting Bubble N59-North
A. K. Maity, L. K. Dewangan, O. R. Jadhav +5
We present a multi-wavelength study of an extended area hosting the bubble N59-North to explore the physical processes driving massive star formation (MSF). The Spitzer 8 m imag…
Unveiling Physical Conditions and Star Formation Processes in the G47 Filamentary Cloud
O. R. Jadhav, L. K. Dewangan, A. Haj Ismail +6
We present a multi-wavelength study of the filamentary cloud G47 (d 4.44 kpc), which hosts the mid-infrared bubbles N98, B1, and B2. The SMGPS 1.3 GHz continuum map detects i…
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…
Low-mass stellar and substellar content of the young cluster Berkeley 59
Neelam Panwar, Rishi C., Saurabh Sharma +4
We present a multi-wavelength analysis of the young star cluster Berkeley 59 (Be 59) based on the data and deep infrared (IR) observations with the 3.58-m Telescopio Naziona…
Nobeyama Cygnus-X Survey: Physical Properties of CO clumps in DR-6(W), DR-9 and DR-13S regions
I. Toledano--Juárez, E. de la Fuente, K. Kawata +10
Cygnus-X is considered a region of interest for high-energy astrophysics, since the Cygnus OB2 association has been confirmed as a PeVatron in the Cygnus cocoon. In this research n…
