Evidence for the gravity-driven and magnetically-regularized gas flows feeding the massive protostellar cluster in Cepheus A

Panigrahy Sandhyarani, Chakali Eswaraiah, Di Li +8

The hierarchical interplay among gravity, magnetic fields, and turbulence in forming massive protostellar clusters remains elusive. We present high-resolution (14 arcsec $\si…

UVIT/AstroSat observation of TW Hya

Prasanta K. Nayak, Mayank Narang, P. Manoj +7

The paper demonstrates the spectroscopic and photometric capabilities of the Ultra-Violet Imaging Telescope (UVIT) to study T-Tauri stars (TTSs). We present the first UVIT/Far-UV (…

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…
