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…

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…

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…
