Post-perihelion Photometric and Spectroscopic Monitoring of the Interstellar Comet 3I/ATLAS
Goldy Ahuja, Shashikiran Ganesh, K. Aravind +12
The third interstellar object, comet 3I/ATLAS, was observed using various Indian telescopes during its post-perihelion evolution. We carried out imaging and spectroscopic observati…
Unveiling the Nature of C/2023 A3 (Tsuchinshan-ATLAS): A Multi-Technique Observational Approach
Goldy Ahuja, Shashikiran Ganesh, Aravind Krishnakumar +3
Comet C/2023 A3 (Tsuchinshan-ATLAS) is a non-periodic dynamically new Oort cloud comet that was discovered independently by Purple Mountain Observatory in China and Asteroid Terres…
Effect of different Non-Gravitational accelerations on the trajectory of Interstellar Comet 3I/ATLAS
Goldy Ahuja, Shashikiran Ganesh
Comet C/2025 N1 or 3I/ATLAS is the third confirmed interstellar object. It has passed perihelion on 2025 October 29, and is currently on a path to leave the solar system. During it…
Dynamical simulation of the Interstellar Comet 3I/ATLAS
Goldy Ahuja, Shashikiran Ganesh
Comet 3I/ATLAS, also known as C/2025 N1, was discovered on 2025 July 1 UT by NASA Asteroid Terrestrial-impact Last Alert System (ATLAS), with a v 58 kms. T…
Long-term monitoring of a dynamically new comet C/2020 V2 (ZTF)
Goldy Ahuja, K. Aravind, Shashikiran Ganesh +5
Comet C/2020 V2 (ZTF) is categorized as a dynamically new long-period comet, making its first approach to the inner Solar system. We have observed this comet for around 32 months (…
Wide-field Polarization Imaging and Numerical Modeling of the Coma and Tail of Comet C/2023 A3 (Tsuchinshan-ATLAS)
Mirza Arnaut, Christian Wöhler, Pritish Halder +3
Imaging polarimetry enables the spatially resolved investigation of cometary dust properties across different morphological structures. While cometary comae have been studied thoro…
Optical spectroscopy of comets using Hanle Echelle Spectrograph (HESP)
K Aravind, Kumar Venkataramani, Shashikiran Ganesh +5
Observing the vibrational/rotational lines in a comet's optical spectrum requires high-resolution spectroscopy, as they are otherwise seen as a blended feature. To achieve this, we…
Long-term spectroscopic monitoring of comet 46P/Wirtanen
K. Aravind, Kumar Venkataramani, Shashikiran Ganesh +2
Jupiter Family Comets (JFCs), having orbital period less than 20 years, provide us with an opportunity to observe their activity and analyse the homogeneity in their coma compositi…
Optical spectroscopy of comets
K. Aravind, Shashikiran Ganesh
Comets are pristine remnants of the Solar system, composed of dust and ice. They remain inactive and undetectable for most of their orbit due to low temperatures. However, as they…
Lately Exposed Amorphous Water Ice on Comet 49P/Arend-Rigaux
B. Sivaraman, V. Venkataraman, A. Kalyaan +2
Comet 49P/ Arend-Rigaux, thought to be a low activity comet since the 1980's was found to be active in its recent apparitions. Recent analysis of the data obtained from Spitzer obs…
