Optical and near-infrared spectroscopy of Nova V2891 Cygni: evidence for shock-induced dust formation
Vipin Kumar, Mudit K. Srivastava, Dipankar P. K. Banerjee +6
We present multi-epoch optical and near-infrared observations of the highly reddened, \pion{Fe}{ii} class slow nova V2891 Cygni. The observations span 15 months since its discovery…
Evolution of the Sun's activity and the poleward transport of remnant magnetic flux in Cycles 21--24
Alexander V. Mordvinov, Bidya Binay Karak, Dipankar Banerjee +4
Detailed study of the solar magnetic field is crucial to understand its generation, transport and reversals. The timing of the reversals may have implications on space weather and…
The Remarkable Spin-down and Ultra-fast Outflows of the Highly-Pulsed Supersoft Source of Nova Hercules 2021
Jeremy J. Drake, Jan-Uwe Ness, Kim L. Page +12
Nova Her 2021 (V1674 Her), which erupted on 2021 June 12, reached naked-eye brightness and has been detected from radio to -rays. An extremely fast optical decline of 2 magnitud…
An Insight into the Coupling of CME Kinematics in Inner and Outer Corona and the Imprint of Source Regions
Satabdwa Majumdar, Ritesh Patel, Vaibhav Pant +1
Despite studying Coronal Mass Ejections (CMEs) for several years, we are yet to have a complete understanding of their kinematics. In this regard, the change in kinematics of the C…
Solar Cycle Evolution of Filaments over a Century: Investigations with the Meudon and McIntosh Hand-drawn Archives
Rakesh Mazumder, Subhamoy Chatterjee, Dibyendu Nandy +1
Hand-drawn synoptic maps from the Meudon Observatory (1919 onwards) and the McIntosh archive (1967 onwards) are two important sources of long-term, manually recorded filament obser…
Characterizing Spectral Channels of Visible Emission Line Coronagraph of Aditya-L1
Ritesh Patel, Megha A., Arpit Kumar Shrivastav +4
Aditya-L1 is India's first solar mission with Visible Emission Line Coronagraph (VELC) consisting of three spectral channels taking high-resolution spectroscopic observations of th…
Plasma Heating Induced by Tadpole-Like Downflows in the Flaring Solar Corona
Tanmoy Samanta, Hui Tian, Bin Chen +4
As one of the most spectacular energy release events in the solar system, solar flares are generally powered by magnetic reconnection in the solar corona. As a result of the re-arr…
Measurements of Solar Differential Rotation Using the Century Long Kodaikanal Sunspot Data
Bibhuti Kumar Jha, Aditya Priyadarshi, Sudip Mandal +2
The rotational profile of the Sun is considered to be one of the key inputs in a solar dynamo model. Hence, precise and long-term measurements of this quantity is important for our…
