  • Analysis of full-disc Hα observations: Carrington maps and filament properties in 1909–2022 
    Chatzistergos, Theodosios; Ermolli, Ilaria; Banerjee, Dipankar; Barata, Teresa; Chouinavas, Ioannis; Falco, Mariachiara; Gafeira, Ricardo; Giorgi, Fabrizio; Hanaoka, Yoichiro; Krivova, Natalie A.; Korokhin, Viktor V.; Lourenço, Ana; Marchenko, Gennady P.; Malherbe, Jean-Marie; Peixinho, Nuno; Romano, Paolo; Sakurai, Takashi (2023-12)
    Context. Full-disc observations of the Sun in the Hα line provide information about the solar chromosphere, and in particular, about the filaments, which are dark and elongated features that lie along magnetic field ...
  • AutoTAB: Automatic Tracking Algorithm for Bipolar Magnetic Regions 
    Sreedevi, Anu; Jha, Bibhuti Kumar; Karak, Bidya Binay; Banerjee, Dipankar (The Astrophysical Journal Supplement Series, 2023-10)
    Bipolar magnetic regions (BMRs) provide crucial information about solar magnetism. They exhibit varying morphology and magnetic properties throughout their lifetime, and studying these properties can provide valuable ...
  • A Coronal Mass Ejection Source Region Catalog and Their Associated Properties 
    Majumdar, Satabdwa; Patel, Ritesh; Pant, Vaibhav; Banerjee, Dipankar; Rawat, Aarushi; Pradhan, Abhas; Singh, Paritosh (The Astrophysical Journal Supplement Series, 2023-09)
    The primary objective of this study is to connect coronal mass ejections (CMEs) to their source regions, primarily to create a CME source region catalog, and secondarily to probe the influence that the source regions have ...
  • Defining the Middle Corona 
    West, Matthew J, et.al; Banerjee, Dipankar (Solar Physics, 2023-06)
    The middle corona, the region roughly spanning heliocentric distances from 1.5 to 6 so lar radii, encompasses almost all of the influential physical transitions and processes that govern the behavior of coronal outflow ...
  • Detection of Solar Filaments Using Suncharts from Kodaikanal Solar Observatory Archive Employing a Clustering Approach 
    Priyadarshi, Aditya; Hegde, Manjunath; Jha, Bibhuti Kumar , et.al.; Banerjee, Dipankar (The Astrophysical Journal, 2023-02)
    With over 100 yr of solar observations, the Kodaikanal Solar Observatory (KoSO) is a one-of-a-kind solar data repository in the world. Among its many data catalogs, the “suncharts” at KoSO are of particular interest. ...
  • Evolution of the thermodynamic properties of a coronal mass ejection in the inner Corona 
    Sheoran, Jyoti; Pant, Vaibhav; Patel, Ritesh; Banerjee, Dipankar (Frontiers in Astronomy and Space Science, 2023-02)
    The thermodynamic evolution of Coronal Mass Ejections (CMEs) in the inner corona (≤1.5 Rsun) is not yet completely understood. In this work, we study the evolution of thermodynamic properties of a CME core observed in ...
  • Extending the sunspot area series from Kodaikanal Solar Observatory 
    Jha, Bibhuti Kumar; Hegde, Manjunath; Priyadarshi, Aditya; Mandal, Sudip; Ravindra, B.; Banerjee, Dipankar (Frontiers in Astronomy and Space Science, 2022-10)
    Kodaikanal Solar Observatory (KoSO) possesses one of world’s longest and homogeneous records of sunspot observations that span more than a century (1904–2017). Interestingly, these observations (originally recorded ...
  • The Fibre Resolved OpticAl and Near-Ultraviolet Czerny–Turner Imaging Spectropolarimeter (FRANCIS) 
    Jess, David B.; Grant, Samuel D.T.; Bate, William; Liu, Jiajia; Jafarzadeh, Shahin; Keys, Peter H.; Vieira, Luís E.A.; Lago, Alisson Dal; Guarnieri, Fernando L.; Christian, Damian J.; Gilliam, Doug; Banerjee, Dipankar (Solar Physics, 2023-12)
    The solar physics community is entering a golden era that is ripe with next-generation ground- and space-based facilities, advanced spectral inversion techniques, and realistic simulations that are becoming more ...
  • Plasma heating induced by tadpole-like downflows in the flaring solar corona 
    Samanta, Tanmoy et al.; Banerjee, Dipankar (Cell Press and YIPA, 2021-02)
    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-arrangement of magnetic field topology ...
