  • Automated Detection of Accelerating Solar Eruptions Using Parabolic Hough Transform 
    Ritesh Patel; Pant, V; Priyanka Iyer; Banerjee, D; Mierla, M; West, M. J (Springer, 2021-02)
    Solar eruptions such as coronal mass ejections (CMEs) observed in the inner solar corona (up to 4 R⊙) show acceleration profiles that appear as parabolic ridges in height–time plots. Inspired by the white-light automated ...
  • Automated detection of coronal mass ejections in visible emission line coronagraph (VELC) on-board ADITYA-L1 
    Ritesh Patel; Amareswari, K; Pant, V; Banerjee, D; Sankarasubramanian, K (Cambridge University Press, 2018-02)
    An onboard automated coronal mass ejections (CMEs) detection algorithm has been developed for Visible Emission Line Coronagraph (VELC) onboard ADITYA-L1. The aim of this algorithm is to reduce the load on telemetry by ...
  • Characterizing Spectral Channels of Visible Emission Line Coronagraph of Aditya-L1 
    Ritesh Patel; Megha, A; Shrivastav, Arpit Kumar; Pant, V; Vishnu, M; Sankarasubramanian, K; Banerjee, D (Frontiers, 2021-06)
    Aditya-L1 is India’s first solar mission with the Visible Emission Line Coronagraph (VELC), which consists of three spectral channels taking high-resolution spectroscopic observations of the inner corona up to 1.5 Rʘ at ...
  • Connecting 3D Evolution of Coronal Mass Ejections to Their Source Regions 
    Majumdar, S; Pant, V; Ritesh Patel; Banerjee, D (IOP Publishing, 2020-08-10)
    Since coronal mass ejections (CMEs) are the major drivers of space weather, it is crucial to study their evolution starting from the inner corona. In this work we use graduated cylindrical shell model to study the 3D ...
  • Defining the Middle Corona 
    West, Matthew J; Seaton, D. B; Wexler, David B; Raymond, J. C; Zanna, Giulio Del; Rivera, Yeimy J; Kobelski, Adam R; Chen, Bin; DeForest, Craig; Golub, L; Caspi, Amir; Gilly, Chris R; Kooi, Jason E; Meyer, Karen A; Alterman, Benjamin L; Alzate, Nathalia; Andretta, Vincenzo; Auchere, Frederic; Banerjee, D; Berghmans, David; Chamberlin, Phillip; Chitta, L. P; Downs, Cooper; Giordano, Silvio; Harra, Louise; Higginson, Aleida; Howard, Russell A; Kumar, Pankaj; Mason, Emily; Mason, James Paul; Morton, R. J; Nykyri, Katariina; Ritesh Patel; Rachmeler, Laurel; Reardon, K. P; Reeves, Katharine K; Savage, Sabrina; Thompson, Barbara J; Kooten, Samuel J. Van; Viall, Nicholeen M; Vourlidas, Angelos; Zhukov, Andrei N (Springer, 2023-06)
    The middle corona, the region roughly spanning heliocentric distances from 1.5 to 6 solar radii, encompasses almost all of the influential physical transitions and processes that govern the behavior of coronal outflow ...
  • Evolution of the thermodynamic properties of a coronal mass ejection in the inner Corona 
    Sheoran, Jyoti; Pant, V; Ritesh Patel; Banerjee, D (Frontiers, 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 the ...
  • Imaging and spectral observations of a type-II radio burst revealing the section of the CME-Driven shock that accelerates electrons 
    Majumdar, Satabdwa; Tadepalli, Srikar Paavan; Maity, Samriddhi Sankar; Deshpande, Ketaki; Anshu Kumari; Ritesh Patel; Gopalswamy, Nat (Springer, 2021-04)
    We report on a multi-wavelength analysis of the 26 January 2014 solar eruption involving a coronal mass ejection (CME) and a Type-II radio burst, performed by combining data from various space and ground-based instruments. ...
  • The inner coronagraph on board ADITYA-L1 and automatic detection of CMEs 
    Banerjee, D; Ritesh Patel; Pant, V; ADITYA Team (International Astronomical Union, 2017-07)
    Visible Emission Line Coronagraph (VELC) on board ADITYA-L1 is an internally occulted coronagraph with mirror as its primary objective element. It has a field of view (FOV) starting from 1.05 R –3R. It will observe the ...
  • An Insight into the coupling of CME kinematics in inner and outer corona and the imprint of source regions 
    Majumdar, Satabdwa; Ritesh Patel; Pant, V; Banerjee, D (IOP Publishing, 2021-10-01)
    Despite studying coronal mass ejections (CMEs) for several years, we do not yet have a complete understanding of their kinematics. To this end, it is essential to understand the change in kinematics of the CMEs as they ...
  • Onboard Automated CME Detection Algorithm for the Visible Emission Line Coronagraph on ADITYA-L1 
    Ritesh Patel; Amareswari, K; Pant, v; Banerjee, D; Sankarasubramanian, K; Amit Kumar (Springer, 2018-07)
    ADITYA-L1 is India’s first space mission to study the Sun from the Lagrange 1 position. The Visible Emission Line Coronagraph (VELC) is one of seven payloads on the ADITYA-L1 mission, which is scheduled to be launched ...
  • A statistical study of plasmoids associated with a post-CME current sheet 
    Ritesh Patel; Pant, Vaibhav; Chandrashekhar, K; Banerjee, D (EDP Sciences, 2020-12)
    Context. Coronal mass ejections (CMEs) are often observed to be accompanied by flare, current sheets, and plasmoids/plasma blobs. 2D and 3D numerical simulations and observations reported plasmoids moving upward as well ...
