  • Solar dynamics imaging system a back-end instrument for the proposed NLST 
    Ramesh, K. B; Vasantharaju, N; Hemanth, P; Reardon, K (Springer, 2016-12)
    The Solar Dynamics Imaging System (SDIS) will be one of the focal plane instruments operated at the National Large Solar Telescope (NLST). The prime objective of the instrument is to obtain high spatial and temporal ...
  • Solar G-band observations at Merak, Leh/Ladakh 
    Vasantharaju, N; Dorjey, N; Ravindra, B; Prabhu, K; Rangarajan, K. E; Prabhu Ramkumar, B; Sankarasubramanian, K (Indian Institute of Astrophysics, 2012)
    G-band observations are important for the study of dynamics of magnetic features in the solar photosphere and they are carried out using large telescopes, larger than 30 cm. We installed a 40 cm DFM telescope at one of ...
  • Statistical Study of Magnetic Nonpotential Measures in Confined and Eruptive Flares 
    Vasantharaju, N; Vemareddy, P; Ravindra, B; Doddamani, V. H (IOP Publishing, 2018-06-10)
    Using Solar Dynamics Observatory/Helioseismic and Magnetic Imager vector magnetic field observations, we studied the relation between the degree of magnetic non-potentiality with the observed flare/coronal mass ejection ...
  • Temporal offsets among solar activity indicators 
    Ramesh, K. B; Vasantharaju, N (Springer, 2014-04)
    Temporal offsets between the time series of solar activity indicators provide important clues regarding the physical processes responsible for the cyclic variability in the solar atmosphere. Hysteresis patterns generated ...
