RESEARCH:

  • Seismology of the solar atmosphere
    • Acoustic waves as probe of dynamics of the photosphere/chromosphere
    • Forecasting of solar transient events using seismic data (acoustic waves).
    • Internal gravity waves a probe of flows in the solar atmosphere.
  • Analysis of long baseline data, current and archival data from SDO/HMI, SOHO/MDI, GOLF, and GONG instruments.
  • Working on sun-as-a-star data to extend the techniques used in the seismic probing of the solar atmosphere, to other stars.
  • Using sun-as-a-star data set, we are also exploring alternate Fourier analysis techniques to detect g-modes.
  • Data analysis and visualization techniques
