Developing scanning-slit spectrograph for imaging the Sun

Pruthvi, H; Ramesh, K. B; Dhara, Sajal Kumar; Ravindra, B (SPIE--The International Society for Optical Engineering, 2016-08)

For moderate resolution spectroscopy of the Sun, an imaging spectrograph is being developed at Indian Institute of Astrophysics. With this instrument images of the region of interest of the Sun can be obtained with low ...
Filament Eruption in Association with Rotational Motion Near the Filament Footpoints

Dhara, Sajal Kumar; Ravindra, B; Banyal, R. K (Elsevier B.V., 2014-01)

The active region magnetic field surrounding the filament plays an important role in filament formation, their evolution and disruption. We investigated a filament eruption that occurred in southern hemisphere of the Sun ...
Trigger of Successive Filament Eruptions Observed by SDO and STEREO

Dhara, Sajal Kumar; Ravindra, B; Kumar, Pankaj; Banyal, R. K; Mathew, S. K; Joshi, B (Springer, 2017-02)

Using multiwavelength observations from the Solar Dynamics Observatory (SDO) and the Solar Terrestrial Relations Observatory (STEREO), we investigate the mechanism of two successive eruptions (F1 and F2) of a filament in ...
