Developement of a stabilized Fabry-Perot etalon based calibrator for Hanle Echelle Spectrograph (HESP)
Tanya Das, Ravinder K. Banyal, Sivarani T. +1
Accurate wavelength calibration is an important factor for any measurement with high resolution spectrographs. Stellar spectrum comprises of discrete absorption or emission lines w…
Sunspot Drawings at Kodaikanal Observatory: A Representative Results on Hemispheric Sunspot Numbers and Area Measurements
Ravindra B., Kumaravel Pichamani, Selvendran R. +4
The importance of the periodicity in sunspot appearance was well recognized by the mid of 19th century. Several observatories around the globe have made the record of sunspots in t…
Performance of a crystalline silicon photovoltaic power plant during sandstorms
B. Ravindra
Solar photovoltaic power generation has achieved grid parity in a number of countries during the last decade. This revolution has begun in countries where the solar radiation inten…
Prominence eruption initiated by helical kink-instability of an embedded flux rope
P. Vemareddy, N. Gopalswamy, B. Ravindra
We study the triggering mechanism of a limb-prominence eruption and the associated coronal mass ejection near AR 12342 using SDO and LASCO/SOHO observations. The prominence is seen…
Long term study of the solar filaments from the Synoptic Maps as derived from Spectroheliograms of Kodaikanal Observatory
Subhamoy Chatterjee, Manjunath Hegde, Dipankar Banerjee +1
The century long (1914-2007) (656.28 nm) spectroheliograms from Kodaikanal Solar Observatory (KSO) have been recently digitised. Using these newly calibrated, processed image…
Analysing the effects of apodizing windows on local correlation tracking using Nirvana simulations of convection
Rohan E. Louis, B. Ravindra, Manolis K. Georgoulis +1
We employ different shapes of apodizing windows in the local correlation tracking (LCT) routine to retrieve horizontal velocities using numerical simulations of convection. LCT was…
