Augmentation of the Gauribidanur radioheliograph for observations of circularly polarized emission from the solar corona at low radio frequencies
Sayuf Shaik, Kathiravan C, Gireesh G. V. S +4
The magnetic field strengths (B) in the solar photosphere are routinely measured using the Zeeman effect. However, such measurements are not available in the solar chromosphere and…
Relative Strengths of Fundamental and Harmonic Emissions of Solar Radio Type II Bursts
Rishikesh G. Jha, K. Sasikumar Raja, R. Ramesh +2
Solar radio type II bursts are slow-drifting bursts that exhibit various distinct features such as Fundamental (F) and Harmonic (H) emissions, band-splitting, and discrete fine str…
Radio, X-ray and extreme-ultraviolet observations of weak energy releases in the `quiet' Sun
R. Ramesh, C. Kathiravan, N. P. S. Mithun +1
We analyzed ground-based low frequency (100\,MHz) radio spectral and imaging data of the solar corona obtained with the facilities in the Gauribidanur observatory during the sam…
Radio Interferometric Observations of the Sun Using Commercial Dish TV Antennas
G. V. S. Gireesh, C. Kathiravan, Indrajit V. Barve +1
The radio astronomy group in the Indian Institute of Astrophysics (IIA) has been carrying out routine observations of radio emission from the solar corona at low frequencies (${\ap…
Solar Radio Spectro-polarimetry (50-500 MHz) : Design and Development of Cross-Polarized Log-Periodic Dipole antenna and configuration of receiver system
Anshu Kumari, G. V. S. Gireesh, C. Kathiravan +2
A radio spectro-polarimeter was developed at the Gauribidanur radio observatory to study the characteristics of the polarized radio waves that are emitted by the impetuous solar co…
Design and performance of a low frequency cross-polarized log-periodic dipole antenna
K. Sasikumar Raja, C. Kathiravan, R. Ramesh +2
We report the design and performance of a cross-polarized log-periodic dipole (CLPD) antenna for observations of polarized radio emission from the solar corona at low frequencies.…
An estimate of the magnetic field strength associated with a solar coronal mass ejection from low frequency radio observations
K. Sasikumar Raja, R. Ramesh, K. Hariharan +2
We report ground based, low frequency heliograph (80 MHz), spectral (85-35 MHz) and polarimeter (80 and 40 MHz) observations of drifting, non-thermal radio continuum associated wit…
