Journal ArticleDOI
New Evidence for a Coronal Mass Ejection-driven High Frequency Type II Burst near the Sun
TL;DR: In this paper, the authors considered that Type II solar radio bursts originate from plasma waves excited by magnetohydrodynamic (MHD) shocks and converted into radio waves at the local plasma frequency and/or its harmonics.
Journal ArticleDOI
On the usefulness of existing solar wind models for pulsar timing corrections
Caterina Tiburzi,Caterina Tiburzi,Caterina Tiburzi,Joris P. W. Verbiest,Joris P. W. Verbiest,G. Shaifullah,Gemma H. Janssen,Gemma H. Janssen,James M. Anderson,A. Horneffer,J. Künsemöller,Stefan Oslowski,J.Y. Donner,J.Y. Donner,Michael Kramer,Michael Kramer,Anshu Kumari,N. K. Porayko,Pietro Zucca,B. Ciardi,R. J. Dettmar,J.-M. Grießmeier,J.-M. Grießmeier,Matthias Hoeft,M. Serylak,M. Serylak +25 more
TL;DR: In this article, the authors compared the performance of the two-phase model and the spherical model with an optimal data set of observations of pulsar J0034−0534, taken with the German stations of LOFAR.
Journal ArticleDOI
Strength of the Solar Coronal Magnetic field - A Comparison of Independent Estimates Using Contemporaneous Radio and White-light Observations
TL;DR: In this paper, the authors estimated the coronal magnetic field strength during the 23 July 2016 coronal mass ejection (CME) event using i) the flux rope structure of the CME in the whitelight coronagraph images and ii) the band splitting in the associated type of {\sc II} burst.
Journal ArticleDOI
Direct Estimates of the Solar Coronal Magnetic Field Using Contemporaneous Extreme-ultraviolet, Radio, and White-light Observations
TL;DR: In this paper, the authors reported a solar coronal split-band type II radio burst that was observed on 2016 March 16 with the Gauribidanur Radio Spectro-Polarimeter (GRASP) in the frequency range of approx. 80 MHz and 53.3 MHz.
Journal ArticleDOI
The First Low-frequency Radio Observations of the Solar Corona on ≈200 km Long Interferometer Baseline
Mugundhan,R. Ramesh,C. Kathiravan,G. V. S. Gireesh,Anshu Kumari,K. Hariharan,Indrajit V. Barve +6 more
TL;DR: In this article, the authors used a two-element interferometer with a baseline length of ≈200 km, operating at ≈53 MHz, to infer the angular size of the smallest radio source that can be observed in the solar atmosphere.
