Do solar decimetric spikes originate in coronal X-ray sources?
, 2009 Context. In the standard solar flare scenario, a large number of particles are accelerated in the corona. Nonthermal electrons emit both X-rays and radio waves.

, 2015 M Dwarfs are becoming increasingly important in the investigation of magnetic fields. These low mass stars span a range of masses that coincide with a change in the internal structure from partly convective to fully convective.

The Astrophysical Journal LettersPolarimetric radio observations of the Sun can provide rich information about emission mechanisms and the propagation medium. For the past five decades, solar polarimetric studies at low radio frequencies have almost always assumed the absence of linear ...

, 1986 Preliminary results of observations of solar coronal bright points acquired simultaneously from ground based observatories at the radio wavelength of 20 cm and in the He I wavelength 10830 line on September 8, 1985, are reported.

The Astrophysical JournalThe solar corona is much hotter than the photosphere and chromosphere, but the physical mechanism responsible for heating the coronal plasma remains unidentified. The thermal microwave emission, which is produced in a strong magnetic field above sunspots,

The Astrophysical Journal LettersWe traced the origin of very-long-periodic pulsations (VLPs) in type-I burst chains on 2024 February 14. Seven successive and repetitive pulsation structures appeared in radio dynamic spectra in the metric waveband, which were simultaneously measured by ...

ABSTRACT RADIO MEASUREMENTS OF CORONAL MAGNETIC FIELDS
, 2008 The measurement of magnetic field strengths in the solar corona using radio observations is reviewed. This is a well established technique that exploits the fact that the electron gyrofrequency for typical coronal magnetic field strengths (100–2000 Gauss)

RADIO MEASUREMENTS OF THE HEIGHT OF STRONG CORONAL MAGNETIC FIELDS ABOVE SUNSPOTS AT THE SOLAR LIMB
, 2006 We measure coronal magnetic field strengths of 1750 G at a height of 8000 km above a large sunspot in NOAA AR 10652 at the west solar limb on 2004 July 29 using coordinated observations with the Very Large Array, the Transition Region and Coronal ...
