Deriving Large Coronal Magnetic Loop Parameters Using LOFAR J burst Observations

Jinge Zhang, Hamish A. S. Reid, Vratislav Krupar +3

Large coronal loops around one solar radius in altitude are an important connection between the solar wind and the low solar corona. However, their plasma properties are ill-define…

Interferometric imaging of the type IIIb and U radio bursts observed with LOFAR on 22 August 2017

Bartosz Dabrowski, Katarzyna Mikula, Pawel Flisek +18

The Sun is the source of different types of radio bursts that are associated with solar flares, for example. Among the most frequently observed phenomena are type III solar bursts.…

Recombination of hot ionized nebulae: The old planetary nebula around V4334 Sgr (Sakurai's star)

Martin Reichel, Stefan Kimeswenger, Peter A. M. van Hoof +5

After becoming ionized, low-density astrophysical plasmas will begin a process of slow recombination. Models for this still have significant uncertainties. The recombination cannot…

Lithium in coalesced non-compact stars

Tomek Kamiński, Mirek Schmidt, Marcin Hajduk +3

Context. Galactic red novae are thought to be produced in stellar mergers between non-compact stars, such as main-sequence stars and cool giants. They are hoped to help in explaini…

Imaging of the Quiet Sun in the Frequency Range of 20-80 MHz

PeiJin Zhang, Pietro Zucca, Kamen Kozarev +7

Radio emission of the quiet Sun is considered to be due to thermal bremsstrahlung emission of the hot solar atmosphere. The properties of the quiet Sun in the microwave band have b…

Exploring the circular polarisation of low-frequency solar radio bursts with LOFAR

Diana E. Morosan, Juska E. Räsänen, Anshu Kumari +9

The Sun is an active star that often produces numerous bursts of electromagnetic radiation at radio wavelengths. Low frequency radio bursts have recently been brought back to light…

Peculiar radioX-ray relationship in active stars

H. K. Vedantham, J. R. Callingham, T. W. Shimwell +5

The empirical relationship between the non-thermal 5GHz radio luminosity and the soft X-ray luminosity of active stellar coronae, canonically called the Güdel-Benz relationship (Gü…
