Hard X-Ray Emission from Partially Occulted Solar Flares: RHESSI Observations in Two Solar Cycles
Frederic Effenberger, Fatima Rubio da Costa, Mitsuo Oka +5
Flares close to the solar limb, where the footpoints are occulted, can reveal the spectrum and structure of the coronal loop-top source in X-rays. We aim at studying the properties…
Hard X-ray morphology of the X1.3 April 25, 2014 partially occulted limb solar flare
Frederic Effenberger, Fatima Rubio da Costa, Vahe Petrosian
At hard X-ray energies, the bright footpoint emission from solar flare loops often prevents a detailed analysis of the weaker loop-top source morphology due to the limited dynamic…
Data-driven Radiative Hydrodynamic Modeling of the 2014 March 29 X1.0 Solar Flare
Fatima Rubio da Costa, Lucia Kleint, Vahé Petrosian +2
Spectroscopic observations of solar flares provide critical diagnostics of the physical conditions in the flaring atmosphere. Some key features in observed spectra have not yet bee…
Fermi Large Area Telescope observations of high-energy gamma-ray emission from behind-the-limb solar flares
Melissa Pesce-Rollins, Nicola Omodei, Vahe' Petrosian +3
Fermi-LAT >30 MeV observations have increased the number of detected solar flares by almost a factor of 10 with respect to previous space observations. These sample both the impuls…
The role of filament activation in a solar eruption
Fatima Rubio da Costa, Francesca Zuccarello, Lyndsay Fletcher +2
Observations show that the mutual relationship between filament eruptions and solar flares cannot be described in terms of an unique scenario. In some cases, the eruption of a fila…
Solar Flare Chromospheric Line Emission: Comparison Between IBIS High-resolution Observations and Radiative Hydrodynamic Simulations
Fatima Rubio da Costa, Lucia Kleint, Vahé Petrosian +2
Solar flares involve impulsive energy release, which results in enhanced radiation over a broad spectral range and a wide range of heights. In particular, line emission from the ch…
