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…
The Role of Fission in Neutron Star Mergers and its Impact on the r-Process Peaks
Marius Eichler, Almudena Arcones, Alexandra Kelic +10
Comparing observational abundance features with nucleosynthesis predictions of stellar evolution or explosion simulations can scrutinize two aspects: (a) the conditions in the astr…
Photon mean free paths, scattering, and ever-increasing telescope resolution
Philip Judge, Lucia Kleint, Han Uitenbroek +3
We revisit an old question: what are the effects of observing stratified atmospheres on scales below a photon mean free path? The mean free path of photons emerging from the solar…
On the Origin of a Sunquake during the 29 March 2014 X1 Flare
Philip G. Judge, Lucia Kleint, Alina Donea +2
Helioseismic data from the HMI instrument have revealed a sunquake associated with the X1 flare SOL2014-03-29T17:48 in active region NOAA 12017. We try to discover if acoustic-like…
Hydrogen Balmer Continuum in Solar Flares Detected by the Interface Region Imaging Spectrograph (IRIS)
Petr Heinzel, Lucia Kleint
We present a novel observation of the white-light flare (WLF) continuum, which was significantly enhanced during the X1 flare on March 29, 2014 (SOL2014-03-29T17:48). Data from the…
Observations of Subarcsecond Bright Dots in the Transition Region above Sunspots with the Interface Region Imaging Spectrograph
H. Tian, L. Kleint, H. Peter +5
Observations with the Interface Region Imaging Spectrograph (IRIS) have revealed numerous sub-arcsecond bright dots in the transition region above sunspots. These bright dots are s…
Objective Bayesian analysis of "on/off" measurements
Diego Casadei
In high-energy astrophysics, it is common practice to account for the background overlaid with the counts from the source of interest with the help of auxiliary measurements carrie…
Reference analysis of the signal + background model in counting experiments II. Approximate reference prior
Diego Casadei
The objective Bayesian treatment of a model representing two independent Poisson processes, labelled as "signal" and "background" and both contributing additively to the total numb…
Detection of supersonic downflows and associated heating events in the transition region above sunspots
L. Kleint, P. Antolin, H. Tian +18
IRIS data allow us to study the solar transition region (TR) with an unprecedented spatial resolution of 0.33 arcsec. On 2013 August 30, we observed bursts of high Doppler shifts s…
Where is the chromospheric response to conductive energy input from a hot pre-flare coronal loop?
Marina Battaglia, Lyndsay Fletcher, Paulo J. A. Simões
Before the onset of a flare is observed in hard X-rays there is often a prolonged pre-flare or pre-heating phase with no detectable hard X-ray emission but pronounced soft X-ray em…
Helioseismic and Magnetic Imager observations of linear polarization from a loop prominence system
Pascal Saint-Hilaire, Jesper Schou, Juan-Carlos Martínez Oliveros +4
White-light observations by the Solar Dynamics Observatory's Helioseismic and Magnetic Imager of a loop-prominence system occurring in the aftermath of an X-class flare on 2013 May…
Statistical Properties of Super-hot Solar Flares
Amir Caspi, Säm Krucker, R. P. Lin
We use RHESSI high-resolution imaging and spectroscopy observations from ~6 to 100 keV to determine the statistical relationships between measured parameters (temperature, emission…
