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…

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…

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…
