Temperature of Solar Orbiter/EUI quiet Sun small scale brightenings: evidence for a cooler component
A. Dolliou, S. Parenti, F. Auchère +16
Context: On 2020 May 30, small and short-lived EUV brightenings were observed in the Quiet Sun (QS) during a four minutes sequence by EUI/HRIEUV on board Solar Orbiter. Their physi…
Empirical relations between the intensities of Lyman lines of H and He
M. Gordino, F. Auchère, J. -C. Vial +9
Empirical relations between major UV and extreme UV spectral lines are one of the inputs for models of chromospheric and coronal spectral radiances and irradiances. They are also n…
The role of asymmetries in coronal rain formation during thermal non-equilibrium cycles
Gabriel Pelouze, Frédéric Auchère, Karine Bocchialini +4
Context: Thermal non-equilibrium (TNE) produces several observables that can be used to constrain the spatial and temporal distribution of solar coronal heating. Its manifestations…
The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action
I. Zouganelis, A. De Groof, A. P. Walsh +182
Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand…
On the spectroscopic detection of periodic plasma flows in loops undergoing thermal non-equilibrium
Gabriel Pelouze, Frédéric Auchère, Karine Bocchialini +3
Context: Long-period intensity pulsations were recently detected in the EUV emission of coronal loops, and have been attributed to cycles of plasma evaporation and condensation dri…
The Solar Orbiter SPICE instrument -- An extreme UV imaging spectrometer
The SPICE Consortium, :, M. Anderson +88
The Spectral Imaging of the Coronal Environment (SPICE) instrument is a high-resolution imaging spectrometer operating at extreme ultraviolet (EUV) wavelengths. In this paper, we p…
Comprehensive Determination of the Hinode/EIS Roll Angle
Gabriel Pelouze, Frédéric Auchère, Karine Bocchialini +5
We present a new coalignment method for the EUV Imaging Spectrometer (EIS) on board the Hinode spacecraft. In addition to the pointing offset and spacecraft jitter, this method det…
Statistical Analysis of Solar Events Associated with Storm Sudden Commencements over One Year of Solar Maximum during Cycle 23: Propagation from the Sun to the Earth and Effects
K. Bocchialini, B. Grison, M. Menvielle +9
Taking the 32 storm sudden commencements (SSCs) listed by ISGI during 2002 as a starting point, we performed a multi-criterion analysis based on observations (propagation time, vel…
On the occurrence of thermal non-equilibrium in coronal loops
C. Froment, F. Auchère, Z. Mikić +5
Long-period EUV pulsations, recently discovered to be common in active regions, are understood to be the coronal manifestation of thermal non-equilibrium (TNE). The active regions…
On The Fourier And Wavelet Analysis Of Coronal Time Series
F. Auchère, C. Froment, K. Bocchialini +2
Using Fourier and wavelet analysis, we critically re-assess the significance of our detection of periodic pulsations in coronal loops. We show that the proper identification of the…
Long-period intensity pulsations in the solar corona during activity cycle 23
F. Auchère, K. Bocchialini, J. Solomon +1
We report on the detection (10 σ) of 917 events of long-period (3 to 16 hours) intensity pulsations in the 19.5 nm passband of the SOHO Extreme ultraviolet Imaging Telescope. The d…
Can the Differential Emission Measure constrain the timescale of energy deposition
Chloé Guennou, Frédéric Auchère, James A. Klimchuk +2
In this paper, the ability of the Hinode/EIS instrument to detect radiative signatures of coronal heating is investigated. Recent observational studies of AR cores suggest that bot…
Oscillatory motions observed in eruptive filaments
K. Bocchialini, F. Baudin, S. Koutchmy +2
Context: The origin of the variable component of the solar wind is of great intrinsic interest for heliophysics and space-weather, e.g. the initiation of coronal mass ejections, an…
