Signatures of photospheric convection throughout the solar atmosphere: the EVE Sun-as-a-star mHz continuum
Hugh Hudson, Anne-Marie Broomhall, Lyndsay Fletcher +5
Convectively driven motions in the solar photosphere can generate broadband Doppler variability across the chromosphere, transition region and corona. Here we investigate this vari…
First time delay observation between two mid-infrared channels in solar flare footpoints
Miguel Rojas-Quesada, Lyndsay Fletcher, Hugh Hudson +2
The strong correlation between energy injection and mid-infrared (mid-IR) emission observed during solar flares can be used to probe energy deposition throughout the chromosphere,…
Analysis of Eruptive Prominence Plasma Parameters' Effects on the \ion{He}{2} 304~Å Line with Solar Orbiter EUI Observations
Yong Zhang, Nicolas Labrosse, Sargam M. Mulay
An observation of a large prominence on the solar limb took place on February 15, 2022, by the Extreme Ultraviolet Imager (EUI) on board Solar Orbiter. We aim to determine the rang…
Extremely energetic EUV late phase of a pair of C-class flares caused by a non-eruptive sigmoid
Ya Wang, Sargam M. Mulay, Lyndsay Fletcher
The EUV late phase is the second increase of the irradiance of the warm coronal lines during solar flares, and has a crucial impact on the Earth's ionosphere. In this paper, we rep…
Origin of Unusual Composition of 3He-Rich Solar Energetic Particles
R. Bucik, G. M. Mason, S. M. Mulay +3
We examine 3He-rich solar energetic particles (SEPs) detected on 2023 October 24-25 by Solar Orbiter at 0.47 au. The measurements revealed that heavy-ion enhancements increase irre…
Simultaneous Eruption and Shrinkage of Pre-existing Flare Loops during a Subsequent Solar Eruption
Huadong Chen, Lyndsay Fletcher, Guiping Zhou +6
We investigated two consecutive solar eruption events in the solar active region (AR) 12994 at the solar eastern limb on 2022 April 15. We found that the flare loops formed by the…
Enhanced three-minute oscillation above a sunspot during a solar flare
Ya Wang, Lyndsay Fletcher, Sargam Mulay +2
Three-minute oscillations are a common phenomenon in the solar chromosphere above a sunspot. Oscillations can be affected by the energy release process related to solar flares. In…
Behaviour of molecular hydrogen emission in three solar flares
Sargam M. Mulay, Lyndsay Fletcher, Hugh Hudson +1
We have systematically investigated ultraviolet (UV) emission from molecular hydrogen (H) using the Interface Region Imaging Spectrometer (IRIS), during three X-ray flares of…
Formation and Thermodynamic Evolution of plasmoids in active region jets
Sargam M. Mulay, Durgesh Tripathi, Helen Mason +2
We have carried out a comprehensive study of the temperature structure of plasmoids, which successively occurred in recurrent active region jets. The multithermal plasmoids were se…
Fast Prograde Coronal Flows in Solar Active Regions
Hugh S. Hudson, Sargam M. Mulay, Lyndsay Fletcher +6
We report the discovery and characterization of high-speed (>100 km/s) horizontal flows in solar active regions, making use of the Sun-as-a-star spectroscopy in the range 5-105 nm…
Thermodynamic evolution of a sigmoidal active region with associated flares
Sargam M. Mulay, Durgesh Tripathi, Helen Mason
Active regions often show S-shaped structures in the corona called sigmoids. These are highly sheared and twisted loops formed along the polarity inversion line. They are considere…
Evidence of chromospheric molecular hydrogen emission in a solar flare observed by the IRIS satellite
Sargam M. Mulay, Lyndsay Fletcher
We have carried out the first comprehensive investigation of enhanced line emission from molecular hydrogen, H at 1333.79 Å, observed at flare ribbons in SOL2014-04-18T13:03.…
Temperature in Solar Sources of 3He-rich Solar Energetic Particles and Relation to Ion Abundances
R. Bucik, S. M. Mulay, G. M. Mason +3
3He-rich solar energetic particles (SEPs) are believed to be accelerated in solar flares or jets by a mechanism that depends on the ion charge-to-mass (Q/M) ratio. It implies that…
Study of the spatial association between an active region jet and a nonthermal type~ radio burst
Sargam M. Mulay, Rohit Sharma, Gherardo Valori +4
We aim to investigate the spatial location of the source of an active region (AR) jet and its relation with associated nonthermal type~III radio emission. An emission measure (EM)…
Temperature and Density Structure of a Recurring Active Region Jet
Sargam M. Mulay, Giulio Del Zanna, Helen Mason
We present a study of a recurring jet observed on October 31, 2011 by SDO/AIA, Hinode/XRT and Hinode/EIS. We discuss the physical parameters of the jet such as density, differentia…
Slipping Magnetic Reconnection, Chromospheric Evaporation, Implosion, and Precursors in the 2014 September 10 X1.6-Class Solar Flare
Jaroslav Dudik, Vanessa Polito, Miho Janvier +7
We investigate the occurrence of slipping magnetic reconnection, chromospheric evaporation, and coronal loop dynamics in the 2014 September 10 X-class flare. The slipping reconnect…
Multiwavelength study of twenty jets emanating from the periphery of active regions
