Evolution of the Global Temperature Structure of the Solar Corona During the Minimum between Solar Cycles 23 and 24
(Iop Publishing Ltd, 2013-07-19)
The combination of Differential Emission Measure Tomography (DEMT) with extrapolation of the photospheric magnetic field allows determinatio/n of the electron density and electron temperature along individual magnetic field ...
Parallel evolution of quasi-separatrix layers and active region upflows
(Iop Publishing, 2015-08-10)
Persistent plasma upflows were observed with Hinode?s EUV Imaging Spectrometer (EIS) at the edges of active region (AR) 10978 as it crossed the solar disk. We analyze the evolution of the photospheric magnetic and velocity ...
Temporal evolution of fractality in the Earth’smagnetosphere and the solar photosphere
(American Geophysical Union, 2014)
The study of complexity in two aspects of the magnetic activity in the Sun-Earth system is
presented. We compare the temporal evolution of the magnetic fluctuations in the Earth’s magnetosphere
and the spatial distribution ...
Detection of spatially structured scattering polarization of Sr i 4607.3 Å with the Fast Solar Polarimeter
(EDP Sciences, 2018-11)
Context. Scattering polarization in the Sr I 4607.3 Å line observed with high resolution is an important diagnostic of the Sun's atmosphere and magnetism at small spatial scales. Investigating the scattering polarization ...
Evolution of small-scale magnetic elements in the vicinity of granular-size swirl convective motions
(Springer, 2015-01)
Advances in solar instrumentation have led to widespread use of time series to study the dynamics of solar features, especially at small spatial scales and at very fast cadences. Physical processes at such scales are ...
Magnetic activity in the photosphere of CoRoT-Exo-2a: Active longitudes and short-term spot cycle in a young Sun-like star
(Astronomy & Astrophysics, 2008)
Topological Analysis of Emerging Bipole Clusters Producing Violent Solar Events
(Springer, 2014-06)
During the rising phase of Solar Cycle 24 tremendous activity occurred on the Sun with fast and compact emergence of magnetic flux leading to bursts of flares (C to M and even X-class). We investigate the violent events ...

Evolution and dynamic properties of photospheric plasma in solar active regions
(2017-02)
Abstract. This work has been done for the initiation of the author into the field of solar physics. The work is divided in two main blocks. The first part gives an overview of topics in solar physics taking a journey ...
