Evidence for coherent spicule oscillations by correcting Hinode/SOT Ca II H in the southeast limb of the Sun

Alireza Ahangarzadeh Maralani, Ehsan Tavabi, Ali Ajabshirizadeh

Wave theories of heating the chromosphere, corona, and solar wind due to photospheric fluctuations are strengthened by the existence of observed wave coherency up to the transition…

Evidence for Energy Supply by Active Region Spicules to the Solar Atmosphere

S. Zeighami, A. R. Ahangarzadeh Maralani, E. Tavabi +1

We investigate the role of active region spicules in the mass balance of the solar wind and energy supply for heating the solar atmosphere. We use high cadence observations from th…

Spicules Intensity Oscillations in SOT/HINODE Observations

E. Tavabi, A. Ajabshirizadeh, A. R. Ahangarzadeh Maralani +1

Aims. We study the coherency of solar spicules intensity oscillations with increasing height above the solar limb in quiet Sun, active Sun and active region using observations from…

The Possibility of Kelvin-Helmholtz Instability in Solar Spicules

A. Ajabshirizadeh, H. Ebadi, R. E. Vekalati +1

Transversal oscillations of spicules axes may be related to the propagation of magnetohydrodynamic waves along them. These waves may become unstable and the instability can be of t…

Spectral atlases of the Sun from 3980 to 7100 Å at the center and at the limb

Hassan Fathivavsari, Ali Ajabshirizadeh, Serge Koutchmy

In this work, we present digital and graphical atlases of spectra of both the solar disk-center and of the limb near the Solar poles using data taken at the UTS-IAP & RIAAM (the Un…

Study of Solar Magnetic and Gravitational Energies Through the Virial Theorem

Elham Bazyar, Ali Ajabshirizadeh, Zahra Fazel +1

Virial theorem is important for understanding stellar structures. It produces an interesting connection between the magnetic energy and the gravitational one. Using the general for…
