A complex network approach to TESS light curves of Sct stars
E. Ziaali, S. de Franciscis, J. Pascual-Granado +4
By using the horizontal visibility algorithm, the TESS light curves of 69 delta Sct stars are mapped to undirected horizontal visibility graphs (HVGs), where the graph nodes repres…
Galaxy Morphological Classification with Zernike Moments and Machine Learning Approaches
Hamed Ghaderi, Nasibe Alipour, Hossein Safari
Classifying galaxies is an essential step for studying their structures and dynamics. Using GalaxyZoo2 (GZ2) fractions thresholds, we collect 545 and 11,735 samples in non-galaxy a…
Solar rotation and activity for cycle 24 from SDO/AIA observations
Zahra Shokri, Nasibe Alipour, Hossein Safari
The differential rotation plays a crucial role in the dynamics of the Sun. We study the solar rotation and its correlation with solar activity by applying a modified machine learni…
Asymmetry of the spectral lines of the coronal hole and quiet Sun in the transition region
Razieh Hosseini, Pradeep Kayshap, Nasibe Alipour +1
The asymmetry of line profiles, i.e., the secondary component, is crucial to understanding the energy release of coronal holes (CH), quiet sun (QS), and bright points (BPs). We inv…
Zernike moments description of solar and astronomical features: Python code
Hossein Safari, Nasibe Alipour, Hamed Ghaderi +1
Due to the massive increase in astronomical images (such as James Webb and Solar Dynamic Observatory), automatic image description is essential for solar and astronomical. Zernike…
Complex network view for Scuti stars
Elham Ziaali, Nasibe Alipour, Hossein Safari
Extraction of characteristics of the complex light curve of pulsating stars is essential for stellar physics. We investigate the complex network (natural and horizontal visibility…
Automatic detection of small-scale EUV brightenings observed by the Solar Orbiter/EUI
N. Alipour, H. Safari, C. Verbeeck +23
Context. Accurate detections of frequent small-scale extreme ultraviolet (EUV) brightenings are essential to the investigation of the physical processes heating the corona. Aims. W…
Synchronization of Small-scale Magnetic Features, Blinkers, and Coronal Bright Points
Zahra Shokri, Nasibe Alipour, Hossein Safari +4
We investigate the relationship between different transients such as blinkers detected in images taken at 304~Å, extreme ultraviolet coronal bright points (ECBPs) at 193~Å, X-ray c…
Temperature Analysis of Flaring (AR11283) and non-Flaring (AR12194) Coronal Loops
Narges Fathalian, Seyedeh Somayeh Hosseini Rad, Nasibeh Alipour +1
Here, we study the temperature structure of flaring and non-flaring coronal loops, using extracted loops from images taken in six extreme ultraviolet (EUV) channels recorded by Atm…
Evolution of circumbinary protoplanetary disks with photoevaporative winds driven by External Far Ultraviolet Radiation
Mohsen Shadmehri, S. M. Ghoreyshi, N. Alipour
Lifetimes of protoplanetary disks (PPDs) are believed to be severely constrained by material depleting mechanisms, including photoevaporative winds due to the host star radiation o…
Prediction of Solar Flares Using Unique Signatures of Magnetic Field Images
Abbas Raboonik, Hossein Safari, Nasibe Alipour +1
Prediction of solar flares is an important task in solar physics. The occurrence of solar flares is highly dependent on the structure and the topology of solar magnetic fields. A n…
Solar Mini-Dimming Kinematics and Their Positive Correlations with Coronal Mass Ejections and Prominence
Nasibe Alipour, Hossein Safari
Solar mini-dimmings can be detect in the Extreme Ultra-Violet coro- nal eruptions. Here, sequences of 171 A images taken by Solar Dynamic Observa- tory/Atmospheric Imaging Assembal…
An Automatic Method for Extreme-Ultraviolet Dimmings Associated with Small-Scale Eruption
N. Alipour, H. Safari, D. E. Innes
Small-scale extreme ultraviolet (EUV) dimming often surrounds sites of energy release in the quiet Sun. This paper describes a method for the automatic detection of these small-sca…
