Discovery and Characterization of Three New High-amplitude delta Scuti Stars from TESS Observations
Chenglong Lv, Ali Esamdin, J. Pascual-Granado +5
We report the discovery and detailed analysis of three new high-amplitude δ Scuti (HADS) stars, TIC 408074920, TIC 189714989, and TIC 34137913, identified from Transiting Exoplanet…
Gravitational perturbations of a regular T-duality inspired black hole: Quasinormal modes, excitation factors, and time-domain evolution
Bekir Can Lütfüoğlu, Mardon Abdullaev, Javlon Rayimbaev +2
We study axial gravitational perturbations of the neutral regular black hole generated by a non-local, T-duality-inspired zero-point length and the associated gravitational self-en…
Relationship of ICME Composition Signatures with Solar Activity during 2009-2025
Diyorbek Pulatov, Zavkiddin Mirtoshev, Mirabbos Mirkamalov
Coronal Mass Ejections (CMEs) are among the most energetic solar eruptions, expelling magnetized plasma from the corona into interplanetary space. Their interplanetary counterparts…
What Causes the Asymmetry of Conjugate Hard X-Ray Footpoints in Solar Flares?
Mirabbos Mirkamalov, Rui Liu, Runbin Luo +1
Hard X-ray (HXR) emission in solar flares critically diagnoses nonthermal electron acceleration, transport, and precipitation. Observations commonly show asymmetric HXR photon flux…
Eikonal Ringing, Shadows, Lensing, Grey-Body Factors, and Binding Energy of Asymptotically Flat Regular Black Holes in Phantom Dirac-Born-Infeld Gravity
Mardon Abdullaev, Gumisbek Allambergenov, Diyorbek Rashidov +2
We develop a geodesic-optics description of eikonal quasinormal ringing, blackhole shadows, strong lensing, grey-body factors (GBFs), and the binding energy of massive particles fo…
Observational Properties of Cephei Stars: 88 new samples discovered Based on TESS and Gaia Data
Xiang-dong Shi, Sheng-bang Qian, Li-ying Zhu +5
We present a systematic investigation of Cephei (BCEP) stars by integrating photometric data from the Transiting Exoplanet Survey Satellite (TESS) with astrometric parameters f…
