Mass accretion rate in the jet-driving symbiotic binary MWC 560
Zamanov, R. K.; Marchev, V. D.
We analyze photometric observations of the symbiotic star MWC 560 in B and V bands obtained during the period 1990-2023. We estimate the luminosity and the mass accretion rate of the hot component. We find that the luminosity varies in the range from 200 L⊙ to 3000 L⊙, corresponding to a mass accretion rate in the range 1 × 10−7 − 2 × 10−6 M⊙ yr−1…
Characterization of the Early Dynamics of Solar Coronal Bright Fronts
Stepanyuk, Oleg; Kozarev, Kamen; Nedal, Mohamed +2 more
We present a comprehensive characterization of 26 Coronal Mass Ejection (CME)-driven compressive waves known as Coronal Bright Fronts (CBFs) observed in the low solar corona between 2010 and 2017. These CBFs have been found to be associated with Solar Energetic Particle (SEP) events near Earth, indicating their importance in understanding space we…
Investigation of three events of solar parameters and Interplanetary Coronal Mass ejections during the maximum phase of solar cycle 24
Dhaiya, M. S.; Bidhu, S. S.; Sobia, A. Iren
This paper analyzes the Three events of Solar Parameters and Interplanetary Coronal Mass Ejections in the maximum phase of Solar Cycle 24 and focuses on the magnetic activity of interplanetary coronal mass ejection during the solar cycle 24. We investigate the magnetic field magnitude (B), Proton temperature (Tp), Proton density (Np). From this st…
Properties of Milky Way globular clusters associated with X-ray sources
Nedialkov, Petko; Botev, Svetoslav; Petrov, Georgi P.
The integral X-ray luminosities of 89 Milky Way Globular Clusters within 2 core radii rc have been estimated using the average X-ray fluxes of individual sources detected in the recent Chandra, XMM-Newton or Swift missions. The X-ray luminosity function is constructed and a limit luminosity LX([0.5-7] keV) = 1033.65
