Effects of cold electron emissions on thermal plasma measurements on board Solar Orbiter spacecraft
Kataria, D. O.; Hellinger, P.; Maksimovic, M. +6 more
Aims. Emissions of photo and secondary electrons influence thermal electron measurements on board spacecraft, typically below a threshold determined by the spacecraft's potential. We aim to examine and quantify this contamination of the observed low-energy electron fluxes. We seek to provide effective constraints for the correction methods used to…
A simplified approach for reproducing fully relativistic spectra in X-ray binary systems: Application to Cygnus X-1
Papavasileiou, Th. V.; Kosmas, O.; Kosmas, T. S.
Context. General relativistic effects are strong near the black hole of an X-ray binary and significantly impact the total energy released in the innermost accretion disk's region. The simple pseudo-Newtonian solution in the standard disk model cannot replenish for effects such as light-bending, gravitational redshift, and Doppler boost. These can…
