Variable opacity and accretion-column regimes of magnetized neutron stars

Galina Lipunova, Pavel Abolmasov

Radiation-supported accretion columns of magnetized neutron stars can operate in several distinct regimes. As the accretion rate increases, magnetospheric accretion may proceed thr…

Shock-free super-Eddington accretion onto magnetized neutron star

Galina Lipunova, Pavel Abolmasov

Strong magnetic fields allow accreting neutron stars to form magnetically controlled funnel flows. At sufficiently high accretion rates, such flows become radiation-pressure-suppor…

Fingerprints of thermal Comptonization in accreting neutron stars. Plasma-vacuum interplay in cyclotron lines and polarisation

E. Sokolova-Lapa, D. K. Maniadakis, J. J. R. Stierhof +11

X-ray emission from accreting, strongly magnetised neutron stars and its pulse-phase variability probe their magnetic-field geometry, spin orientation, and emission processes. Whet…

The low luminosity end of Galactic HMXBs with eROSITA: Establishing a luminosity floor for accreting BeXRBs

Aafia Zainab, Philipp Thalhammer, Nico Zalot +18

We present a first look at the Galactic population of heretofore known HMXBs as observed by SRG/eROSITA during its first four surveys. eROSITA's sensitivity of $\sim10^{-13}\,\math…

Real-time observations of the transition to the quiescent state in an accreting magnetised neutron star: No propeller required?

Sergey S. Tsygankov, Galina Lipunova, Valery F. Suleimanov +6

The final stages of outbursts in transient X-ray pulsars (XRPs), which are characterised by a significant decline in the mass accretion rate, provide valuable insight into the phys…

Disc accretion onto a binary black hole in a hierarchical triple system as an origin of the most luminous hyper-soft sources

Sergei B. Popov, Galina V. Lipunova

We propose that the recently discovered luminous hypersoft X-ray sources can be explained by accretion onto a binary black hole in a hierarchical triple system. For black hole mass…
