Mass Flow and Accretion through gaps in Accretion Discs [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We study the structure and dynamics of the gap created by a protoplanet in an accretion disc. The hydrodynamic equations for a flat, two-dimensional, non-selfgravitating protostellar accretion disc with an embedded, Jupiter sized protoplanet on a ...

High Density Reflection Spectroscopy – II. The density of the inner black hole accretion disc in AGN [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present a high density disc reflection spectral analysis of a sample of 17 Seyfert 1 galaxies to study the inner disc densities at different black hole mass scales and accretion rates.

Global 3D radiation magnetohydrodynamic simulations for FU Ori’s accretion disc and observational signatures of magnetic fields [PDF]
Monthly notices of the Royal Astronomical Society, 2019 FU Ori is the prototype of FU Orionis systems that are outbursting protoplanetary discs. Magnetic fields in FU Ori’s accretion discs have previously been detected using spectropolarimetry observations for Zeeman effects.

An ionized accretion disc wind in Hercules X-1 [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Hercules X-1 is one of the best-studied highly magnetized neutron star X-ray binaries with a wealth of archival data. We present the discovery of an ionized wind in its X-ray spectrum when the source is in the high state.

Misaligned accretion disc formation via Kozai–Lidov oscillations [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We investigate the formation and evolution of misaligned accretion discs around the secondary component of a binary through mass transfer driven by Kozai-Lidov oscillations of the circumprimary disc's eccentricity and inclination.

Symposium - International Astronomical Union, 2003 In this article we report the results of our numerical investigation of warped accretion discs in binary stellar systems. We perform complete 3-D hydrodynamic simulations of binary discs. The disc is rendered unstable to the warp mode under the action of the magnetic field of the companion star in the binary.

Intensity and Polarization of Radiation Emerging from Rotating Accretion Disc with Increasing Height
Universe, 2020 We consider the radiation emission in continuum and spectral lines from rotating accretion disc with the progressive increasing height. It is known that for the plane accretion disc with homogeneous atmosphere the wave electric field E is perpendicular ...

Erratum: Probing gas disc physics with LISA: simulations of an intermediate mass ratio inspiral in an accretion disc [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The coalescence of a compact object with a $10^{4}\hbox{--}10^{7}\, {\rm M_\odot }$ supermassive black hole (SMBH) produces mHz gravitational waves (GWs) detectable by the future Laser Interferometer Space Antenna (LISA).
