Long-term variability of low-mass X-ray binaries

open access: yesEPJ Web of Conferences, 2014
We consider modulations of mass captured by the compact object from the companion star’s stellar wind in Low Mass X-ray Binaries with late type giants. Based on 3D simulations with two different hydrodynamic codes used Lagrangian and Eulerian approaches –

The transiting dust clumps in the evolved disc of the Sun-like UXor RZ Psc [PDF]

open access: yesRoyal Society Open Science, 2017
RZ Psc is a young Sun-like star, long associated with the UXor class of variable stars, which is partially or wholly dimmed by dust clumps several times each year.

Magnetically warped discs in close binaries

open access: yes, 2002
We demonstrate that measurable vertical structure can be excited in the accretion disc of a close binary system by a dipolar magnetic field centred on the secondary star.

Dissipative advective accretion disc solutions with variable adiabatic index around black holes [PDF]

open access: yes, 2014
We investigated accretion on to black holes in presence of viscosity and cooling, by employing an equation of state with variable adiabatic index and multi-species fluid.

Naked cuticle is essential for Drosophila wing development beyond Wingless signaling

open access: yesFEBS Open Bio, EarlyView.
Naked cuticle (Nkd), a Wnt signaling inhibitor, assumes extensive roles in Drosophila wing development. Overexpressing Nkd causes smaller, crumpled wings, while also perturbing multiple signaling pathways and developmental genes. A specific region (R1S) is critical for Nkd's function as a signaling integrator, offering new insights for studying its ...

Propagating mass accretion rate fluctuations in X-ray binaries under the influence of viscous diffusion

open access: yes, 2017
Many statistical properties of X-ray aperiodic variability from accreting compact objects can be explained by the propagating fluctuations model applied to the accretion disc.

The Comptonization of accretion disc X-ray emission: consequences for X-ray reflection and the geometry of AGN coronae [PDF]

open access: yes, 2014
We consider the Comptonisation of the photons that make up the relativistically blurred reflection that is commonly detected from the accretion discs of AGN by the coronae of energetic particles believed to give rise to the powerful X-ray continua by the

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

open access: yesFEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

The formation of planets by disc fragmentation

open access: yesEPJ Web of Conferences, 2013
I discuss the role that disc fragmentation plays in the formation of gas giant and terrestrial planets, and how this relates to the formation of brown dwarfs and low-mass stars, and ultimately to the process of star formation.
