THE MAGNETIC FIELD IMPACT ON ACCRETION RATE IN A PROTOPLANETARY DISK

Odessa Astronomical Publications, 2012
Recent observations are the evidence of a large-scale magnetic field in discs around classical T Tauri stars. A model of the axisymmetric thin protoplanetary disk in a global magnetic field is considered.

The Efficiency of Mass Accretion and Disc Structure from the Stellar Wind Mass Transfer in Binary Systems

Universe
There have been many research works involving mass transfer in stellar binaries, all of which are limited to certain systems with specific binary parameters.

Is the disc thermal state controlling the Blandford & Znajek/Blandford & Payne jet dichotomy?

EPJ Web of Conferences, 2013
It is generally assumed that Blandford & Payne jets can carry a significant fraction of the accretion power released in the underlying disc. But this fraction actually strongly depends on the disc aspect ratio h/r, hence on the disc thermal properties ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Towards a global model for planet formation in layered MHD wind-driven discs

Astronomy & Astrophysics
Context. Planet formation is inherently linked to the evolution of the protoplanetary disc. Recent developments point towards the possibility that disc evolution results from magnetised winds, rather than turbulent viscosity.

Confrontation of the Magnetically Arrested Disc Scenario with Observations of FR II Sources

Frontiers in Astronomy and Space Sciences, 2017
The main aim of our work was to check whether powers of jets in FR II radio galaxies (RGs) and quasars (QSOs) can be reproduced by the Magnetically Arrested Disc (MAD) scenario.

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
