Magnetospheric accretion on the fully-convective classical T Tauri star DN Tau [PDF]

open access: yes, 2013
The MaPP project is supported by the funding agencies of CFHT and TBL (through the allocation of telescope time) and by INSU/CNRS in particular, as well as by the French ‘Agence Nationale pour la Recherche’ (ANR).

The Relationship between Mg ii Broad Emission and Quasar Inclination Angle

open access: yesFrontiers in Astronomy and Space Sciences, 2017
Several observed spectral properties of quasars are believed to be influenced by quasar orientation. In this investigation we examine the effect of orientation on the Mg ii line located at 2,798 Å in a sample of 36 radio-loud quasars, with orientation ...

Contributions of Organic and Mineral Matter to Vertical Accretion in Tidal Wetlands across a Chesapeake Bay Subestuary

open access: yesJournal of Marine Science and Engineering, 2021
Persistence of tidal wetlands under conditions of sea level rise depends on vertical accretion of organic and inorganic matter, which vary in their relative abundance across estuarine gradients.

Impacts of urbanization and tourism on the erosion and accretion of European, Asian and African coastal areas and possible solutions [PDF]

open access: yesUrbanism. Arhitectura. Constructii, 2020
Coastal areas are very important due to the ecosystem services provided to the inhabitants. However, these advantages have resulted into an increasing attraction, especially in the recent centuries.

Intermediate-Mass Black Holes: The Essential Population to Explore the Unified Model for Accretion and Ejection Processes

open access: yesGalaxies, 2023
We study radio and X-ray emissions from intermediate-mass black holes (IMBHs) and explore the unified model for accretion and ejection processes. The radio band survey of IMBH (candidate) hosted galaxies indicates that only a small fraction (∼0.6%) of ...

Modelling and observations of molecules in discs around young stars [PDF]

open access: yes, 2013
This thesis contains a study of molecules within circumstellar discs around young stars. Firstly, the chemistry of a disc around a young, Class 0 protostar is modelled.

TERRAIN TECTONICS OF THE CENTRAL ASIAN FOLDED BELT

open access: yesГеодинамика и тектонофизика, 2015
The terrain analysis concept envisages primarily a possibility of approximation of fragments / terrains of various geodynamic settings which belong to different plates. The terrain analysis can supplement the theory of plate tectonics in solving problems

The X-ray position and optical counterpart of the accretion-powered millisecond pulsar XTE J1814−338 [PDF]

open access: yes, 2005
We report the precise optical and X-ray localization of the 3.2 ms accretion-powered X-ray pulsar XTE J1814-338 with data from the Chandra X-Ray Observatory as well as optical observations conducted during the 2003 June discovery outburst.

Self-Similar Solution of Hot Accretion Flow with Anisotropic Pressure

open access: yesUniverse, 2019
For the accretion flow in extremely low-luminosity active galactic nuclei, such as our Galactic center (Sgr A*) and M 87, the collisional mean-free path of ions may be much larger than its gyroradius.
