Probing the magnetospheric accretion region of the young pre-transitional disk system DoAr 44 using VLTI/GRAVITY
(EDP Sciences, 2020)
Context. Young stellar objects are thought to accrete material from their circumstellar disks through their strong stellar magnetospheres.
Aims. We aim to directly probe the magnetospheric accretion region on a scale ...
MULTILINE DOPPLER IMAGING OF MR SER IN HIGH STATE
(IOP PUBLISHING LTD, 2009)
Doppler images in Balmer, He I, He II and C II lines, and simultaneous I-band photometry of the polar MR Ser are presented and analyzed. The Balmer and Helium Doppler tomograms, of this bright polar at high mass transfer ...
A tree code for planetesimal dynamics: Comparison with a hybrid direct code
(Wiley Blackwell Publishing, Inc, 2003-12)
We present a tree code for simulations of collisional systems dominated by a central mass. We describe the implementation of the code and the results of some test runs with which the performance of the code was tested. A ...
Accretion disks around black holes in scalar-tensor-vector gravity
(American Physical Society, 2017-05)
Scalar-tensor-vector gravity (STVG) is an alternative theory of gravitation that has successfully explained the rotation curves of nearby galaxies, the dynamics of galactic clusters, and cosmological data without dark ...
Precession of neutrino-cooled accretion disks in gamma-ray burst engines
(EDP Sciences, 2006-07)
Aims. We study the precession of accretion disks in the context of gamma-ray burst inner engines. Methods. With an accretion disk model that allows for neutrino cooling, we evaluate the possible periods of disk precession ...
Outflow-confined H II regions. I. First signposts of massive star formation
(IOP PUBLISHING, 2016)
We present an evolutionary sequence of models of the photoionized disk-wind outflow around forming massive stars based on the Core Accretion model. The outflow is expected to be the first structure to be ionized by the ...
Precession and accretion in circumbinary discs: the case of HD 104237
(Royal Astronomical Society, 2015)
We present the results of smoothed particle hydrodynamics (SPH) simulations of the disc
around the young, eccentric stellar binary HD 104237. We find that the binary clears out a
large cavity in the disc, driving a ...
Swift J1357.2-0933: a massive black hole in the Galactic thick disc
(OXFORD UNIV PRESS, 2015)
Swift J1357.2-0933 is one of the shortest orbital period black hole X-ray transients. It exhibited deep optical dips together with an extremely broad Ha line during outburst. We present 10.4-m Gran Telescopio Canarias (GTC) ...
