Properties of Galaxies with Counter-rotating Stellar Disks in the MaNGA Survey
The Astrophysical JournalThe gas accretion process can fuel both star formation and black hole activity, playing a critical role in galaxy evolution. The counter-rotating structures are believed to originate from gas accretion, serving as an ideal laboratory to study its impact ...

Variabiity of young stellar objects: Accretion, disks, outflows, and magnetic activity [PDF]
Astronomische Nachrichten, 2015 AbstractVariability is a key characteristic of young stars. Two major origins may be distinguished: a scaled‐up version of the magnetic activity seen on main‐sequence stars and various processes related to circumstellar disks, accretion, and outflows.

Global bifurcations to subcritical magnetorotational dynamo action in Keplerian shear flow [PDF]
, 2013 Magnetorotational dynamo action in Keplerian shear flow is a three-dimensional, non-linear magnetohydrodynamic process whose study is relevant to the understanding of accretion processes and magnetic field generation in astrophysics.

Characterizing circumstellar disk around young stars [PDF]
, 2010 The circumstellar disks play a fundamental role in star and planet formation process. Studies on circumstellar disks are generally carried on following two viable approaches: "statistical" studies, where a large samples of sources are measured to ...

Wind accretion by a binary stellar system and disc formation [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 I calculate the specific angular momentum of mass accreted by a binary system embedded in the dense wind of a mass losing asymptotic giant branch star. The accretion flow is of the Bondi-Hoyle-Lyttleton type. For most of the relevant parameters space the flow is basically an isothermal high Mach number accretion flow. I find that when the orbital plane

Advanced Engineering Materials, EarlyView.Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...
