Accretion‐powered Stellar Winds. III. Spin‐Equilibrium Solutions [PDF]
The Astrophysical Journal, 2008 We compare the stellar wind torque calculated in a previous work (Paper II) to the spin-up and spin-down torques expected to arise from the magnetic interaction between a slowly rotating ($\sim 10$% of breakup) pre-main-sequence star and its accretion disk.

Unveiling extremely veiled T Tauri stars [PDF]
, 2008 Photospheric absorption lines in classical T Tauri stars (CTTS) are weak compared to normal stars. This so-called veiling is normally identified with an excess continuous emission formed in shock-heated gas at the stellar surface below the accretion ...

The Astrophysical Journal, 2022 We perform three-dimensional (3D) magnetohydrodynamic simulations of magnetospheric accretion in a T Tauri star to study the accretion and wind structures in the close vicinity of the star.

MAGNETICALLY CONTROLLED ACCRETION FLOWS ONTO YOUNG STELLAR OBJECTS [PDF]
The Astrophysical Journal, 2011 (abridged) Accretion from disks onto young stars is thought to follow magnetic field lines from the inner disk edge to the stellar surface. The accretion flow thus depends on the geometry of the magnetic field. This paper extends previous work by constructing a collection of orthogonal coordinate systems, including the corresponding differential ...

Observable Signatures of Classical T Tauri Stars Accreting in an Unstable Regime
EPJ Web of Conferences, 2014 We discuss key observational signatures of Classical T Tauri stars (CTTSs) accreting through Rayleigh-Taylor instability, which occurs at the interface between an accretion disk and a stellar magnetosphere.

First Magnetic Field Detection on a Class I Protostar [PDF]
, 2009 Strong stellar magnetic fields are believed to truncate the inner accretion disks around young stars, redirecting the accreting material to the high latitude regions of the stellar surface.

Planet population synthesis driven by pebble accretion in cluster environments
, 2017 The evolution of protoplanetary discs embedded in stellar clusters depends on the age and the stellar density in which they are embedded. Stellar clusters of young age and high stellar surface density destroy protoplanetary discs by external ...

The Rising Star-Formation Histories of Distant Galaxies and Implications for Gas Accretion with Time [PDF]
, 2010 Distant galaxies show correlations between their current star-formation rates (SFRs) and stellar masses, implying that their star-formation histories (SFHs) are highly similar.

Low-Rate Accretion onto Isolated Stellar-Mass Black Holes [PDF]
Astronomy & Astrophysics, 2005 Magnetic field behaviour in a spherically-symmetric accretion flow for parameters typical of single black holes in the Galaxy is discussed. It is shown that in the majority of Galaxy volume, accretion onto single stellar-mass black holes will be spherical and have a low accretion rate ($10^{-6} - 10^{-9}$ of the Eddington rate).
