Accretion disks in luminous young stellar objects [PDF]
The Astronomy and Astrophysics Review, 2015 An observational review is provided of the properties of accretion disks around young stars. It concerns the primordial disks of intermediate- and high-mass young stellar objects in embedded and optically revealed phases. The properties were derived from

High-energy Neutrinos from Stellar Explosions in Active Galactic Nuclei Accretion Disks [PDF]
Astrophysical Journal Letters, 2021 Some catastrophic stellar explosions, such as supernovae (SNe), compact binary coalescences, and microtidal disruption events, are believed to be embedded in the accretion disks of active galactic nuclei (AGNs).

How accretion of planet-forming disks influences stellar abundances
Astronomy and Astrophysics, 2023 Millimeter-sized dust grains experience radial velocities exceeding the gas velocities by orders of magnitude. The viscous evolution of the accretion disk adds disk material onto the central star’s convective envelope, influencing its elemental abundances, [X/H].

Three-Layered Atmospheric Structure in Accretion Disks Around Stellar-Mass Black Holes [PDF]
Science, 2000 Modeling of the x-ray spectra of the Galactic superluminal jet sources GRS 1915+105 and GRO J1655-40 reveals a three-layered atmospheric structure in the inner region of their accretion disks. Above the cold and optically thick disk with a temperature of

YOUNG STELLAR OBJECTS IN LYNDS 1641: DISKS, ACCRETION, AND STAR FORMATION HISTORY [PDF]
The Astrophysical Journal Supplement Series, 2013 We investigate the young stellar objects (YSOs) in the Lynds 1641 (L1641) cloud using multi-wavelength data including Spitzer, WISE, the Two Micron All Sky Survey, and XMM covering ∼1390 YSOs across a range of evolutionary stages.

Circumstellar Disk Accretion Across the Lagoon Nebula: The Influence of Environment and Stellar Mass
The Astronomical JournalPre-main-sequence disk accretion is pivotal for determining the final stellar properties and the early conditions for close-in planets. We aim to establish the impact of internal (stellar mass) and external (radiation field) parameters on the disk ...

THE DESTRUCTION OF THIN STELLAR DISKS VIA COSMOLOGICALLY COMMON SATELLITE ACCRETION EVENTS [PDF]
The Astrophysical Journal, 2008 Most Galaxy-sized systems (Mhost ≃ 1012 M☉) in the ΛCDM cosmology are expected to have interacted with at least one satellite with a total mass Msat ≃ 1011 M☉ ≃ 3Mdisk in the past 8 Gyr. Analytic and numerical investigations suggest that this is the most

ON THE ROLE OF DISKS IN THE FORMATION OF STELLAR SYSTEMS: A NUMERICAL PARAMETER STUDY OF RAPID ACCRETION [PDF]
The Astrophysical Journal, 2009 We study rapidly accreting, gravitationally unstable disks with a series of idealized global, numerical experiments using the code ORION. Our numerical parameter study focuses on protostellar disks, showing that one can predict disk behavior and the ...

Accretion-modified Stars in Accretion Disks of Active Galactic Nuclei: Gravitational-wave Bursts and Electromagnetic Counterparts from Merging Stellar Black Hole Binaries [PDF]
Astrophysical Journal Letters, 2021 The recent advanced LIGO/Virgo detections of gravitational waves (GWs) from stellar binary black hole (BBH) mergers, in particular GW190521, which is potentially associated with a quasar, have stimulated renewed interest in active galactic nuclei as ...
