Accretion Disks in the Sub-Stellar Realm: Properties and Evolution [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractIt is now well established that young brown dwarfs harbor accretion disks –and thus undergo a T Tauri phase– similar to their low-mass stellar counterparts. The supporting evidence includes infrared and millimeter observations of the dust component as well as optical and infrared spectra with signatures of gas accretion and outflow.

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

Stellar and Accretion Disk Parameters of the Close Binary HD 50526 [PDF]
The Astronomical Journal, 2021 Abstract We present a photometric and spectroscopic study of HD 50526, an ellipsoidal binary member of the group Double Periodic Variable stars. Performing data mining in photometric surveys and conducting new spectroscopic observations with several spectrographs during 2008–2015, we obtained orbital and stellar parameters of the system.

FORGE'd in FIRE: Resolving the End of Star Formation and Structure of AGN Accretion Disks from Cosmological Initial Conditions [PDF]
The Open Journal of Astrophysics, 2023 It has recently become possible to zoom-in from cosmological to sub-pc scales in galaxy simulations to follow accretion onto supermassive black holes (SMBHs). However, at some point the approximations used on ISM scales (e.g.

Neutrino Fast Flavor Conversions in Neutron-Star Postmerger Accretion Disks. [PDF]
Physical Review Letters, 2021 A compact accretion disk may be formed in the merger of two neutron stars or of a neutron star and a stellar-mass black hole. Outflows from such accretion disks have been identified as a major site of rapid neutron-capture (r-process) nucleosynthesis and

Accretion-modified Stars in Accretion Disks of Active Galactic Nuclei: Slowly Transient Appearance [PDF]
Astrophysical Journal Letters, 2021 Compact objects are expected to exist in the accretion disks of supermassive black holes (SMBHs) in active galactic nuclei (AGNs), and in the presence of such a dense environment (∼1014 cm−3), they will form a new kind of stellar population denoted as ...

Supercritical Accretion of Stellar-mass Compact Objects in Active Galactic Nuclei [PDF]
Astrophysical Journal, 2021 Accretion disks of active galactic nuclei (AGNs) have been proposed as promising sites for producing both (stellar-mass) compact object mergers and extreme mass ratio inspirals.

Accretion onto Stars in the Disks of Active Galactic Nuclei [PDF]
Astrophysical Journal, 2021 Disks of gas accreting onto supermassive black holes are thought to power active galactic nuclei (AGN). Stars may form in gravitationally unstable regions of these disks, or may be captured from nuclear star clusters. Because of the dense gas environment,

Can Stellar-mass Black Hole Growth Disrupt Disks of Active Galactic Nuclei? The Role of Mechanical Feedback [PDF]
Astrophysical Journal, 2021 Stellar-mass BHs (sBHs) are predicted to be embedded in active galactic nucleus (AGN) disks owing to gravitational drag and in situ star formation. However, we find that, due to a high gas density in an AGN disk environment, compact objects may rapidly ...
