Gravitational Instabilities in Circumstellar Disks [PDF]
Annual Review of Astronomy and Astrophysics, 2016 Star and planet formation are the complex outcomes of gravitational collapse and angular momentum transport mediated by protostellar and protoplanetary disks. In this review, we focus on the role of gravitational instability in this process. We begin with a brief overview of the observational evidence for massive disks that might be subject to ...

Dust in circumstellar disks [PDF]
, 2006 This thesis presents observational and theoretical studies of the size and spatial distribution of dust particles in circumstellar disks. Using millimetre interferometric observations of optically thick disks around T Tauri stars, I provide conclusive evidence for the presence of millimetre- to centimetre-sized dust aggregates.

Tracing episodic accretion with NOEMA: FU Orionis-type stars and their millimeter environment [PDF]
EPJ Web of Conferences, 2022 The earliest phases of star formation are characterised by intense mass accretion from the circumstellar disk to the central star. One group of lowmass young stellar objects, FU Orionis-type stars (FUors) exhibit accretion rate peaks accompanied by ...

The Astrophysical Journal, 2023 The first step toward planet formation is grain growth from (sub)micrometer to millimeter/centimeter sizes. Grain growth has been reported not only in Class II protoplanetary disks but also in Class 0/I protostellar envelopes.

Dynamics of Circumstellar Disks [PDF]
The Astrophysical Journal, 1998 We present a series of 2-dimensional hydrodynamic simulations of massive disks around protostars. We simulate the same physical problem using both a `Piecewise Parabolic Method' (PPM) code and a `Smoothed Particle Hydrodynamic' (SPH) code, and analyze their differences.

Turbulence in circumstellar disks [PDF]
Astronomy & Astrophysics, 2004 We investigate the analogy between circumstellar disks and the Taylor-Couette flow. Using the Reynolds similarity principle, the analogy results in a number of parameter-free predictions about stability of the disks, and their turbulent transport properties, provided the disk structure is available.

The Apparent Absence of Forward Scattering in the HD 53143 Debris Disk
The Astrophysical Journal, 2023 HD 53143 is a mature Sun-like star and host to a broad disk of dusty debris, including a cold outer ring of planetesimals near 90 au. Unlike most other inclined debris disks imaged at visible wavelengths, the cold disk around HD 53143 appears as ...
