Tracing episodic accretion with NOEMA: FU Orionis-type stars and their millimeter environment [PDF]

open access: yesEPJ 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 ...

Grain Growth and Dust Segregation Revealed by Multiwavelength Analysis of the Class I Protostellar Disk WL 17

open access: yesThe 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]

open access: yesThe 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.

Avalanches and the Distribution of Reconnection Events in Magnetized Circumstellar Disks

open access: yesThe Astrophysical Journal, 2023
Cosmic rays produced by young stellar objects can potentially alter the ionization structure, heating budget, chemical composition, and accretion activity in circumstellar disks.

The Apparent Absence of Forward Scattering in the HD 53143 Debris Disk

open access: yesThe 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 ...
