A metallicity sweet spot for disc fragmentation and planet formation

Ethan J. Carter, Dimitris Stamatellos, George Blaylock-Squibbs +2

Fragmentation of gravitationally unstable discs offers an alternate formation mechanism for gas giant planets and brown dwarfs on wide orbits. Metallicity plays a key role in disc…

Revisiting gravitational instability in protostellar discs with improved radiative cooling models

Alison K. Young, Ken Rice, Richard Booth +1

Young discs are expected to be significantly more massive than those observed at Myr and it is at this earliest stage that planet formation likely begins. Such massive discs m…

High-resolution simulations of disc tearing in the GW Orionis triple system

Alison K. Young

The disc around the pre-main-sequence triple star system GW Orionis is known from observations to be warped and broken. Theoretical modelling has produced conflicting results regar…

Dust density enhancements and the direct formation of planetary cores in gravitationally unstable discs

Ken Rice, Hans Baehr, Alison K Young +5

Planet formation via core accretion involves the growth of solids that can accumulate to form planetary cores. There are a number of barriers to the collisional growth of solids in…

Introducing two improved methods for approximating radiative cooling in hydrodynamical simulations of accretion discs

Alison K. Young, Maggie Celeste, Richard A. Booth +4

The evolution of many astrophysical systems depends strongly on the balance between heating and cooling, in particular star formation in giant molecular clouds and the evolution of…

On the conditions for warping and breaking protoplanetary discs

Alison K. Young, Struan Stevenson, C. J. Nixon +1

Recent observations demonstrate that misalignments and other out-of-plane structures are common in protoplanetary discs. Many of these have been linked to a central host binary wit…

Characteristics of small protoplanetary disc warps in kinematic observations

Alison K. Young, Richard Alexander, Giovanni Rosotti +1

Many circumstellar discs appear to have misaligned central regions that give rise to shadows seen in scattered light observations. Small warps ( misalignment) are probab…

Chemical signatures of a warped protoplanetary disc

Alison K. Young, Richard Alexander, Catherine Walsh +3

Circumstellar discs may become warped or broken into distinct planes if there is a stellar or planetary companion with an orbit that is misaligned with respect to the disc. There i…

A triple star system with a misaligned and warped circumstellar disk shaped by disk tearing

Stefan Kraus, Alexander Kreplin, Alison K. Young +29

Young stars are surrounded by a circumstellar disk of gas and dust, within which planet formation can occur. Gravitational forces in multiple star systems can disrupt the disk. The…

Synthetic molecular line observations of the first hydrostatic core from chemical calculations

Alison K. Young, Matthew R. Bate, Tim J. Harries +1

The first stable object to develop in the low-mass star formation process has long been predicted to be the first hydrostatic core (FHSC). Despite much effort, it has still yet to…

Dust-trapping vortices and a potentially planet-triggered spiral wake in the pre-transitional disk of V1247 Orionis

Stefan Kraus, Alexander Kreplin, Misato Fukagawa +8

The radial drift problem constitutes one of the most fundamental problems in planet formation theory, as it predicts particles to drift into the star before they are able to grow t…

What can the SEDs of first hydrostatic core candidates reveal about their nature?

Alison K. Young, Matthew R. Bate, Chris F. Mowat +2

The first hydrostatic core (FHSC) is the first stable object to form in simulations of star formation. This stage has yet to be observed definitively, although several candidate FH…
