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…
Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager
Vincent Van Eylen, Richard Massey, Saeeda Awan +167
Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…
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…
The Role of Drag and Gravity on Dust Concentration in a Gravitationally Unstable Disc
Sahl Rowther, Rebecca Nealon, Farzana Meru +5
We carry out three dimensional smoothed particle hydrodynamics simulations to study the role of gravitational and drag forces on the concentration of large dust grains (St > 1) in…
Formation of misaligned second-generation discs through flyby encounters
Jeremy L. Smallwood, Rebecca Nealon, Nicolás Cuello +2
Observations reveal protoplanetary discs being perturbed by flyby candidates. We simulate a scenario where an unbound perturber, i.e., a flyby, undergoes an inclined grazing encoun…
A remnant planetary core in the hot-Neptune desert
David J. Armstrong, Théo A. Lopez, Vardan Adibekyan +91
The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of plan…
