Surface Manifestation of Stochastically Excited Internal Gravity Waves

Daniel Lecoanet, Matteo Cantiello, Evan H. Anders +5

Recent photometric observations of massive stars show ubiquitous low-frequency "red-noise" variability, which has been interpreted as internal gravity waves (IGWs). Simulations of…

Turbulent Convection in Subglacial Lakes

Louis-Alexandre Couston

Subglacial lakes are isolated, cold-temperature and high-pressure water environments hidden under ice sheets, which might host extreme microorganisms. Here, we use two-dimensional…

Dynamic flows create potentially habitable conditions in Antarctic subglacial lakes

Louis-Alexandre Couston, Martin Siegert

Trapped beneath the Antarctic ice sheet lie over 400 subglacial lakes, which are considered to be extreme, isolated, yet viable habitats for microbial life. The physical conditions…

Aspect ratio affects iceberg melting

Eric W. Hester, Craig D. McConnochie, Claudia Cenedese +2

Iceberg meltwater is a critical freshwater flux from the cryosphere to the oceans. Global climate simulations therefore require simple and accurate parameterisations of iceberg mel…

The Science Case for a Titan Flagship-class Orbiter with Probes

Conor A. Nixon, James Abshire, Andrew Ashton +36

We outline a flagship-class mission concept focused on studying Titan as a global system, with particular emphasis on the polar regions. Investigating Titan from the unique standpo…

Improved phase-field models of melting and dissolution in multi-component flows

Eric W. Hester, Louis-Alexandre Couston, Benjamin Favier +2

We develop and analyse the first second-order phase-field model to combine melting and dissolution in multi-component flows. This provides a simple and accurate way to simulate cha…
