Modelling the dynamics and boundary processes of Svalbard glaciers [PDF]

, 2014
The focus of this thesis is on improving our understanding of surface and basal processes in the context of glaciers in Svalbard. At the surface, interactions with the atmosphere and underlying snow determine the surface mass balance.

Coupling the Secular Dynamical and Atmospheric Evolution of Close-in Exoplanets

This thesis plunges into the enigmatic formation of the hot Neptune desert, a sparsely populated region of exoplanetary demographics, by exploring the processes that shape close-in exoplanets. Central to this inquiry is the interplay between atmospheric evaporation and orbital migration, two pivotal mechanisms governing the evolution of planetary ...

The EBLM project – XIII. The absolute dynamical masses of the circumbinary planet host TOI-1338/BEBOP-1, and applications to the study of exoplanet atmospheres

Monthly Notices of the Royal Astronomical Society
ABSTRACT High-contrast eclipsing binaries with low mass M-dwarf secondaries are precise benchmark stars to build empirical mass–radius relationships for fully convective low-mass ($\rm M_{\star } \lt 0.35\, M_{\odot }$) dwarf stars. The contributed light of the M-dwarf in such binaries is usually much less than one per cent at optical ...

Momentum Budget of the atmospheric boundary layer over the Greenland ice sheet and its surrounding seas [PDF]

, 2011
The atmospheric circulation patterns over the Greenland ice sheet and its surrounding seas are studied by explicitly calculating the momentum budget components, using data of a high‐resolution regional atmospheric climate model.

Reinterpreting the JWST Observations of 55 Cancri e with a Nongray General Circulation Model

The Astrophysical Journal
Recent observations of 55 Cancri e suggest an atmosphere rich in CO or CO _2 ; other observations indicate the planet’s eclipse depth is highly variable.

The Metallicity and Carbon-to-oxygen Ratio of the Ultrahot Jupiter WASP-76b from Gemini-S/IGRINS

The Astronomical Journal
Measurements of the carbon-to-oxygen (C/O) ratios of exoplanet atmospheres can reveal details about their formation and evolution. Recently, high-resolution cross-correlation analysis has emerged as a method of precisely constraining the C/O ratios of ...

Global Chemical Transport on Hot Jupiters: Insights from the 2D VULCAN Photochemical Model

The Astrophysical Journal
The atmospheric dynamics of tidally locked hot Jupiters is characterized by strong equatorial winds. Understanding the interaction between global circulation and chemistry is crucial in atmospheric studies and interpreting observations.
