Evaluating the GeoSnap 13‐μ$$ \mu $$m cutoff HgCdTe detector for mid‐IR ground‐based astronomy
Astronomische Nachrichten, Volume 344, Issue 8-9, October-November 2023., 2023 Abstract New mid‐infrared HgCdTe (MCT) detector arrays developed in collaboration with Teledyne Imaging Sensors (TIS) have paved the way for improved 10‐μ$$ \mu $$m sensors for space‐ and ground‐based observatories. Building on the successful development of longwave HAWAII‐2RGs for space missions such as NEO Surveyor, we characterize the first 13‐μ ...

Journal of Geophysical Research: Planets, Volume 128, Issue 9, September 2023., 2023 Abstract To understand the evolution of the Moon, we numerically modeled mantle convection and magmatism in a two‐dimensional polar rectangular mantle. Magmatism occurs as an upward permeable flow of magma generated by decompression melting through the convecting matrix.

Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems
The Astronomical Journal, 2023 The geometries of near-resonant planetary systems offer a relatively pristine window into the initial conditions of exoplanet systems. Given that near-resonant systems have likely experienced minimal dynamical disruptions, the spin–orbit orientations of ...

Scientific novelty beyond the experiment
Microbial Biotechnology, Volume 16, Issue 6, Page 1131-1173, June 2023., 2023 Practical experiments drive important scientific discoveries in biology, but theory‐based research studies also contribute novel—sometimes paradigm‐changing—findings. Here, we appraise the roles of theory‐based approaches focusing on the experiment‐dominated wet‐biology research areas of microbiology. Theory‐based studies can transcend barriers imposed

The Astrophysical Journal, 2023 Protoplanets formed in a marginally gravitationally unstable (MGU) disk by either core accretion or disk instability will be subject to dynamical interactions with massive spiral arms, possibly resulting in inward or outward orbital migration, mergers ...

, 2021 Studies of planet migration derived from disc planet interactions began before the discovery of exoplanets. The potential importance of migration for determining orbital architectures being realised, the field received greater attention soon after the initial discoveries of exoplanets.

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 2, February 2023., 2023 Abstract Recent theoretical studies suggest that the physical and rheological mantle properties in massive rocky planets fall outside conventional behaviors inferred for mantle properties at the Earth's mantle pressures. The vacancy diffusion occurring at low pressures is assumed to be followed by interstitial diffusion above ∼0.1 TPa resulting in ...

Global Modeling of Ganymede's Surface Composition: Near‐IR Mapping From VLT/SPHERE
Journal of Geophysical Research: Planets, Volume 127, Issue 12, December 2022., 2022 Abstract We present maps of Ganymede's surface composition with almost complete longitude coverage, acquired using high spatial resolution near‐infrared (0.95–1.65 μm) observations from the ground‐based VLT/SPHERE instrument. Observed reflectance spectra were modeled using a Markov Chain Monte Carlo method to estimate abundances and associated ...

Chemistry and physics of dopants embedded in helium droplets
Mass Spectrometry Reviews, Volume 41, Issue 4, Page 529-567, July/August 2022., 2022 Abstract Helium droplets represent a cold inert matrix, free of walls with outstanding properties to grow complexes and clusters at conditions that are perfect to simulate cold and dense regions of the interstellar medium. At sub‐Kelvin temperatures, barrierless reactions triggered by radicals or ions have been observed and studied by optical ...

Confirming Resonance in Three Transiting Systems
The Astronomical Journal, 2023 Although resonant planets have orbital periods near commensurability, resonance is also dictated by other factors, such as the planets’ eccentricities and masses, and therefore must be confirmed through a study of the system’s dynamics.
