Tidal Heating of Exomoons in Resonance and Implications for Detection
The Astronomical Journal, 2023 The habitability of exoplanets can be strongly influenced by the presence of an exomoon, and in some cases the exomoon itself could be a possible place for life to develop.

The Astronomical Journal, 2023 The detection of satellites around extrasolar planets, so called exomoons, remains a largely unexplored territory. In this work, we study the potential of detecting these elusive objects from radial velocity monitoring of self-luminous, directly imaged ...

Radio-loud Exoplanet-exomoon Survey: GMRT Search for Electron Cyclotron Maser Emission
The Astronomical Journal, 2022 We conducted the first dedicated search for signatures of exoplanet–exomoon interactions using the Giant Metrewave Radio Telescope (GMRT) as part of the radio-loud exoplanet-exomoon survey.

Snowball Earth Initiation and the Thermodynamics of Sea Ice
Journal of Advances in Modeling Earth Systems, Volume 14, Issue 8, August 2022., 2022 Abstract Snowball Earth is a hypothesized state in the deep past of Earth in which the ocean was completely or nearly completely covered by sea ice, resulting from a runaway ice‐albedo feedback. Here, we address how the treatment of sea‐ice thermodynamics affects the initiation of a Snowball Earth in the global climate model ICON‐A run in an idealized ...

AGU Advances, Volume 3, Issue 1, February 2022., 2022 Abstract Volatile compositions of asteroids provide information on the Solar System history and the origins of Earth's volatiles. Visible to near‐infrared observations at wavelengths of <2.5 µm have suggested a genetic link between outer main belt asteroids located at 2.5–4 au and carbonaceous chondrite meteorites (CCs) that show isotopic similarities ...

Long‐Term Earth‐Moon Evolution With High‐Level Orbit and Ocean Tide Models
Journal of Geophysical Research: Planets, Volume 126, Issue 12, December 2021., 2021 Abstract Tides and Earth‐Moon system evolution are coupled over geological time. Tidal energy dissipation on Earth slows rotation rate, increases obliquity, lunar orbit semi‐major axis and eccentricity, and decreases lunar inclination. Tidal and core‐mantle boundary dissipation within the Moon decrease inclination, eccentricity and semi‐major axis ...

The Signal of Solar Storms Embedded in Cosmogenic Radionuclides: Detectability and Uncertainties
Journal of Geophysical Research: Space Physics, Volume 126, Issue 8, August 2021., 2021 Abstract The threat that solar storms pose to our ever‐modernizing society has gathered significant interest in the recent past. This is partly due to the discoveries of large peaks in the content of cosmogenic radionuclides such as radiocarbon (14C) in tree rings and beryllium‐10 (10Be) and chlorine‐36 (36Cl) in ice cores that were linked to extreme ...

The Astronomical Journal, 2023 Moons orbiting exoplanets (“exomoons”) may hold clues about planet formation, migration, and habitability. In this work, we investigate the plausibility of exomoons orbiting the temperate ( T _eq = 294 K) giant ( R = 9.2 R _⊕ ) planet HIP 41378 f, which ...

1I/‘Oumuamua as an N2 Ice Fragment of an exo‐Pluto Surface: I. Size and Compositional Constraints
Journal of Geophysical Research: Planets, Volume 126, Issue 5, May 2021., 2021 Abstract The origin of the interstellar object 1I/‘Oumuamua has defied explanation. We perform calculations of the non‐gravitational acceleration that would be experienced by bodies composed of a range of different ices and demonstrate that a body composed of N2 ice would satisfy the available constraints on the non‐gravitational acceleration, size ...
