Exoplanet Occurrence Rate with Age for FGK Stars in Kepler
The Astronomical JournalWe measure the exoplanet occurrence rate as a function of isochrone and gyrochronology ages using confirmed and candidate planets identified in Q1–17 DR25 Kepler data. We employ Kepler's pipeline detection efficiency to correct for the expected number of

, 2013 The hundreds of exoplanets that have been discovered in the past two decades offer a new perspective on planetary structure. Instead of being the archetypal examples of planets, those of our Solar System are merely possible outcomes of planetary system ...

On the Measurement of Ocean Acidity With Ambient Sound
Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.Abstract The volume‐integrated pH of seawater can be determined from the frequency and depth dependence of wind‐generated ambient noise in the ocean. Over the 1–10 kHz frequency band, three main processes contribute to the acoustic attenuation in seawater: the chemical relaxation of boric acid and magnesium carbonate (<3 kHz, related to pH) and of ...

Friends Not Foes: Strong Correlation between Inner Super-Earths and Outer Gas Giants
The Astrophysical Journal LettersThe connection between outer gas giants and inner super-Earths reflects their formation and evolutionary histories. Past work exploring this link has suggested a tentative positive correlation between these two populations, but these studies have been ...

TOI-1695 b: A Water World Orbiting an Early-M Dwarf in the Planet Radius Valley
The Astronomical Journal, 2023 Characterizing the bulk compositions of transiting exoplanets within the M dwarf radius valley offers a unique means to establish whether the radius valley emerges from an atmospheric mass-loss process or is imprinted by planet formation itself.

Ancient Mars Climate With a Polar Ocean and Ice Sheet Dynamics
Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract In this article, we study the conditions required to maintain a stable ocean on Mars 3 Ga using a new suite of simulations. These simulations couple a 3D Global Climate Model with ocean dynamics and ice sheet flow. The model includes the main processes of the atmosphere/hydrosphere/cryosphere to investigate Mars' ancient climate.

The Astronomical Journal, 2023 X-ray through infrared spectral energy distributions (SEDs) are essential for understanding a star’s effect on exoplanet atmospheric composition and evolution. We present a catalog of panchromatic SEDs, hosted on the Barbara A. Mikulski Archive for Space

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract Thermal convective processes in the liquid cores of terrestrial planetary bodies with the capacity to generate magnetic dynamos may be better characterized by thermal conductivity estimates of core conditions. The composition of the core of asteroid 4 Vesta as determined by geochemical studies of HED meteorites is used as an analog for the ...
