Oxidation of the Interiors of Carbide Exoplanets

open access: yesThe Planetary Science Journal, 2020
Astrophysical measurements have shown that some stars have sufficiently high carbon-to-oxygen ratios such that the planets they host would be mainly composed of carbides instead of silicates.

Efficient Geometric Probabilities of Multi-Transiting Exoplanetary Systems from CORBITS [PDF]

open access: yes, 2016
NASA's Kepler Space Telescope has successfully discovered thousands of exoplanet candidates using the transit method, including hundreds of stars with multiple transiting planets.

Evolutionary and functional relationships between plant and microbial C1 metabolism in terrestrial ecosystems

open access: yesNew Phytologist, Volume 248, Issue 3, Page 1132-1153, November 2025.
Summary One‐carbon (C1) metabolism, centered on the universal methyl donor S‐adenosyl methionine (SAM), plays critical roles in biosynthesis, redox regulation, and stress responses across plants and microbes. A recently proposed photosynthetic C1 pathway links SAM methyl groups directly to RuBisCO‐mediated CO2 assimilation and integrates with nitrogen ...

Variability of Known Exoplanet Host Stars Observed by TESS

open access: yesThe Astronomical Journal, 2023
Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of planetary properties, as well as contributing to our overall understanding ...

Ages and fundamental properties of Kepler exoplanet host stars from asteroseismology

open access: yes, 2015
We present a study of 33 {\it Kepler} planet-candidate host stars for which asteroseismic observations have sufficiently high signal-to-noise ratio to allow extraction of individual pulsation frequencies.

Physical constraints for the evolution of life on exoplanets

open access: yes, 2018
Recently, many Earth-sized planets have been discovered around stars other than the Sun that might possess appropriate conditions for life. The development of theoretical methods for assessing the putative habitability of these worlds is of paramount importance, since it serves the dual purpose of identifying and quantifying what types of biosignatures

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK

open access: yesJournal of Research in Science Teaching, Volume 62, Issue 8, Page 1902-1922, October 2025.
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

Exploring Warm Jupiter Migration Pathways with Eccentricities. I. Catalog of Uniform Keplerian Fits to Radial Velocities of 200 Warm Jupiters

open access: yesThe Astrophysical Journal Supplement Series
Giant planets are expected to predominantly form beyond the water-ice line and occasionally undergo inward migration. Unlike hot Jupiters, which can result from high-eccentricity tidal migration, warm Jupiters between 0.1 and 1 au (≈10–365 days) are in ...
