The Demographics of Terrestrial Planets in the Venus Zone
The Astronomical Journal, 2023 Understanding the physical characteristics of Venus, including its atmosphere, interior, and its evolutionary pathway with respect to Earth, remains a vital component for terrestrial planet evolution models and the emergence and/or decline of planetary ...

The multiplicity of exoplanet host stars [PDF]
, 2008 Aims. We present new results from our ongoing multiplicity study of exoplanet host stars, carried out with SofI/NTT. We provide the most recent list of confirmed binary and triple star systems that harbor exoplanets. Methods.

Alkaline exospheres of exoplanet systems: evaporative transmission spectra [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Hydrostatic equilibrium is an excellent approximation for the dense layers of planetary atmospheres, where it has been canonically used to interpret transmission spectra of exoplanets. Here, we exploit the ability of high-resolution spectrographs to probe tenuous layers of sodium and potassium gas due to their formidable ...

The effect of galactic kinematics on exoplanet demographics and habitability [PDF]
, 2023 : Recent studies show that galactic kinematics could affect planetary system architectures [1,2]. Planetary systems that reside in phase-space overdensities, corresponding to ripples and streams in the galactic disk, have been shown to have lower ...

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.
