With JWST, we are directly imaging cold (~200-300K), solar-age giant exoplanets for the first time.
In this study, we aim to constrain the atmospheric composition of GJ 1214 b using all available transits observed with the upgraded CRIRES+ spectrograph at the VLT by searching for […]
The current census of planetary systems displays a wide range of architectures. Extending earlier work, this paper investigates the correlation between our classification framework for these architectures and host stellar […]
With the operation of JWST, atmospheric characterization has now extended to low-mass exoplanets.
The giant planet-metallicity correlation revealed that planetary formation depends on the stellar properties. There is growing evidence that it is also valid for smaller hot planets, but it is not […]
Despite being only the 19th most abundant element in the interstellar medium, chlorine’s reactivity and volatility give rise to a unique interstellar chemistry, favouring the formation of several chlorine-bearing hydrides.
The well-known correlation between stellar metallicity and planet occurrence is strongest for giant planets, but weaker for smaller planets, suggesting that detailed elemental patterns beyond [Fe/H] may be relevant.
Clues about how galaxies like our Milky Way form and evolve and why their stars show surprising chemical patterns have been revealed by a new study.
Sub-Neptunes represent the largest exoplanet demographic, yet their bulk compositions remain poorly understood.
![(a) Normalized age distributions p(τ | [Fe/H]) for single stars, binned in [Fe/H] and smoothed using Gaussian filtering. Each vertical slice is normalized by its peak value. The blue line marks the peak age in each bin. Colored points show planet-hosting stars, classified by guiding-center radius Rg: inner (Rg < 7.2 kpc), local (7.2 ≤ Rg ≤ 9.2 kpc), and outer (Rg > 9.2 kpc). (b) Same as (a), but for [α/Fe] instead of [Fe/H]. -- astro-ph.SR](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/10/Insights-into-Planet-Formation-from.png?resize=1200%2C714&ssl=1)
How planetary systems form and evolve is a key question in astronomy. Revealing how host star properties, such as elemental abundances, age, and mass, differ from those of non-host stars, […]
