Volcanism at Piton de la Fournaise as an Analog for Chloris Mons, Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Identifying and investigating terrestrial analogs for Venus volcanic activity is necessary to prepare for the planned upcoming missions to Venus. We propose volcanism at Piton de la Fournaise, a frequently active oceanic shield volcano, as an analog to volcanism at Chloris Mons, Venus.

On homogeneous statistical distributions exoplanets for their dynamic parameters

, 2009
Correct distributions of extrasolar systems for their orbital parameters (semi-major axes, period, eccentricity) and physical characteristics (mass, spectral type of parent star) are received. Orbital resonances in extrasolar systems are considered. It is shown, that the account of more thin effects, including with use of wavelet methods, in obviously ...

An Observational Diagnostic for Distinguishing between Clouds and Haze in Hot Exoplanet Atmospheres [PDF]

, 2017
The nature of aerosols in hot exoplanet atmospheres is one of the primary vexing questions facing the exoplanet field. The complex chemistry, multiple formation pathways, and lack of easily identifiable spectral features associated with aerosols make it ...

The Prevalence of Resonance Among Young, Close-in Planets

The Astronomical Journal
Multiple planets undergoing disk migration may be captured into a chain of mean-motion resonances with the innermost planet parked near the disk’s inner edge.

Impacts of Carbon Dioxide Deposition on Martian Near‐Surface Wave Activity

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract A prominent feature of Mars' winter atmosphere is near‐surface baroclinic wave activity. These waves exert strong control on dust storm variability and contribute to transport of heat, momentum, and dust. Using a suite of Mars general circulation model simulations, we investigate an underexplored connection between near‐surface wave activity ...

Investigating the Origins of Hot Neptunes from Radial Velocity Data

The Astronomical Journal
Hot Neptunes are extrasolar planets that are similar in size to Neptune in our solar system but are much closer to their host stars, completing an orbit in 10 days or less. The origin of hot Neptunes is not fully understood.

The Dynamics-Based Approach to Studying Terrestrial Exoplanets

, 2007
One of the great quests of astronomy is to obtain the spectrum of a terrestrial planet orbiting within the habitable zone of its star, and the dominant challenge in doing so is to isolate the light of the planet from that of the star. Dynamics-based methods separate these signals temporally, whereas imaging techniques do so spatially.

Ground-breaking Exoplanet Science with the ANDES spectrograph at the ELT [PDF]

, 2023
In the past decade the study of exoplanet atmospheres at high-spectral resolution, via transmission/emission spectroscopy and cross-correlation techniques for atomic/molecular mapping, has become a powerful and consolidated methodology.
