A Microphysics Model of Multicomponent Venus' Clouds With a High‐Accuracy Condensation Scheme

open access: yesEarth and Space Science, Volume 12, Issue 6, June 2025.
Abstract Accurate modeling of the Venusian cloud structure remains challenging due to its complex microphysical properties. Condensation primarily determines the cloud particle size distribution within the various cloud layers. However, existing Venus microphysics models mainly use a full‐stationary bin scheme, which may be prone to numerical diffusion

DYNAMIC EVOLUTION EXOPLANET SYSTEMS, MOVING IN ORBITAL RESONANCES WITH THE ACCOUNT OF SECULAR PERTURBATION FROM N BODIES

open access: yesOdessa Astronomical Publications, 2017
Equations of exoplanet's motion connected with orbital Lindblad resonances with the account of secular terms caused by gravitational non-resonant perturbation are derived. Qualitative researches of orbital evolution modeling exoplanet systems are carried

Asteroseismology of Exoplanet Host Stars

open access: yes, 2015
Asteroseismology is among the most powerful observational tools to determine fundamental properties of stars. Space-based photometry has recently enabled the systematic detection of oscillations in exoplanet host stars, allowing a combination of ...

Multifluid Equations for MHD

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract A set of magnetohydrodynamic equations is developed for multiple ion species in the limit of small Larmor radius. The derivation proceeds to explicitly calculate the Lorentz force resulting from the small ion drift velocities. The net effect is that in this limit all the ions move perpendicular to the magnetic field with the same E×B $\mathbf ...

The Demographics Of Exoplanets

open access: yes, 2018
Bridge Talk. Part I: Making a Hot Jupiter; the planet that shouldn't be there (P. Figueira). Part II: The Grand Tack; Jupiter & Saturn's migration in the gas disk (A. Crida). Part III: The NICE model; global instability in the giant planets' architecture after dispersal of the gas disk.

L'ADIEU AU RÉFÉRENT [PDF]

open access: yesDiversitate si Identitate Culturala in Europa, 2016
Exoplanets, discovered by Mayor and Queloz, have changed our definition of the word planet. Nowadays, nobody can defin precisely this term. Study this exemple shows that the referential sense is neither in words, nor in the head, but in a linguistic use,

Inferring the eccentricity distribution

open access: yes, 2010
Standard maximum-likelihood estimators for binary-star and exoplanet eccentricities are biased high, in the sense that the estimated eccentricity tends to be larger than the true eccentricity.

Long‐Lasting Volcanism of the Moon Aided by the Switch in Dominant Mechanisms of Magma Ascent: Role of Localized Radioactive Enrichment in a Numerical Model of Magmatism and Mantle Convection

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Significant volcanic activity continued for billions of years since 3.5–4 Gyr ago in the Procellarum KREEP Terrane (PKT) of the Moon, but not so significant outside the PKT. To understand this volcanic history, we developed a 2‐D numerical model of magmatism and mantle convection; the effects of the PKT on lunar evolution are considered by ...

Microlensing Searches for Exoplanets [PDF]

open access: yesGeosciences, 2018
Gravitational microlensing finds planets through their gravitational influence on the light coming from a more distant background star. The presence of the planet is then inferred from the tell-tale brightness variations of the background star during the lensing event, even if no light is detectable from the planet or the host foreground star.
