Extrasolar Planets and Their Host Stars
, 2017 In order to understand the exoplanet, you need to understand its parent star. Astrophysical parameters of extrasolar planets are directly and indirectly dependent on the properties of their respective host stars.

Journal 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
, 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.

Microlensing Searches for Exoplanets [PDF]
Geosciences, 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.

Lactea: Web‐Based Spectrum‐Preserving Multi‐Resolution Visualization of the GAIA Star Catalog
Computer Graphics Forum, Volume 44, Issue 3, June 2025.Abstract The explosion of data in astronomy has resulted in an era of unprecedented opportunities for discovery. The GAIA mission's catalog, containing a large number of light sources (mostly stars) with several parameters such as sky position and proper motion, is playing a significant role in advancing astronomy research and has been crucial in ...

Transit Photometry as an Exoplanet Discovery Method
, 2018 Photometry with the transit method has arguably been the most successful exoplanet discovery method to date. A short overview about the rise of that method to its present status is given.

Geophysical 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 ...

Characterizing Exoplanet Habitability [PDF]
, 2017 A habitable exoplanet is a world that can maintain stable liquid water on its surface. Techniques and approaches to characterizing such worlds are essential, as performing a census of Earth-like planets that may or may not have life will inform our understanding of how frequently life originates and is sustained on worlds other than our own ...
