The Roles of Tidal Evolution and Evaporative Mass Loss in the Origin of CoRoT-7 b
, 2010 CoRoT-7 b is the first confirmed rocky exoplanet, but, with an orbital semi-major axis of 0.0172 AU, its origins may be unlike any rocky planet in our solar system.

KELT-1b: A Strongly Irradiated, Highly Inflated, Short Period, 27 Jupiter-mass Companion Transiting a mid-F Star [PDF]
, 2012 We present the discovery of KELT-1b, the first transiting low-mass companion from the wide-field Kilodegree Extremely Little Telescope-North (KELT-North) survey. The V=10.7 primary is a mildly evolved, solar-metallicity, mid-F star.

Effects of Hydrogen on Fe‐S Alloys and Their Implications for the Martian Core
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Meteorites suggest the Martian core comprises iron (Fe) or iron‐nickel (Fe‐Ni) alloy with sulfur (S) identified as the primary light element. The InSight data revealed a larger, less dense Martian core than previously estimated, indicating additional light elements.

Polar Neptunes Are Stable to Tides
The Astrophysical JournalThere is an intriguing and growing population of Neptune-sized planets with stellar obliquities near ∼90°. One previously proposed formation pathway is a disk-driven resonance, which can take place at the end stages of planet formation in a system ...

Evidence for enhanced chromospheric Ca II H & K emission in stars with close-in extrasolar planets
, 2012 The planet-star interaction is manifested in many ways. It was found out that a close-in exoplanet causes small but measurable variability in the cores of a few lines in the spectra of several stars which corresponds to the orbital period of the ...

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,

Orbital Decay of Hot Jupiters due to Weakly Nonlinear Tidal Dissipation
The Astrophysical Journal, 2023 We study tidal dissipation in hot Jupiter host stars due to the nonlinear damping of tidally driven g -modes, extending the calculations of Essick & Weinberg to a wide variety of stellar host types. This process causes the planet’s orbit to decay and has

Tidal Limits to Planetary Habitability
, 2009 The habitable zones of main sequence stars have traditionally been defined as the range of orbits that intercept the appropriate amount of stellar flux to permit surface water on a planet. Terrestrial exoplanets discovered to orbit M stars in these zones,

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution
AGU Advances, Volume 6, Issue 6, December 2025.Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...
