A Framework for Quantifying the Degeneracies of Exoplanet Interior Compositions
, 2010 Several transiting super-Earths are expected to be discovered in the coming few years. While tools to model the interior structure of transiting planets exist, inferences about the composition are fraught with ambiguities.

Out There No One Has a Right to Die
Bioethics, EarlyView.ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...

Formation of Ultra-short-period Planets in Hot Jupiter Systems: Application to WASP-47
The Astrophysical Journal LettersThe WASP-47 system is notable as the first known system hosting both inner and outer low-mass planetary companions around a hot Jupiter, with an ultra-short-period (USP) planet as the innermost planetary companion.

Impacting Atmospheres: How Late-stage Pollution Alters Exoplanet Composition
The Astrophysical JournalThe atmospheric composition of exoplanets is often considered as a probe of the planet’s formation conditions. How exactly the initial chemical memory may be altered from the birth to the final state of the planet, however, remains unknown.

The Architectural Design Rules of Solar Systems based on the New Perspective
, 2009 On the basis of the Lunar Laser Ranging Data released by NASA on the Silver Jubilee Celebration of Man Landing on Moon on 21st July 1969-1994, theoretical formulation of Earth-Moon tidal interaction was carried out and Planetary Satellite Dynamics was ...

The Not-so Dramatic Effect of Advective Flows on Gas Accretion
The Astrophysical JournalSuper-Earths and mini-Neptunes are the most common types of exoplanets discovered, yet the physics of their formation are still debated. Standard core accretion models in gas-rich environments find that typical mini-Neptune mass planets would blow up ...

TOI-1695 b: A Water World Orbiting an Early-M Dwarf in the Planet Radius Valley
The Astronomical Journal, 2023 Characterizing the bulk compositions of transiting exoplanets within the M dwarf radius valley offers a unique means to establish whether the radius valley emerges from an atmospheric mass-loss process or is imprinted by planet formation itself.

Pursuing the planet-debris disk connection: Analysis of upper limits from the Anglo-Australian Planet Search [PDF]
, 2015 Solid material in protoplanetary discs will suffer one of two fates after the epoch of planet formation; either being bound up into planetary bodies, or remaining in smaller planetesimals to be ground into dust.

Friends Not Foes: Strong Correlation between Inner Super-Earths and Outer Gas Giants
The Astrophysical Journal LettersThe connection between outer gas giants and inner super-Earths reflects their formation and evolutionary histories. Past work exploring this link has suggested a tentative positive correlation between these two populations, but these studies have been ...
