Spin Dynamics of Extrasolar Giant Planets in Planet-Planet Scattering [PDF]
The Astrophysical Journal, 2021 Planet-planet scattering best explains the eccentricity distribution of extrasolar giant planets. Past literature showed that the orbits of planets evolve due to planet-planet scattering. This work studies the spin evolution of planets in planet-planet scattering in 2-planet systems. Spin can evolve dramatically due to spin-orbit coupling made possible

A New Family of Planets ? "Ocean Planets" [PDF]
Icarus, 2003 A new family of planets is considered which is between rochy terrestrial planets and gaseous giant ones: "Ocean-Planets". We present the possible formation, composition and internal models of these putative planets, including that of their ocean, as well

Science, 1998 A planet orbiting in a disk of planetesimals can experience an instability in which it migrates to smaller orbital radii. Resonant interactions between the planet and planetesimals remove angular momentum from the planetesimals, increasing their ...

Origins of Eccentric Extrasolar Planets: Testing the Planet-Planet Scattering Model [PDF]
Astrophys.J.686:621-636,2008, 2007 (Abridged) In planetary systems with two or more giant planets, dynamical instabilities can lead to collisions or ejections through strong planet--planet scattering. Previous studies for simple initial configurations with two equal-mass planets revealed some discrepancies between the results of numerical simulations and the observed orbital elements of

Free-floating Planets, Survivor Planets, Captured Planets, and Binary Planets from Stellar Flybys
The Astrophysical JournalIn star clusters, close stellar encounters can strongly impact the architecture of a planetary system or even destroy it. We present a systematic study of the effects of stellar flybys on two-planet systems.

Atmosphere loss in planet–planet collisions [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Many of the planets discovered by the Kepler satellite are close orbiting super-Earths or mini-Neptunes. Such objects exhibit a wide spread of densities for similar masses. One possible explanation for this density spread is giant collisions stripping planets of their atmospheres.

A transient inflammatory response contributes to oxaliplatin neurotoxicity in mice
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1985-1998, December 2022., 2022 Abstract Objectives Peripheral neuropathy is a relevant dose‐limiting adverse event that can affect up to 90% of oncologic patients with colorectal cancer receiving oxaliplatin treatment. The severity of neurotoxicity often leads to dose reduction or even premature cessation of chemotherapy.

Scientific American, 2006 A planet is an end product of disk accretion around a primary star or substar. I quantify this definition by the degree to which a body dominates the other masses that share its orbital zone. Theoretical and observational measures of dynamical dominance reveal a gap of four to five orders of magnitude separating the eight planets of our solar system ...

Two Distinct Magma Storage Regions at Ambrym Volcano Detected by Satellite Geodesy
Geophysical Research Letters, 2023 The flux of eruptible magma into a magmatic plumbing system influences eruption size and timing. If magma transfer is possible between two hydraulically‐connected magma lenses, system destabilization can tap a larger magma volume than stored in any one ...
