Tilting Planets during Planet Scattering [PDF]

open access: yesThe Astrophysical Journal Letters, 2021
Abstract Observational constraints on planetary spin axis have recently become possible, and they have revealed a system that favors large spin-axis misalignment, low stellar spin–orbit misalignment, and high eccentricity. To explain the origin of such systems, we propose a mechanism that could tilt the planetary spin axis during planet ...

Stellar Flybys Interrupting Planet–Planet Scattering Generates Oort Planets [PDF]

open access: yesThe Astronomical Journal, 2019
Abstract Wide-orbit exoplanets are starting to be detected, and planetary formation models are under development to understand their properties. We propose a population of “Oort” planets around other stars, forming by means of a mechanism analogous to how the solar system’s Oort cloud of comets was populated.

Spin Dynamics of Extrasolar Giant Planets in Planet–Planet Scattering [PDF]

open access: yesThe Astrophysical Journal, 2021
Abstract Planet–planet scattering best explains the eccentricity distribution of extrasolar giant planets, and 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 two-planet systems.

Extrasolar planets [PDF]

open access: yesProceedings of the National Academy of Sciences, 2000
The first known extrasolar planet in orbit around a Sun-like star was discovered in 1995. This object, as well as over two dozen subsequently detected extrasolar planets, were all identified by observing periodic variations of the Doppler shift of light emitted by the stars to which they are bound.

Atmosphere loss in planet–planet collisions [PDF]

open access: yesMonthly 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.

Analysis of PlanetScope Dove Digital Surface Model Accuracy Using Geometrically Simulated Images

open access: yesRemote Sensing, 2023
Many objectives in geoscience and engineering require Earth surface elevations at greater temporospatial resolution and coverage than are currently available.

ANALYSIS OF THE BENEFITS OF CORPORATE SOCIAL RESPONSIBILITY THROUGH THE TRIPLE BOTTOM LINE APPROACH AT PT. TIRTA INVESTAMA INDONESIA [PDF]

open access: yesRussian Journal of Agricultural and Socio-Economic Sciences, 2019
The role of Corporate Social Responsibility (CSR) has become increasingly important in the current era of globalization. This was triggered by the ecosystem of company activities to create business operational sustainability amid the local community ...

Dynamic Retrieval of Olive Tree Properties Using Bayesian Model and Sentinel-2 Images

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The goal of this study is to provide a fine detection and monitoring of olive orchard trees over large areas to anticipate any damage. We developed an original method to assess the spatiotemporal dynamics of biophysical parameters in the olive orchards ...

Migrating Planets [PDF]

open access: yesScience, 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 eccentricities.
