Remote Sensing, 2021 We analyzed the Corine Land Cover 2018 (CLC2018) dataset to reveal the correspondence between land cover categories of the CLC and the spectral information of Landsat-8, Sentinel-2 and PlanetScope images.

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 eccentricities.

PLANET-PLANET SCATTERING IN PLANETESIMAL DISKS [PDF]
The Astrophysical Journal, 2009 We study the final architecture of planetary systems that evolve under the combined effects of planet-planet and planetesimal scattering. Using N-body simulations we investigate the dynamics of marginally unstable systems of gas and ice giants both in isolation and when the planets form interior to a planetesimal belt.

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

Specific Analysis of Web Camera and High Resolution Planetary Imaging [PDF]
Journal of Astronomy and Space Sciences, 2006 Web camera is usually used for video communication between PC, it has small sensing area, cannot using long exposure application, so that is insufficient for astronomical application.

The Search for other Earths: limits on the giant planet orbits that allow habitable terrestrial planets to form [PDF]
Astrophys.J. 643 (2006) L131-L134, 2006 Gas giant planets are far easier than terrestrial planets to detect around other stars, and are thought to form much more quickly than terrestrial planets. Thus, in systems with giant planets, the late stages of terrestrial planet formation are strongly affected by the giant planets' dynamical presence. Observations of giant planet orbits may therefore

The Astrophysical Journal, 2014 Hot Jupiters formed through circularization of high-eccentricity orbits should be found at orbital separations $a$ exceeding $twice$ that of their Roche limit $a_{\rm R}$. Nevertheless, about a dozen giant planets have now been found well within this limit ($a_{\rm R}

Puzzling out the coexistence of terrestrial planets and giant exoplanets. The 2/1 resonant periodic orbits [PDF]
, 2018 Hundreds of giant planets have been discovered so far and the quest of exo-Earths in giant planet systems has become intriguing. In this work, we aim to address the question of the possible long-term coexistence of a terrestrial companion on an orbit ...
