Frontiers in Environmental ScienceThe impact of ecosystem conservation and restoration activities are rarely monitored from a global, multidimensional and multivariable perspective. Here we present an approach to quantify the environmental impact of landscape restoration using long-term ...

GJ 357 d: Potentially Habitable World or Agent of Chaos?
The Astronomical Journal, 2023 Multiplanet systems provide important laboratories for exploring dynamical interactions within the range of known exoplanetary system architectures. One such system is GJ 357, consisting of a low-mass host star and three orbiting planets, the outermost ...

Survival Function Analysis of Planet Size Distribution with GAIA Data Release 2 Updates [PDF]
, 2018 Applying the survival function analysis to the planet radius distribution of the Kepler confirmed/candidate planets, we have identified two natural divisions of planet radius at 4 Earth radii and 10 Earth radii. These divisions place constraints on planet formation and interior structure model.

, 2013 We infer the period ($P$) and size ($R_p$) distribution of Kepler transiting planet candidates with $R_p\ge 1 R_{\rm Earth}$ and $P < 250$ days hosted by solar-type stars.

HUMANIZING THE EARTH AND A POSSIBLE STRATEGY TO PREVENT A POSSIBLE DISASTER [PDF]
Annals: Series on Military Sciences, 2013 Earth is both a planet, a resource and an effect. A planet on which life is possible and a resource resumed from a cosmic and geophysical effect that sustains life. At the same time, the earth - as the planet of people is becoming more and more a product

A Plateau in the Planet Population Below Twice the Size of Earth [PDF]
, 2013 We carry out an independent search of Kepler photometry for small transiting planets with sizes 0.5--8.0 times that of Earth and orbital periods between 5 and 50 days, with the goal of measuring the fraction of stars harboring such planets. We use a new transit search algorithm, TERRA, optimized to detect small planets.

Case Studies of Habitable Trojan Planets in the System of HD 23079
, 2011 We investigate the possibility of habitable Trojan planets in the HD 23079 star-planet system. This system consists of a solar-type star and a Jupiter-type planet, which orbits the star near the outer edge of the stellar habitable zone in an orbit of low

Observing Exoplanets with High Dispersion Coronagraphy. I. The scientific potential of current and next-generation large ground and space telescopes [PDF]
, 2017 Direct imaging of exoplanets presents a formidable technical challenge owing to the small angular separation and high contrast between exoplanets and their host stars.

10 years with planet Earth: the essence of primary school children's drawings [PDF]
Geoscience Communication, 2020 “10 years with planet Earth” is the title of the calendar created for primary schools, realized in 2016 by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), the Italian Institute of Geophysical Research.

Exotic Earths: Forming Habitable Worlds with Giant Planet Migration [PDF]
Science 313 (2006) 1413, 2006 Close-in giant planets (e.g. ``Hot Jupiters'') are thought to form far from their host stars and migrate inward, through the terrestrial planet zone, via torques with a massive gaseous disk. Here we simulate terrestrial planet growth during and after giant planet migration.
