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

The Hunt for Exomoons with Kepler (HEK): III. The First Search for an Exomoon around a Habitable-Zone Planet

, 2013
Kepler-22b is the first transiting planet to have been detected in the habitable-zone of its host star. At 2.4 Earth radii, Kepler-22b is too large to be considered an Earth-analog, but should the planet host a moon large enough to maintain an atmosphere,

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 ...

A super-Earth-sized planet orbiting in or near the habitable zone around Sun-like star

, 2013
We present the discovery of a super-earth-sized planet in or near the habitable zone of a sun-like star. The host is Kepler-69, a 13.7 mag G4V-type star.

Quantifiable impact: monitoring landscape restoration from space. A regreening case study in Tanzania

Frontiers in Environmental Science
The 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 ...

JARAK MINIMUM ORBIT DAN TUMBUKAN POPULASI ASTEROID DEKAT-BUMI DENGAN PLANET BUMI [PDF]

Wahana Fisika: Jurnal Penelitian Fisika dan Terapannya, 2020
Asteroid dekat-Bumi diketahui memiliki orbit yang kaotik akibat seringnya terjadi papasan dekat dengan planet-planet terestrial. Orbit yang kaotik dapat membuat populasi objek ini berakhir sebagai penumbuk matahari maupun planet-planet.

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Planet Hunters. VI: An Independent Characterization of KOI-351 and Several Long Period Planet Candidates from the Kepler Archival Data [PDF]

, 2014
We report the discovery of 14 new transiting planet candidates in the Kepler field from the Planet Hunters citizen science program. None of these candidates overlapped with Kepler Objects of Interest (KOIs) at the time of submission.
