Zodiacal Exoplanets in Time (ZEIT). VI. A Three-planet System in the Hyades Cluster Including an Earth-sized Planet [PDF]
Astronomical Journal, 2017 Planets in young clusters are powerful probes of the evolution of planetary systems. Here we report the discovery of three planets transiting EPIC 247589423, a late-K dwarf in the Hyades (≃800 Myr) cluster, and robust detection limits for additional ...

Genesis of the Planet Earth [PDF]
International Letters of Chemistry, Physics and Astronomy, 2015 This article is based on the theory of vortex gravitation and physical abnormalities of the Earth - slowing its rotation. Defined orbital acceleration, weight, approach to the Sun and the age of our planet. Offered to justify the creation of planetary material in the center of the Earth torsion, and not as the accumulation of cosmic dust and meteorites

The Humpty Dumpty Effect on Planet Earth
Frontiers in Conservation Science, 2022 Humans have treated the earth harshly. Degradation of extant ecosystems leaves little chance that they might function as they have in the past. Putting back the pieces and restoring what once existed is no longer possible even with re-wildling—an effect ...

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
