Survival of habitable planets in unstable planetary systems [PDF]
, 2016 Many observed giant planets lie on eccentric orbits. Such orbits could be the result of strong scatterings with other giant planets. The same dynamical instability that produces giant planet scatterings can also alter the orbits of terrestrial planets ...

The fine structure constant and habitable planets [PDF]
Journal of Cosmology and Astroparticle Physics, 2016 We use the existence of habitable planets to impose anthropic requirements on the fine structure constant, α. To this effect, we present two considerations that restrict its value to be very near the one observed.

4. Building of a Habitable Planet [PDF]
, 2006 Except the old Jack Hills zircon crystals, it does not exit direct record of the first 500 Ma of the Earth history. Consequently, the succession of events that took place during this period is only indirectly known through geochemistry, comparison with other telluric planets, and numerical modelling. Just after planetary accretion several episodes were

No Snowball on Habitable Tidally Locked Planets [PDF]
The Astrophysical Journal, 2017 The TRAPPIST-1, Proxima Centauri, and LHS 1140 systems are the most exciting prospects for future follow-up observations of potentially inhabited planets.

Habitable planets around the star Gliese 581? [PDF]
, 2007 Radial velocity surveys are now able to detect terrestrial planets at habitable distance from M-type stars. Recently, two planets with minimum masses below 10 Earth masses were reported in a triple system around the M-type star Gliese 581.

FORMING HABITABLE PLANETS AROUND DWARF STARS: APPLICATION TO OGLE-06-109L [PDF]
, 2011 Dwarf stars are believed to have small protostar disk where planets may grow up. During the planet formation stage, embryos undergoing type I migration are expected to be stalled at inner edge of magnetic inactive disk ($a_{\rm crit} \sim 0.2-0.3 ~$AU ...

Water Planets in the Habitable Zone: Atmospheric Chemistry, Observable Features, and the case of Kepler-62e and -62f [PDF]
, 2013 Planets composed of large quantities of water that reside in the habitable zone are expected to have distinct geophysics and geochemistry of their surfaces and atmospheres.

Business Strategy and the Environment, Volume 32, Issue 1, Page 72-95, January 2023., 2023 Abstract Sustainable entrepreneurs operating in protected areas face distinctive barriers that place additional emphasis on the need to build legitimacy. To date, how they do this has not been entirely explored. This paper addresses this need through an exploratory study of sustainable entrepreneurs in a transnational protected area.
