Habitable Zones & Global Climate: October 2018


We have investigated the thorium (Th) abundance in a sample of 53 thin disc solar twins covering a wide range of ages.

The Earth is more than a one Earth-mass, one Earth-radius, one Earth-density planet. It is the only known terrestrial planet to undergo plate tectonics, have continental crust and a strong geodynamo.

The word "HAZMAT" describes substances that pose a risk to the environment, or even to life itself. Imagine the term being applied to entire planets, where violent flares from the host star may make entire worlds uninhabitable by affecting their atmospheres.

An international team of scientists, including high performance computing (HPC) experts from the King Abdullah University for Science and Technology (KAUST), astronomers from the Paris Observatory and the National Astronomical Observatory of Japan (NAOJ), in collaboration with NVIDIA, is taking the search for habitable planets and observation of first epoch galaxies to the next level.

Planetary rotation rate has a significant effect on atmospheric circulation, where the strength of the Coriolis effect in part determines the efficiency of latitudinal heat transport, altering cloud distributions, surface temperatures, and precipitation patterns.

We present detections of methane in R of 1300, L band spectra of VHS 1256 b and PSO 318.5, two low gravity, red, late L dwarfs that share the same colors as the HR 8799 planets.
