Habitable Zones & Global Climate: March 2017

We analyze short cadence K2 light curve of the TRAPPIST-1 system. Fourier analysis of the data suggests Prot=3.295±0.003 days.

Many of the multi-planet systems discovered to date have been notable for their compactness, with neighbouring planets closer together than any in the Solar System.

It is widely believed that the carbonate-silicate cycle is the main agent to trigger deglaciations by CO2 greenhouse warming on Earth and on Earth-like planets when they get in frozen state.

What caused the largest glaciation event in Earth's history, known as 'snowball Earth'? Geologists and climate scientists have been searching for the answer for years but the root cause of the phenomenon remains elusive.
