Extrasolar Planets: July 2017


In order to understand the exoplanet, you need to understand its parent star. Astrophysical parameters of extrasolar planets are directly and indirectly dependent on the properties of their respective host stars.

TRAPPIST-1 planets are invaluable for the study of comparative planetary science outside our Solar System and possibly habitability.

As evident from the nearby examples of Proxima Centauri and TRAPPIST-1, Earth-sized planets in the habitable zone of low-mass stars are common. Here, we focus on such planetary systems and argue that their (oceanic) tides could be more prominent due to stronger tidal forces.

The National Science Foundation's Arecibo Observatory and the Planetary Habitability Laboratory of the University of Puerto Rico at Arecibo joined the Red Dots project in the search for new planets around our nearest stars.

Two fundamental problems for extraterrestrial intelligences (ETIs) attempting to establish interstellar communication are timing and energy consumption.

The discovery of exoplanets has both focused and expanded the search for extraterrestrial intelligence.
