Planets orbiting “short-period” binary stars, or stars locked in close orbital embrace, can be ejected off into space as a consequence of their host stars’ evolution, according to new research from the University of Washington.

A University of Washington-led international team of astronomers has used data gathered by the Kepler Space Telescope to observe and confirm details of the outermost of seven exoplanets orbiting the star TRAPPIST-1.

New research from the UW-based Virtual Planetary Laboratory will help astronomers better identify — and thus rule out — “false positives” in the search for life beyond Earth.

Two phenomena known to inhibit the potential habitability of planets — tidal forces and vigorous stellar activity — might instead help chances for life on certain planets orbiting low-mass stars, University of Washington astronomers have found.

Planets orbiting close to low-mass stars are prime targets in the search for life. But new research led by an astronomy graduate student at the UW indicates some such planets may have long since lost their chance at hosting life because of intense heat during their formative years.
