Hot super-Earths stripped by host stars: 'Cooked' planets shrink due to radiation
Astrophysicists at the University of Birmingham have used data from the NASA Kepler space telescope to discover a class of extrasolar planets whose atmospheres have been stripped away by their host stars, according to research published in the journal Nature Communications today (April 11, 2016). (2016-04-11)

Looking for Earths by looking for Jupiters
In the search for Earth-like planets, it is helpful to look for clues and patterns that can help scientist narrow down the types of systems where potentially habitable planets are likely to be discovered. New research narrows down the search for Earth-like planets near Jupiter-like planets. Their work indicates that the early post-formation movements of hot-Jupiter planets probably disrupt the formation of Earth-like planets. (2012-05-07)

First transiting planets in a star cluster discovered
All stars begin their lives in groups. Most stars are born in small groups that quickly fall apart. Others form in huge, dense swarms, where stars jostle with thousands of neighbors while strong radiation and harsh stellar winds scour interstellar space, stripping planet-forming materials from nearby stars. It would thus seem an unlikely place to find alien worlds. Yet 3,000 light-years from Earth, in the star cluster NGC 6811, astronomers have found two planets smaller than Neptune orbiting sun-like stars. (2013-06-26)

Star tours

Some stars capture rogue planets
New research suggests that billions of stars in our galaxy have captured rogue planets that once roamed interstellar space. The nomad worlds, which were kicked out of the star systems in which they formed, occasionally find a new home with a different sun. This finding could explain the existence of some planets that orbit surprisingly far from their stars, and even the existence of a double-planet system. (2012-04-17)

A new study shows other stars could have as many as seven Earth-like planets in the absence of a gas giant like Jupiter. (2020-07-31)

Five planets revealed after 20 years of observation
To confirm the presence of a planet, it is necessary to wait until it has made one or more revolutions around its star. This can take from a few days for the closest to the star to decades for the furthest away. Only a telescope dedicated to the search for exoplanets can carry out such measurements over such long periods of time, which is the case of the EULER telescope of UNIGE. (2019-04-17)

TRAPPIST-1: Findings show exoplanets made of rock and water
In 2016, a team of researchers led by EU-funded astronomer Michael Gillon at the University of Liege, Belgium, discovered three temperate Earth-sized planets orbiting TRAPPIST-1, an ultra-cool dwarf star just 40 light years from Earth. A few months later, Gillon surprised the world with the discovery of a whole planetary system made of a total of seven planets around this star. A set of new studies reveals today the nature and composition of the planets, shedding light on their potential habitability. (2018-02-05)

OU astrophysicist identifies composition of Earth-size planets in TRAPPIST-1 system
A University of Oklahoma post-doctoral astrophysics researcher, Billy Quarles, has identified the possible compositions of the seven planets in the TRAPPIST-1 system. Using thousands of numerical simulations to identify the planets stable for millions of years, Quarles concluded that six of the seven planets are consistent with an Earth-like composition. The exception is TRAPPIST-1f, which has a mass of 25 percent water, suggesting that TRAPPIST-1e may be the best candidate for future habitability studies. (2017-06-08)

A planet that should not exist
Astronomers detected a giant planet orbiting a small star. The planet has much more mass than theoretical models predict. While this surprising discovery was made by a Spanish-German team at an observatory in southern Spain, researchers at the University of Bern studied how the mysterious exoplanet might have formed. (2019-09-26)
