LOFAR pioneers new way to study exoplanet environments

Using the Dutch-led Low Frequency Array (LOFAR)​ ​radio telescope, astronomers have discovered unusual radio waves coming from the nearby red dwarf star GJ1151. The radio waves bear the tell-tale signature of aurorae caused by an interaction between a star and its planet. The radio emission from a star-planet interaction has been predicted for over thirty-years … Read more LOFAR pioneers new way to study exoplanet environments

OU researchers make new discoveries set to reveal the geology of planets outside our Solar System

Three OU astronomers today announce ground-breaking discoveries allowing scientists to understand planets outside our Solar System. Professor Carole Haswell, Dr Daniel Staab and Dr John Barnes discovered three, new, nearby planetary systems. Research led by Professor Haswell found the exoplanets – planets outside the Solar System – as part of the Dispersed Matter Planet Project … Read more OU researchers make new discoveries set to reveal the geology of planets outside our Solar System

Water common – yet scarce – in exoplanets

The most extensive survey of atmospheric chemical compositions of exoplanets to date has revealed trends that challenge current theories of planet formation and has implications for the search for water in the solar system and beyond. A team of researchers, led by the University of Cambridge, used atmospheric data from 19 exoplanets to obtain detailed … Read more Water common – yet scarce – in exoplanets

Hidden giant planet revealed around tiny white dwarf star

The first evidence of a giant planet orbiting a dead white dwarf star has been found in the form of a disc of gas formed from its evaporating atmosphere. The Neptune-like planet orbits a star a quarter of its size about once every ten days, leaving a comet-like tail of gas comprised of hydrogen, oxygen … Read more Hidden giant planet revealed around tiny white dwarf star

Exoplanet interiors have Earth-like geochemistry

Earth-like planets may be common in the universe, a new UCLA study implies. The team of astrophysicists and geochemists presents new evidence that the Earth is not unique. The study was published in the journal Science on Oct. 18. “We have just raised the probability that many rocky planets are like the Earth, and there’s a very … Read more Exoplanet interiors have Earth-like geochemistry
