Exoplanet orbital and physical parameters

Exoplanets pushing their atmospheres away may explain a gap in exoplanet masses, according to a team of researchers that recently studied data from NASA’s retired Kepler Space Telescope.What Is Planet Nine and Why Can’t We Find It?The activity could explain an absence of exoplanets with masses between 1.5 to 2 times the size of Earth, according to findings published this week in The Astronomical Journal.“Exoplanet scientists have enough data now to say that this gap is not a fluke,” said Jessie Christiansen, a research…

Researchers think they’ve gotten a glimpse at how gas giants like Jupiter form, thanks to a remarkable image of a distant star system.First Full-Color Images From Webb Space TelescopeAt the heart of the system is V960 Mon, a young star about 5,000 light-years away, in the constellation Monoceros. The star brightened to about 20 times its normal levels in 2014, allowing a research team using the European Southern Observatory’s Spectro-Polarimetric High-contrast Exoplanet Research instrument, or SPHERE, to image it. The…

The search for planets outside our Solar System – exoplanets – is one of the most rapidly growing fields in astronomy. Over the past few decades, more than 5,000 exoplanets have been detected and astronomers now estimate that on average there is at least one planet per star in our galaxy.What Is Planet Nine and Why Can’t We Find It?Many current research efforts aim at detecting Earth-like planets suitable for life. These endeavours focus on so-called “main sequence” stars like our Sun – stars which are powered by fusing…
