A pair of recent studies conduct in-depth analyses of Jupiter-sized exoplanets, also known as Exo-Jupiters, and were published in Nature Communications and The Astronomical Journal, respectively. The study published in Nature Communications was conducted by an international team of researchers and examines how Exo-Jupiters could be more common than previously thought, while the study published in The Astronomical Journal was conducted by one researcher and examines exoplanetary system, HD 141399, and how it is comprised entirely of Exo-Jupiters with no additional planets.Continue reading “Exo-Jupiters’ Commonality and Exclusivity Highlighted in Two New Studies”
The number of planets discovered beyond our Solar System has grown exponentially in the past twenty years, with 4,919 confirmed exoplanets (and another 8,493 awaiting confirmation)! Combined with improved instruments and data analysis, the field of study is entering into an exciting new phase. In short, the focus is shifting from discovery to characterization, where astronomers can place greater constraints on potential habitability.
In particular, the characterization of exoplanet atmospheres will allow astronomers to determine their chemical makeup and whether they have the right characteristics to support life. In a new study led by the University of Lund, an international team of researchers characterized the atmosphere of one of the most extreme exoplanets yet discovered. This included discerning what could be several distinct layers that have particular characteristics.Continue reading “Astronomers Measure the Layers of an Exoplanet's Atmosphere”
