Planetary rings such as those around Saturn are fascinating features. Recent observations also reveal evidence for rings around exoplanets, but it’s a difficult task to distinguish these planets from ringless planets. This Astrobite presents a technique, which simplifies the search for candidates. Even better, the developed code is publicly available and allows you going out to look for candidates for exoplanetary rings.
A new analysis technique, that fits simultaneously for light-curve systematics and transit signals, finds 36 planet candidates in the K2 dataset — Kepler is still in the game!
Most exoplanets are and have been detected by the transit method. Maybe, we can improve the method even further by drawing conclusions from the recent Venus transits in 2004 and 2012.
MINERVA: Detecting Super-Earths from the ground in a modular, cost-effective manner.
The Kepler Mission has measured planet radii and orbital periods for 3,000+ light curves. So what is next? Either we convince the continental USA to become amateur astronomers… Or we figure out ways to retrieve more planetary parameters from the Kepler data set. I’ll stick with the later. And so will the authors or this paper.
Artist’s impressions of exoplanets are often wrong!
