A Plethora of Planets: Number of Known Exoplanets SoaringJohn Matson
the number of short-period exoplanets, followed by a minimum of planets between around 7 and 50 days and then an apparent rise in the number of ... HRA Jones,RP Butler,CG Tinney,... - 《Monthly Notices of the Royal Astronomical Society》 被引量: 100发表: 2002年 Comparing the Mass-Per...
In the study, researchers first trained the neural network they developed to identify exoplanets using 15,000 signals from Kepler data that have already been examined previously. It turned out the neural network correctly identified true planets and false positives 96 percent of the time. Then, wit...
Exploring the potential of the ExoSim simulator for transit spectroscopy noise estimation The technique of transit spectroscopy has given us our first insights into the atmospheric features of exoplanets. The extremely low signals involved in de... S Sarkar,A Papageorgiou,E Pascale - Spie Astronomical...
“This result was only possible because we believed that, when combining space and ground-based facilities to directly image exoplanets, the whole is greater than the sum of its parts. We hope that this will be the start of a new era of synergy between different instruments and detection meth...
- 《Proceedings of Spie》 被引量: 24发表: 2012年 Astrophysical Conditions for Planetary Habitability With the discovery of hundreds of exoplanets and a potentially huge number ofEarth-like planets waiting to be discovered, the conditions for theirhabitabil... M Guedel,R Dvorak,N Erkaev,... -...
Rogue planets have historically been difficult to detect. Astronomers discovered planets outside Earth's solar system in the 1990s. Those planets, called exoplanets, range from extremely hot balls of gas to rocky, dusty worlds. Many of them circle their own stars, the way Earth circles the sun...
He primarily covers exoplanets, spaceflight and military space, but has been known to dabble in the space art beat. His book about the search for alien life, "Out There," was published on Nov. 13, 2018. Before becoming a science writer, Michael worked as a herpetologist and wildlife ...
Planetary nebulae is an inaccurate term for these objects because they are unrelated to planets or exoplanets. PNe are important tools used to estimate distances, despite the brief lifespans of their terminal phases (~30,000–50,000 y). In 1963, Karl G. Henize and Bengt E. Westerlund ...
If, once we detect several biospheres, we find a correlation between the age of the star and the presence of life, we will have falsified this prediction the multiverse has made. Upcoming experiments aimed at characterizing the atmospheres of exoplanets will make this task feasible. This logic ...
