Papillon7, Franco Rossi7, and Miguel Socolovsky7 [email protected] ABSTRACT We report the discovery of 14 new transiting planet candidates in the Kepler field from the Planet Hunters citizen science program. None of these candidates overlapped with Kepler Objects of Interest (KOIs) at the time of submission. We report the discovery of one more addition to the six planet candidate system around KOI-351, making it the only seven planet candidate system from Kepler. Additionally, KOI-351 bears some resemblance to our own solar system, with the inner five planets ranging from Earth to mini-Neptune radii and the outer planets being gas giants; however, this system is very compact, with all seven planet candidates orbiting . 1 AU from their host star. A Hill stability test and an orbital integration of the system shows that the system is stable. Furthermore, we significantly add to the population of long period 1This publication has been made possible through the work of more than 280,000 volunteers in the Planet Hunters project, whose contributions are individually acknowledged at http://www.planethunters.org/authors. -

January 2019, the Role of Citizen Scientists in New Discoveries
Astrobiology News January 2019: The Role of Citizen Scientists in New Discoveries Zooniverse is the world’s largest and most popular platform for online citizen science.1 Last month, I mentioned the launch of Planet Hunters TESS; this month, I want to tell you about two exciting new discoveries by citizen scientists participating in Exoplanet Explorers, which uses data from the Kepler Observatory’s Second Mission.2 Both discoveries are described extensively in Zooniverse blogs posted on January 7th.3 Exoplanet K2-288b orbits in the habitable zone of the smaller of two low- mass red dwarf stars that form a binary system. Its size places it in a rare category of planets being dubbed “sub-Neptunes” – worlds thought to lie in a transition region between potentially habitable “super-Earths” and worlds more like the gas giants in our Solar System. K2-138g, just a bit smaller than Neptune, is the 6th planet discovered in the K2-138 system, which harbors a somewhat more massive “orange dwarf” star. The K2- 138 system shares some similarities with the TRAPPIST-1 system, which you can read more about in the Astrobiology News posts from March and May 2017.4 What makes the K2-138 and TRAPPIST-1 systems similar is that the planets all orbit close to their stars, with very short periods. Five of the 6 planets in K2-138, and all 7 planets in the TRAPPIST-1 system, form a so- called resonant chain, where the planet orbits are related by the ratios of small integers. The orbiting bodies in such systems exert periodic gravitational influence on each other. -

Exploring Exoplanet Populations with NASA's Kepler Mission
SPECIAL FEATURE: PERSPECTIVE PERSPECTIVE SPECIAL FEATURE: Exploring exoplanet populations with NASA’s Kepler Mission Natalie M. Batalha1 National Aeronautics and Space Administration Ames Research Center, Moffett Field, 94035 CA Edited by Adam S. Burrows, Princeton University, Princeton, NJ, and accepted by the Editorial Board June 3, 2014 (received for review January 15, 2014) The Kepler Mission is exploring the diversity of planets and planetary systems. Its legacy will be a catalog of discoveries sufficient for computing planet occurrence rates as a function of size, orbital period, star type, and insolation flux.The mission has made significant progress toward achieving that goal. Over 3,500 transiting exoplanets have been identified from the analysis of the first 3 y of data, 100 planets of which are in the habitable zone. The catalog has a high reliability rate (85–90% averaged over the period/radius plane), which is improving as follow-up observations continue. Dynamical (e.g., velocimetry and transit timing) and statistical methods have confirmed and characterized hundreds of planets over a large range of sizes and compositions for both single- and multiple-star systems. Population studies suggest that planets abound in our galaxy and that small planets are particularly frequent. Here, I report on the progress Kepler has made measuring the prevalence of exoplanets orbiting within one astronomical unit of their host stars in support of the National Aeronautics and Space Admin- istration’s long-term goal of finding habitable environments beyond the solar system. planet detection | transit photometry Searching for evidence of life beyond Earth is the Sun would produce an 84-ppm signal Translating Kepler’s discovery catalog into one of the primary goals of science agencies lasting ∼13 h. -
