A Cool Earth-sized Planet Candidate Transiting a Tenth Magnitude K-dwarf From K2
Alexander Venner, Andrew Vanderburg, Chelsea X. Huang +7
The transit method is currently one of our best means for the detection of potentially habitable "Earth-like" exoplanets. In principle, given sufficiently high photometric precisio…
The HD 60779 Planetary System: A Transiting Sub-Neptune on a 30-day Orbit and a More Massive Outer World
Victoria DiTomasso, David Charbonneau, Andrew Vanderburg +37
We present the discovery of the planetary system orbiting the bright (V = 7.2), nearby (35 pc), Sun-like star HD 60779, which has a mass of 1.050 +/- 0.044 solar masses and a radiu…
Confirmation and Characterization of the Eccentric, Warm Jupiter TIC 393818343 b with a Network of Citizen Scientists
Lauren A. Sgro, Paul A. Dalba, Thomas M. Esposito +21
NASA's Transiting Exoplanet Survey Satellite (TESS) has identified over 7,000 candidate exoplanets via the transit method, with gas giants among the most readily detected due to th…
The Active Asteroids Citizen Science Program: Overview and First Results
Colin Orion Chandler, Chadwick A. Trujillo, William J. Oldroyd +20
We present the Citizen Science program Active Asteroids and describe discoveries stemming from our ongoing project. Our NASA Partner program is hosted on the Zooniverse online plat…
TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain
Fei Dai, Kento Masuda, Corey Beard +60
Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMR). Dynamical evolution over time could…
The Visual Survey Group: A Decade of Hunting Exoplanets and Unusual Stellar Events with Space-Based Telescopes
Martti H. K. Kristiansen, Saul A. Rappaport, Andrew M. Vanderburg +9
This article presents the history of the Visual Survey Group (VSG) - a Professional-Amateur (Pro-Am) collaboration within the field of astronomy working on data from several space…
The TESS-Keck Survey. VIII. Confirmation of a Transiting Giant Planet on an Eccentric 261 day Orbit with the Automated Planet Finder Telescope
Paul A. Dalba, Stephen R. Kane, Diana Dragomir +72
We report the discovery of TOI-2180 b, a 2.8 giant planet orbiting a slightly evolved G5 host star. This planet transited only once in Cycle 2 of the primary Transiting…
Mysterious Dust-emitting Object Orbiting TIC 400799224
Brian P. Powell, Veselin Kostov, Saul Rappaport +24
We report the discovery of a unique object of uncertain nature -- but quite possibly a disintegrating asteroid or minor planet -- orbiting one star of the widely separated binary T…
TESS Hunt for Young and Maturing Exoplanets (THYME) III: a two-planet system in the 400 Myr Ursa Major Group
Andrew W. Mann, Marshall C. Johnson, Andrew Vanderburg +51
Exoplanets can evolve significantly between birth and maturity, as their atmospheres, orbits, and structures are shaped by their environment. Young planets (1 Gyr) offer an oppo…
Planet Hunters TESS I: TOI 813, a subgiant hosting a transiting Saturn-sized planet on an 84-day orbit
N. L. Eisner, O. Barragán, S. Aigrain +47
We report on the discovery and validation of TOI 813b (TIC 55525572 b), a transiting exoplanet identified by citizen scientists in data from NASA's Transiting Exoplanet Survey Sate…
The Random Transiter -- EPIC 249706694/HD 139139
S. Rappaport, A. Vanderburg, M. H. Kristiansen +16
We have identified a star, EPIC 249706694 (HD 139139), that was observed during K2 Campaign 15 with the Kepler extended mission that appears to exhibit 28 transit-like events over…
A Compact Multi-Planet System With A Significantly Misaligned Ultra Short Period Planet
Joseph E. Rodriguez, Juliette C. Becker, Jason D. Eastman +20
We report the discovery of a compact multi-planet system orbiting the relatively nearby (78pc) and bright () K-star, K2-266 (EPIC248435473). We identify up to six possible p…
The K2-138 System: A Near-Resonant Chain of Five Sub-Neptune Planets Discovered by Citizen Scientists
Jessie L. Christiansen, Ian J. M. Crossfield, Geert Barentsen +25
K2-138 is a moderately bright (V = 12.2, K = 10.3) main sequence K-star observed in Campaign 12 of the NASA K2 mission. It hosts five small (1.6-3.3R_Earth) transiting planets in a…
Planet Hunters X: Searching for Nearby Neighbors of 75 Planet and Eclipsing Binary Candidates from the K2 Kepler Extended Mission
Joseph R. Schmitt, Andrei Tokovinin, Ji Wang +22
We present high-resolution observations of a sample of 75 K2 targets from Campaigns 1-3 using speckle interferometry on the Southern Astrophysical Research (SOAR) telescope and ada…
Planet Hunters. VIII. Characterization of 41 Long-Period Exoplanet Candidates from Kepler Archival Data
Ji Wang, Debra A. Fischer, Thomas Barclay +30
The census of exoplanets is incomplete for orbital distances larger than 1 AU. Here, we present 41 long-period planet candidates in 38 systems identified by Planet Hunters based on…
