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…
TOI-6692b: An eccentric 130 day period giant planet with a single transit from TESS
Allyson Bieryla, Karen A. Collins, George Zhou +46
We report the discovery and characterization of TOI-6692 b, an eccentric (e~0.54) Jupiter on a 130-day orbit. TOI-6692 b was first detected as a community TESS Object of Interest (…
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…
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 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…
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…
Catalog of New K2 Exoplanet Candidates from Citizen Scientists
Jon K. Zink, Kevin K. Hardegree-Ullman, Jessie L. Christiansen +34
We provide 28 new planet candidates that have been vetted by citizen scientists and expert astronomers. This catalog contains 9 likely rocky candidates () and…
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…
Three small planets transiting the bright young field star K2-233
Trevor J. David, Ian J. M. Crossfield, Björn Benneke +14
We report the detection of three small transiting planets around the young K3 dwarf K2-233 (2MASS J15215519-2013539) from observations during Campaign 15 of the K2 mission. The sta…
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…
WASP-47: A Hot Jupiter System with Two Additional Planets Discovered by K2
Juliette C. Becker, Andrew Vanderburg, Fred C. Adams +2
Using new data from the K2 mission, we show that WASP-47, a previously known hot Jupiter host, also hosts two additional transiting planets: a Neptune-sized outer planet and a supe…
Planet Hunters. VI: An Independent Characterization of KOI-351 and Several Long Period Planet Candidates from the Kepler Archival Data
Joseph R. Schmitt, Ji Wang, Debra A. Fischer +29
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…
