Coralie radial-velocity search for companions around evolved stars (CASCADES) III. A new Jupiter host-star: in-depth analysis of HD 29399 using TESS data
C. Pezzotti, G. Ottoni, G. Buldgen +11
Context. Increasing the number of detected exoplanets is far from anecdotal, especially for long-period planets that require a long duration of observation. More detections imply a…
Orbital misalignment of the super-Earth Men c with the spin of its star
Vedad Kunovac Hodžić, Amaury H. M. J. Triaud, Heather M. Cegla +2
Planet-planet scattering events can leave an observable trace of a planet's migration history in the form of orbital misalignment with respect to the the stellar spin axis, which i…
TOI-257b (HD 19916b): A Warm sub-Saturn Orbiting an Evolved F-type Star
Brett C. Addison, Duncan J. Wright, Belinda A. Nicholson +91
We report the discovery of a warm sub-Saturn, TOI-257b (HD 19916b), based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The transit signal was detected by TESS…
The Curious Case of KOI 4: Confirming Kepler's First Exoplanet
Ashley Chontos, Daniel Huber, David W. Latham +13
The discovery of thousands of planetary systems by Kepler has demonstrated that planets are ubiquitous. However, a major challenge has been the confirmation of Kepler planet candid…
A Hot Saturn Orbiting An Oscillating Late Subgiant Discovered by TESS
Daniel Huber, William J. Chaplin, Ashley Chontos +139
We present the discovery of TOI-197.01, the first transiting planet identified by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology of the host star is po…
Time-Series Analysis of Broadband Photometry of Neptune from K2
Jason F. Rowe, Patrick Gaulme, Jack J. Lissauer +19
We report here on our search for excess power in photometry of Neptune collected by the K2 mission that may be due to intrinsic global oscillations of the planet Neptune. To conduc…
Spin-orbit alignment of exoplanet systems: ensemble analysis using asteroseismology
T. L. Campante, M. N. Lund, J. S. Kuszlewicz +23
The angle between a planet's orbital axis and the spin axis of its parent star is an important diagnostic of planet formation, migration, and tidal evolution. We seek empirical…
The Kepler-454 System: A Small, Not-rocky Inner Planet, a Jovian World, and a Distant Companion
Sara Gettel, David Charbonneau, Courtney D. Dressing +47
Kepler-454 (KOI-273) is a relatively bright (V = 11.69 mag), Sun-like starthat hosts a transiting planet candidate in a 10.6 d orbit. From spectroscopy, we estimate the stellar tem…
WASP-135b: a highly irradiated, inflated hot Jupiter orbiting a G5V star
Jessica J. Spake, David J. A. Brown, Amanda P. Doyle +27
We report the discovery of a new transiting planet from the WASP survey. WASP-135b is a hot Jupiter with a radius of 1.30 pm 0.09 Rjup, a mass of 1.90 pm 0.08 Mjup and an orbital p…
KOI-3158: The oldest known system of terrestrial-size planets
T. L. Campante, T. Barclay, J. J. Swift +38
The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. Whil…
An ancient extrasolar system with five sub-Earth-size planets
T. L. Campante, T. Barclay, J. J. Swift +38
The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-r…
Kepler-432: a red giant interacting with one of its two long period giant planets
Samuel N. Quinn, Timothy R. White, David W. Latham +28
We report the discovery of Kepler-432b, a giant planet () transiting an evolved star $(M_\star =…
Asteroseismic inference on the spin-orbit misalignment and stellar parameters of HAT-P-7
Mikkel N. Lund, Mia Lundkvist, Victor Silva Aguirre +12
The measurement of obliquities in star-planet systems is of great importance for the understanding of planet system formation and evolution. The bright and well studied HAT-P-7 sys…
Kepler-93b: A Terrestrial World Measured to within 120 km, and a Test Case for a New Spitzer Observing Mode
Sarah Ballard, William J. Chaplin, David Charbonneau +22
We present the characterization of the Kepler-93 exoplanetary system, based on three years of photometry gathered by the Kepler spacecraft. The duration and cadence of the Kepler o…
Masses, Radii, and Orbits of Small Kepler Planets: The Transition from Gaseous to Rocky Planets
Geoffrey W. Marcy, Howard Isaacson, Andrew W. Howard +100
We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are 49 planet candidates around these stars, including 42 detected through transits and 7…

Asteroseismic determination of obliquities of the exoplanet systems Kepler-50 and Kepler-65
W. J. Chaplin, R. Sanchis-Ojeda, T. L. Campante +26
Results on the obliquity of exoplanet host stars -- the angle between the stellar spin axis and the planetary orbital axis -- provide important diagnostic information for theories…
