Of the > 500 confirmed transiting hot jupiters and approximately 2000 additional candidates today, only ten are known to have nearby companion planets. The survival of nearby compa…
A 43 day transiting Neptune and two 25 day Saturns from TESS, NGTS and ASTEP
Alicia Kendall, Solène Ulmer-Moll, Samuel Gill +53
Beyond orbital periods of 10 days, there is a dearth of known transiting gas giants. On longer orbits, planets are less affected by their host star, and become ideal probes of plan…
ExoClock Project IV: A homogeneous catalogue of 620 updated exoplanet ephemerides

The ExoClock project is an open platform aiming to monitor exoplanets by integrating observations from space and ground based telescopes. This study presents an updated catalogue o…
High five from ASTEP: Three validated planets and two eclipsing binaries in a diverse set of long-period candidates
Erika Rea, Maximilian N. Günther, George Dransfield +44
We present the analysis of five long-period TESS Objects of Interest (TOIs), all orbiting Sun-like stars, with orbital periods exceeding one month. Initially identified by the Tran…
A Cold and Super-Puffy Planet on a Prograde Orbit
Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +36
We report the discovery of TOI-4507 b, a transiting sub-Saturn with a density 0.2 g/cm on a 105-day prograde orbit around a 700 Myr old F star. The transits were detected u…
Discovery and Characterization of an Eccentric, Warm Saturn Transiting the Solar Analog TOI-4994
Romy Rodriguez Martinez, Jason D. Eastman, Karen Collins +46
We present the detection and characterization of TOI-4994b (TIC 277128619b), a warm Saturn-sized planet discovered by the NASA Transiting Exoplanet Survey Satellite (TESS). TOI-499…
TESS Hunt for Young and Maturing Exoplanets (THYME) X: a two-planet system in the 210 Myr MELANGE-5 Association
Pa Chia Thao, Andrew W. Mann, Madyson G. Barber +35
Young (<500 Myr) planets are critical to studying how planets form and evolve. Among these young planetary systems, multi-planet configurations are particularly useful as they prov…
The Pictoris b Hill sphere transit campaign. Paper II: Searching for the signatures of the Pictoris exoplanets through time delay analysis of the Scuti pulsations
Sebastian Zieba, Konstanze Zwintz, Matthew Kenworthy +34
The Pictoris system is the closest known stellar system with directly detected gas giant planets, an edge-on circumstellar disc, and evidence of falling sublimating bodies and…
Three Warm Jupiters around Solar-analog stars detected with TESS
Jan Eberhardt, Melissa J. Hobson, Thomas Henning +32
We report the discovery and characterization of three giant exoplanets orbiting solar-analog stars, detected by the \tess space mission and confirmed through ground-based photometr…
Evidence for transit-timing variations of the 11 Myr exoplanet TOI-1227 b
J. M. Almenara, X. Bonfils, T. Guillot +27
TOI-1227 b is an 11 Myr old validated transiting planet in the middle of its contraction phase, with a current radius of 0.85 R. It orbits a low-mass pre-main sequence star (0.…
Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
